Tau'ri-Goa'uld skirmishes

This is a list of skirmishes that have occurred in the Milky Way galaxy between the Tau'ri and the Goa'uld during the Goa'uld dominance over the Galaxy.

Apophis' attack on the SGC
As five United States Air Force Airman are playing poker, Apophis and several Jaffa led by his First Prime Teal'c arrive on Earth through the Stargate on a mission to search for hosts. The group captures Senior Airman Carol Weterings and enter a firefight with the other four Airman. In the fight, one Jaffa is killed and so are all of the other airmen before Apophis, Teal'c and his remaining Jaffa retreat through the Stargate. As they leave, Major General George S. Hammond runs into the room with more men and witnesses Apophis' eyes glow, causing him to believe that Ra survived.

Back to Abydos
The appearance of Apophis in Stargate Command and the revealing of the fact that Dr. Daniel Jackson and the people of Abydos surviving causes Major General George S. Hammond to send another team to Abydos led by Colonel Jack O'Neill and including Captain Samantha Carter, Major Charles Kawalsky and Major Louis Ferretti. As the team is shown a massive cartouche of Stargate addresses, Apophis and his men arrive through the Stargate on another hunt for hosts. The Earth team and the Abydonian militia engage the Jaffa, but are defeated. Skaara tries to stop them from taking Sha're and is captured by Teal'c who is interested in him as he's using an Earth weapon and he and Sha're are taken through the Stargate, but Ferretti, badly injured but still conscious, manages to see the Stargate address Apophis dials. As a result of the attack, Jackson willingly returns to Earth in hopes of being able to rescue Sha're and Skaara.

Skirmish on Chulak
After the attack on Abydos, Earth learns the location of Chulak from Major Louis Ferretti who saw where Apophis and his men dialed when they left Abydos. In an attempt to learn more about this new enemy and rescue Sha're and Skaara, the newly formed SG-1 and SG-2 led by Colonel Jack O'Neill and Major Charles Kawalsky travel there. After being mistaken for Goa'uld's looking for hosts, SG-1 are taken to the main city while SG-2 stays behind. At the city, Apophis arrives with Sha're now host to his queen Amaunet. When Dr. Daniel Jackson tries to reach Sha're, he is thrown away by Apophis's Kara kesh and O'Neill tries to shoot Apophis but hesitates when Amaunet steps in the way and is knocked out.

After waking up, Apophis and other Goa'ulds arrive to choose from the prisoners who will be a host and among them Skaara is chosen. After the newly selected hosts are taken away, Apophis orders his men to kill the remaining prisoners before leaving, but O'Neill convinces Apophis' First Prime Teal'c to help him and Teal'c shoots one of the guards before tossing O'Neill his Staff weapon. Together they kill the guards in the room and scare off the ones outside before O'Neill uses the staff weapon to blow a hole in the outside wall for them and the prisoners to escape through. At first Teal'c stays behind as due to his betrayal he has nowhere to go, but O'Neill invites him to come with them.

As the group travels to the Stargate, they come under attack by a Death Glider and O'Neill and Teal'c try to shoot it down with their staff weapons to no avail until Major Carl Warren from SG-2 takes it out from nearby with a FIM-92 Stinger missile. The group reaches the Stargate where O'Neill tries to reach Skaara, but Skaara now has a Goa'uld implanted in him and throws him back with his Kara kesh before leaving with the other Goa'uld including Apophis and Amaunet through the Stargate. O'Neill misses the address so the group has no way of following them.

As the group prepares to dial Earth, a Jaffa battalion arrives and Warren and Casey shoot at them, trying to hold them off, but are eventually forced to fall back. Jackson manages to dial the Stargate and Captain Samantha Carter sends the IDC just in time as the Iris is about to be permanently closed. Jackson and Carter usher the former prisoners through the Stargate as the others hold off the Jaffa as best they can. When the Jaffa reach the top of a nearby hill, the Kawalsky triggers A-M18A1 Claymore mines laid there killing a bunch of Jaffa, but more keep coming. Jackson gets all of the prisoners through the Stargate and goes through himself, but as everyone else follows, Casey is hit by a staff blast and wounded. As Kawalsky helps him to the Stargate, one of the prisoners squeezes one of the Jaffa to death and his symbiote enters Kawalsky as he passes nearby. Everyone gets through the Stargate and the iris is closed, taking out the remaining Jaffa who try to follow.

Kawalsky's infestation by a Goa'uld
While escaping from Chulak, Major Charles Kawalsky is infected with a Goa'uld who can only take control of him periodically as its still not completely mature. Complaining of a headache, Kawalsky visits Dr. Nimzicki, but the Goa'uld takes control and kills him when the doctor finds the spot that the Goa'uld entered through. Later, when Dr. William Warner does an MRI and discovers it, the Goa'uld takes control again and escapes as Warner activates the alarm.

The Goa'uld travels to the Stargate Operations room where it beats up the technicians and tries to dial the Stargate, but is found by Captain Samantha Carter who it takes hostage and uses to get into an elevator that it starts to take to the surface. The Goa'uld throws Carter against a wall, knocking her out, but before it can do anymore, Kawalsky regains control with no memory of what happened and stops the elevator upon seeing Carter hurt. Kawalsky is strapped down and after the idea of trying to surgically remove the Goa'uld is revealed as dangerous by Teal'c as the Goa'uld will likely kill the host if its tried, the Goa'uld is offered its freedom in exchange for leaving Kawalsky permanently. It refuses and its decided to try to surgically remove the Goa'uld. Using an anesthetic picked out by experimenting on Teal'c's Goa'uld, the operation goes ahead and the Goa'uld is removed with apparently no ill effects for Kawalsky. However, the Goa'uld has in reality gained permanent control over Kawalsky's body and claiming to want to thank Teal'c, approaches him offering to serve it and when he refuses, it briefly chokes him before knocking out the guards outside and heading to the Control Room.

In the Control Room, it injures MSgt. Walter Harriman and dials the Stargate to Chulak, setting the base Self-destruct at the same time. The Goa'uld tries to escape through the Stargate, but is stopped by Teal'c who fights him in front of the Gate. Colonel Jack O'Neill and Major General George S. Hammond deactivate the self-destruct before O'Neill has Teal'c hold Kawalsky's head partially in the event horizon then has Harriman shut down the Stargate, cutting off part of the top of Kawalsky's head, killing him and the Goa'uld who is revealed to have still had a piece of itself in Kawalsky's head which falls out and shrivels up when Kawalsky is killed.

Skirmish with Ruax
Wanting to find possible allies against the Goa'uld, SG-1 travels to Cimmeria where something happened in the past that the Goa'uld will not speak of. Once there, the team is scanned for Goa'uld symbiotes by an obelisk and it detects Teal'c's symbiote and starts to beam him into the Labyrinth leading to Thor's Hammer, but Colonel Jack O'Neill grabs on and is beamed in as well. In order to find the two, the rest of the team has Gairwyn take them to Kendra a former Goa'uld host who was freed by Thor's Hammer so she can lead them to where she came out. Kendra is reluctant, but eventually agrees to lead Captain Samantha Carter and Dr. Daniel Jackson to the spot. As O'Neill and Teal'c make their way through the Labyrinth, they find the bones of Goa'ulds and their hosts eaten by the Unas Ruax and their presence wakes him up. He attacks the two, demanding Teal'c kill O'Neill, but O'Neill shoots him, apparently killing him, but Ruax's healing powers keep him alive and he quickly recovers. Ruax catches up and attacks again, but O'Neill and Teal'c shoot again and run, but Ruax quickly recovers.

The two reach the Hammer and O'Neill is able to leave, but the Hammer starts to kill Teal'c's symbiote so O'Neill pulls him out of the beam and the two get ready to face Ruax. The two manage to maneuver Ruax in front of the Hammer and open fire, trying to knock him into the Hammer, but while he's weakened, he manages to keep from falling in so after they run out of ammunition, Teal'c shoves him in and both are affected by the Hammer. O'Neill pulls Teal'c out of the Hammer and the Hammer kills Ruax's Goa'uld. Ruax's host is mortally wounded by O'Neill and Teal'c's gunfire and dies without Ruax to heal it. O'Neill and Teal'c reunite with Jackson, Carter and Kendra and Teal'c is freed when Jackson uses Teal'c's Staff weapon to destroy Thor's Hammer from the outside. In order to protect the people of the planet, the team requests they seal the entrance so any Goa'uld or Jaffa who come to the planet will hopefully be trapped in the Labyrinth.

Hathor's infiltration of the SGC
The Goa'uld Queen, Hathor, who was revived in Mexico in 1998 found her way to the Stargate in Stargate Command. She was detained by SFs when she trespassed into the SGC. Hathor used her breath, which contained Nish'ta pheromones to influence her way into the personnel of the SGC, including Major General George S. Hammond, and made Colonel Jack O'Neill as her new First Prime, once she implants him with a Symbiote. However, Teal'c, Captain Samantha Carter, Dr. Janet Fraiser and several women members of the SGC managed to stopped Hathor. However, she escapes through the Stargate. The only known injuries were Teal'c, and Fraiser, who were shot by influenced SFs.

Apophis' attack on Cartago
Returning to Cartago after Major General George S. Hammond refuses to mount a rescue mission for Teal'c who is sentenced to death by the Byrsa, Captain Samantha Carter and Colonel Jack O'Neill find the Jaffa have arrived to harvest members of the population to be hosts to Goa'uld symbiotes. The Jaffa notice Carter and O'Neill who kill one and take his staff weapon. At the same time, the Jaffa have figured out where the Byrsa's hidings are and cut them off from them. The Byrsa men try to draw the Jaffa away from the children and slowest members of their people with the help of Carter and O'Neill who kills two with a staff weapon, but a few led by Shak'l find the children and Teal'c. One of the children hands Teal'c a knife and he kills Shak'l. Taking a staff weapon, Teal'c takes on the Jaffa who are going after the villagers, shooting one in the back but finding no clean shot on the other two. Seeing one is going to shoot a crowd of helpless villagers, Teal'c dives in the way and takes the shot, tackling the second Jaffa. Before Teal'c can be killed by the last Jaffa, O'Neill kills him with his stolen staff weapon. Teal'c's actions cause Hanno to accept that Teal'c is not the same man who murdered his father and he lets him go. SG-1 offer the Byrsa help in defending themselves from the Goa'uld which they accept.

Skirmish on P4A-771
When SG-1 arrived on P4A-771 they came under fire from Goa'uld staff weapons. They were surrounded so Dr. Daniel Jackson quickly dialed the gate for they could retreat back to Earth. Jackson and Teal'c made it through with Colonel Jack O'Neill and Captain Samantha Carter a little behind them. Right as they were about to go through one of the staff blasts hit the Stargate. This caused Jackson and Teal'c to be launched out of the gate at Stargate Command at such a force it rendered Jackson unconscious and also caused a disruption in the Stargate which sent O'Neill and Carter to the second Stargate on Earth located in Antarctica. While they were trapped there repairs were made on the SGC side and around a day later Major General George S. Hammond sent a MALP back to the planet but there was no sign of O'Neill or Carter and the MALP was quickly destroyed by the staff blasts. Due to this Hammond ordered they that would not attempt to return to the planet for a rescue mission.

Skirmish on Alternate Earth
While on a mission to P3R-233, Doctor Daniel Jackson accidentally activates and uses the Quantum Mirror and is transported to an alternate reality. There, he learns that Earth is under attack by the Goa'uld System Lord Apophis and Washington and Philadelphia have just been destroyed. Many cities across Europe, Asia and Africa have been destroyed by the Goa'uld and all efforts by the world's militaries to stop the attack have failed. When he arrives, the Goa'uld are starting their attack in the United States, going from the East Coast to the West Coast with efficiency and destroying everything and everyone in their wake, leaving no survivors. At that point, the death toll is estimated to be 1.5 billion. In order to save as many important people such as world leaders, scientists and doctors as they can, the people of the alternate SGC begin evacuating them to the Beta Site, but Jack O'Neill, who is a General in that reality, has a nuclear weapon sent through the Stargate to Chulak after being given the coordinates by Daniel in an attempt to stop the attack and strike back. In response, the Goa'uld dial into the Stargate to keep the SGC from dialing out again and escaping or attacking. Air Force One heads for the SGC to bring in the President to be evacuated, but is shot down by a Ha'tak which lands on Cheyenne Mountain to invade the SGC with troops. In response, O'Neill orders the secondary elevator shaft blown and troops positioned to protect the base. Though he wants to send all non-essential personnel to the Beta Site, the Goa'uld wormhole blocking the Stargate prevents it. While O'Neill and his men defend the SGC, Doctor Samantha Carter agrees to try dialing out when the wormhole closes as she believes it will around half an hour after it first opened. In the meantime, Carter and Doctor Catherine Langford show Daniel a message they received from the people of the P3R-233 of their reality that states "Beware the destroyers. They come from" and then a bunch of numbers they realize represents a Stargate address. Before they can figure out what the Stargate address is, the Stargate shuts down but they aren't able to dial out in time. Carter agrees to try to speed up the dialing process, but they have to wait 38 minutes to be able to try again and they realize they may not have that much time. On Level 2, O'Neill leads a defense against the invading Jaffa who are led by the alternate Teal'c, but eventually his position is overrun and he has to retreat. When he returns to the SGC Briefing Room, Daniel has figured out the Stargate address in the message where the Goa'uld attack presumably originated from. While O'Neill wants to use the next chance they have to send another bomb through to the address, Daniel wants to use the opportunity to return to his own reality so he can use the information to stop the attack he believes is coming there. He manages to convince O'Neill to help him. Needing to buy more time to get the Stargate open, Daniel convinces O'Neill to try to ask Teal'c for help with stopping the attack so he can return to his world and save it, using the video tape he made of his mission to P3R-233 to show Teal'c that he and O'Neill are friends in an alternate reality. Colonel Hammond and his men prepare to defend the Gate Room level from the Jaffa to buy more time to open the Stargate and set the self-destruct so the Goa'uld won't capture the SGC intact. O'Neill seems to come close to convincing Teal'c, but when he brings up the fact that the Teal'c from Daniel's reality changed sides to free his family and his people, Teal'c angrily tells him that O'Neill killed his family when he sent his nuclear weapon to Chulak and kills him in revenge. With only a few minutes left, Hammond and his men are overwhelmed by Jaffa and Carter, who goes to get the Quantum Mirror Control, blows herself and a group of Jaffa up with a grenade. Jaffa take the Control Room, presumably killing Catherine just after the Stargate shuts down and she starts dialing P3R-233 while Jaffa try to blast their way into the Gate Room. They eventually succeed and Teal'c gets in, but hesitates when he sees Daniel. The faster dialing program works and the Stargate is successfully dialed to P3R-233. Daniel escapes through the Stargate, but when he runs for it, Teal'c fires at him, hitting him in the shoulder. Seconds after Daniel leaves, the self-destruct goes off, destroying the SGC and killing the Jaffa inside. Afterwards, Earth is presumably conquered by the Goa'uld, but Daniel is able to use the Quantum Mirror to return to his reality where SG-1 uses the information gathered from the alternate reality to avert Apophis' attack on Earth.

Skirmish on Nassya
The planet Nasya is under Goa'uld attack and SG-1 is tring to help a group of local Nasyans flee through the Stargate. Captain Samantha Carter stops to give CPR to Quinta a fallen villager. He suddenly grabs her head, and Jolinar of Malkshur, a Tok'ra symbiote possesses her. She travels back to Stargate Command and she is hunted and killed by Edrekh an Ashrak sent by Cronus. Fortunately, Jolinar was able to save Carter's life.

Heru'ur's attack on Cimmeria
After SG-1 destroyed Thor's Hammer to rescue Teal'c from being trapped, the Goa'uld System Lord Heru'ur comes to Cimmeria and takes over the planet to be part of his territory, killing former Goa'uld host Kendra in the process and destroying the Cimmerian's village and most of their farms and killing over half of their people. Following Kendra's last instructions, Gairwyn sends the Sagan Institute Box through the Stargate to Earth in hopes of getting help from the Tau'ri. However, while she survives, her husband and his brothers are killed in the process along with one Jaffa. SG-1 travels to Cimmeria to discover Thor's Hammer destroyed and three pyramid landing pads under construction. Soon after meeting up with Gairwyn, SG-1 comes under attack by Jaffa. They kill two, but are forced to retreat when more show up. Needing to find out more information on Heru'ur and his troops, Colonel Jack O'Neill and Teal'c scout the Jaffa encampment with the help of Olaf, but Olaf is captured by Heru'ur and his Horus Guards. Looking for information on SG-1, Heru'ur starts to torture Olaf with his Kara kesh, but O'Neill and Teal'c kill several of his Jaffa, allowing Olaf to escape. Heru'ur protects himself with his personal shield during the fight, but Teal'c manages to destroy a staff weapon he reaches for causing Heru'ur to order the Stargate to be guarded. Needing to find a way to stop Heru'ur and his troops before his Ha'tak's arrive, O'Neill, Teal'c and Olaf decide to use claymores to cause as much damage as possible while Captain Samantha Carter, Dr. Daniel Jackson and Gairwyn go to the Hall of Thor's Might which they believe may contain Asgard weapons they can use to defeat the Goa'uld. O'Neill, Teal'c and Olaf engage a Jaffa patrol, killing them with a combination of their weapons and the claymores but leave when another patrol starts coming. As a result of the ambush, the Jaffa start to use an interlacing hunting pattern to locate SG-1 and the Cimmerians and sweep in and corner them. At the same time, Jackson, Carter and Gairwyn manage to pass the Test of Worthiness in the Hall of Might and find out that the reward isn't weapons, but to meet Thor himself in his true form, a Roswell Gray alien. Thor explains that the tests were meant to determine if the Cimmerians were advanced enough to see the Asgard as they really are and is not pleased to learn of the destruction of the Hammer and the fact that the Goa'uld are attacking Cimmeria. However, he does nothing but send Jackson and Carter back to outside the Hall and cause Gairwyn to disappear. Soon after SG-1 reunites, the Jaffa find the cave where they are hiding with the Cimmerians and demand the surrender of SG-1, proclaiming that otherwise they will kill everyone and if they surrender, the Cimmerians will be allowed to live. Outnumbered twenty to one, SG-1 surrenders to spare the Cimmerians. As the Jaffa escort SG-1 to their encampment, Thor arrives in his ship, the Biliskner and attacks, sending out waves of energy that cause the Jaffa and their encampment to disappear while destroying the pyramids. However, Heru'ur escapes through the Stargate before Thor can get him too. With the invasion over, Thor sends Gairwyn back who explains that Thor has told her to tell SG-1 that the Asgard have visited Earth often and are friends and protectors of all but the Goa'uld who they are at war with. Thor also refuses to meet SG-1 face to face as he believes the Tau'ri are too "young." To protect the Cimmerians from further invasion, Thor will build a new Hammer that will make an exception for Teal'c so he can safely visit Cimmeria and will send an Asgard teacher to help the Cimmerians rebuild.

Heru'ur's attack on Abydos
Wanting Apophis and Amaunet's child, Heru'ur travels to Abydos and lands on the planet's pyramid with his ship. He dispatches forces to capture the Harcesis, but they fail thanks to the sudden arrival of Colonel Jack O'Neill and Captain Samantha Carter which results in the deaths of Heru'ur's forces. Heru'ur himself then faces off against SG-1 with his personal shield protecting him, but after O'Neill throws a knife through his shield and into his Kara kesh, disabling it, Heru'ur retreats to his Ha'tak and leaves the planet alone. Ultimately Apophis returns and leaves with Amaunet, having been falsely told by Amaunet that Heru'ur has the child.

Sokar's attack on Earth
After receiving coordinates from what is believed to be the Tok'ra, SG-1 travels to PB5-926 where a Death Glider is chased by two other Gliders and crashes. The pilot turns out to be Apophis who begs for the team's help. Chased by the Gliders, the team takes Apophis through the Stargate to Earth where he demands sanctuary. It's discovered that Apophis is not only severely injured, but the symbiote has been tortured as well and both the host and symbiote are dying as a result. Also, without a Sarcophagus to sustain him, Apophis begins to age as his body is over ten thousand years old. Apophis reveals that Sokar is the one who tortured him and offers all of his knowledge in exchange for a new host in order to survive. The Tok'ra try to get Earth to send Apophis back to where they found him, but they refuse. Angered over losing Apophis, Sokar starts to dial in and use a Particle accelerator to heat up the Iris with the intention to melt it so he can invade Earth. The wormhole is only able to be held open for thirty-eight minutes and during that time, Stargate Command personnel using liquid nitrogen to try to cool down the iris to little use. When that time is up, the SGC tries to dial out, but Sokar dials in first and continues his attack. Knowing that even if he fails to penetrate the iris, he will likely send ships to attack, it is decided to dial back to PB5-926 when the wormhole shuts down and send Apophis back through, stopping medical intervention at the same time so that Apophis will die. As Sokar is at war with Heru'ur, this will be enough to stop the attack. As the attack continues, Apophis' weakened condition allows his host to surface and Dr. Daniel Jackson comforts him. Apophis regains control and begs for a new host, admitting that he's afraid before dying, but the host remains alive for a little longer. Jackson promises to do the funerary rites of his culture so he can move on and the host dies too. Thanks to Captain Samantha Carter speeding up the dialing process, the SGC is able to dial out before Sokar can dial back in and Apophis' body is sent through the Stargate back to PB5-926. This is enough to make Sokar stop his attack as even though Apophis is dead, he has a sarcophagus and can revive him.

Hathor's Capture of SG-1
On a mission, the rogue Goa'uld System Lord Hathor captures all of SG-1 except Teal'c who she leaves badly wounded and takes them to her base where she has them placed in stasis. Three weeks later, she releases them and has her First Prime Trofsky and Raully, who is really a Tok'ra operative, pretend its seventy years in the future using a mock-up of Stargate Command inside her base. At the same time, Teal'c recovers from his injuries and travels to Chulak to gather reinforcements to try to rescue his team. There he finds a badly injured Bra'tac and starts the beginning of the Jaffa Rebellion. Colonel Jack O'Neill grows suspicious of what is going on and escapes, searching Hathor's base and rescuing Captain Samantha Carter and Dr. Daniel Jackson before searching for a way out. They are recaptured by Hathor who plans to implant O'Neill with a Goa'uld symbiote, but is stopped by Raully when he tries to kill it under the pretense of stopping his attempt to kill it. Meanwhile, SG-3 encounters the Tok'ra who give them the location of Hathor's base and Major General George S. Hammond organizes a rescue mission made up of all the SG-3, 5, 6 and 11. At Hathor's base, she straps O'Neill into a cryogenic tank and implants him with the Goa'uld, but Raully secretly puts him into stasis, which prevents the blending and kills the Goa'uld before Hathor discovers her and severely injures her with a Kara kesh. Carter and Jackson are rescued by the rescue team, but SG-3, who are guarding the Stargate, are captured and the rescue team is cut off from the Stargate by a giant shield and Sentry gun posts. The attack kills a few members of the rescue team, but blasts a hole into Tok'ra tunnels which the survivors escape into. Hammond, getting worried about the team, dials the planet and makes radio contact with them and after learning their situation, promises to send reinforcements in six hours while the team plans to take out the shield. Carter heads off armed with explosives to try to locate the generator while Jackson and the rest of the team are captured by Hathor's Jaffa. Carter finds Raully who tells her how to release O'Neill, which she does, but she is found by Hathor who starts to kill her with a hand device before O'Neill recovers and throws Hathor into the super-cool cryogenic fluid, killing her. The two find out from Raully that the shield generator is hidden behind the fake Stargate in the SGC mock-up and head there to plant explosives on it. At the same time, Hammond is unable to get authorization to send more men to rescue those already captured and travels to Chulak himself to get help from Teal'c and Bra'tac. The three uncover a Needle Threader hidden by Bra'tac to give them an advantage over Hathor's forces and prepare their attack. Near the Stargate, Trofsky uses his captives to try to draw Carter out and O'Neill decides to pretend to be possessed by the Goa'uld to trick him. Trofsky quickly sees through it and refuses to give up even when learning of Hathor's death. As soon as the Stargate starts dialing, Carter blows the C-4, taking down the shield and O'Neill shoots Trofsky. The Needle Threader comes through first, piloted by Teal'c and Hammond and destroys one of the Sentry gun posts. Bra'tac and several rebel Jaffa arrives and Bra'tac kills Trofsky, who survived O'Neill's attack thanks to his armor, with a staff weapon blast. After Hammond destroys the other attack tower with the Needle Threader's cannons, Bra'tac gets Hathor's few remaining Jaffa to surrender, ending the fight.

Seth's Infiltration of Earth
After Earth rebelled against the Goa'uld and buried the Stargate, the Goa'uld Seth was left trapped on Earth with no way off of the planet. Over the next several thousand years, Seth survived by using a sarcophagus or changing his hosts every four hundred years or so and started a cult in his name throughout various parts of history, controlling the members with the drug Nish'ta and forcing them all to commit suicide or murdering them when the authorities got too close, hiding also from the System Lords and the Tok'ra, both of whom wanted him dead. In 1999, the Tok'ra mapped out where all of the known Goa'ulds were and realized since they had no record of Seth after the burial of the Earth Stargate, that he was likely hiding out on Earth. Selmak, wanting to push his host Jacob Carter to fix his relationship with his son Mark Carter, volunteers for the mission and the two enlist the help of SG-1. Dr. Daniel Jackson searches Earth history for false religions in the name of Seth, figuring that he would create one to have power and followers and found his cults throughout history. After running a search on the United States Government classified net to see if the CIA had anything on Seth, he located Seth's current cult just north of Seattle, Washington on the ATF page as the ATF were investigating him because of his massive compound and all of his weapons. His current cult had about fifty members and deprogrammed members described him having Goa'uld abilities including the signature glowing eyes. SG-1 and Jacob investigate the compound, getting close thanks to the help of Jason Levinson who's son Tommy Levinson is a member of the cult. There they find out that among other powerful weapons, the followers carry Zat'nik'tels, confirming their suspicions of there being a Goa'uld there. However, the group is captured by ATF agents led by Special Agent James Hamner. Hamner reveals that he plans to try to force Seth to surrender and is annoyed when the team refuses to cooperate and tell him anything, although he does allow them to call Major General George S. Hammond. Hammond gets the President of the United States involved and the President personally calls Hamner and puts Colonel Jack O'Neill in charge of the operation. Going by Seth and other Goa'ulds mode of operation, the group realizes that there must be an emergency escape tunnel and with the help of the ATF forces, locate the entrance. Having figured out that Seth must be using Nish'ta to control his followers and knowing that an electric shock will break the Nish'ta's hold, Captain Samantha Carter sets herself, Jackson and O'Neill up with earpieces that can deliver and electric shock while leaving Jacob and Teal'c behind as Seth will be able to sense their symbiotes. The three enter the tunnels and are brought into the compound by Transportation rings where Seth gives them Nish'ta. After they wake up, he detects that Carter used to be blended to a Tok'ra and starts questioning them, forcing Jacob and Teal'c to shock them before they're sure its been enough time. Hamner, believing them to be compromised, surrounds the compound with his men while Seth orders SG-1 killed. The three manage to overpower the disciple ordered to kill them and shoot him with his own zat, freeing him from the Nish'ta. He reveals that he is Tommy Levinson and helps the three find more Zats which SG-1 is able to use to free Seth's followers who are preparing to blow themselves and the compound up. Tommy is able to transport Carter and the disciples down to the escape tunnels where they make their way out to be met by Hamner and his men, but Seth and his remaining followers corner Jackson and O'Neill. The two Zat the followers, but Seth's Kara kesh protects him with an energy shield and he knocks the two out before setting a bomb near them and escaping wearing one of his follower's cloaks. The two recover in time to escape while Jacob, armed with a Kara kesh of his own, enters the tunnels to confront Seth. Selmak finds Seth, but is injured by him before he can kill him. Selmak, who is able to heal his injuries but needs time, gives Carter his hand device, telling her she needs to use it to stop Seth. Carter confronts Seth, and despite having never used it before, manages to blast Seth down before he can blast her. Carter then blasts Seth with it again, crushing his midsection into the ground hard enough to create a small crater and killing him.

Saving Alternate Earth
An alternate reality Dr. Samantha Carter and Major Charles Kawalsky flee their reality to ours using the Quantum Mirror. There they ask for sanctuary from their world as it has been overrun by the Goa'uld System Lord Apophis. While they are originally allowed to stay, Dr. Carter begins to experience entropic cascade failure due to the presence of two Samantha Carters in one reality and in order to prevent her death, SG-1 must free her world from the Goa'uld. They decide to contact the Asgard of her world for help and the two Carter's are able to make the power booster device Colonel Jack O'Neill made while the Repository of Knowledge was in his brain work again so they can dial the Asgard galaxy. After Dr. Daniel Jackson finds the right reality in the mirror, Dr. Carter, Kawalsky, O'Neill, Teal'c and Jackson travel there while Major Samantha Carter from the correct reality remains behind. Once they arrive, they are forced to deactivate the mirror to prevent detection. Following the Jaffa, they find Apophis himself arriving through the Stargate and catch the alternate Teal'c's attention and lead him back to the storage closet where the mirror is. While Teal'c tries to get the alternate Teal'c to join them, he believes in the Goa'uld and Teal'c is forced to kill his alternate self. Teal'c then takes on alternate Teal'c's role as Apophis' First Prime and leads Dr. Carter to the Stargate Operations room where Apophis is torturing Major General George S. Hammond for the Stargate address to the Beta Site. Teal'c pretends to take over the interrogation as Apophis leaves and sends the other Jaffa with him. As they start to set up to dial the Asgard homeworld, a Goa'uld Ha'tak lands on top of Cheyenne Mountain. Teal'c and Dr. Carter are able to successfully set up the new dialing program created by O'Neill while he had the knowledge of the Ancients and O'Neill sets up the generator in the power room, causing the Stargate to dial the Asgard homeworld. As Hammond pretends to be a prisoner, Teal'c distracts a Jaffa that goes after Dr. Carter, allowing her to escape through the Stargate. However, as a result, Apophis becomes aware of Teal'c's betrayal and captures Teal'c and Hammond. Returning to the storage closet, O'Neill and Kawalsky find Jackson captured and are forced to surrender to spare his life. They are taken before Apophis who threatens Hammond's life to force them to tell him how O'Neill is alive, having been killed in that reality and who Teal'c is. When Apophis doesn't believe them, he has Hammond killed. However before Jackson can be shot more than once with a Zat'nik'tel, an Asgard mothership arrives and Apophis orders his troops to flee through the Stargate. As he goes to kill the prisoners, the mothership beams him and two Jaffa with him away and the Ha'tak retreats. Apophis' remaining Jaffa retreat through the Stargate and the invasion ends. The Asgard also beam away the alternate Hammond briefly and return him resurrected along with Dr. Carter. In the aftermath, with the alternate Earth saved, O'Neill, Jackson and Teal'c return home where their Major General George S. Hammond has the mirror destroyed.

Skirmish on Medieval planet
SG-1 travel to a Medieval planet where they find an ill young woman named Mary chained up. Believing they are demons come to take her, a young man named Simon begs them not to take her and to take him instead. As they treat Mary for what they believe is chickenpox, what the villagers believe to be a demon shows up and is revealed to be a Goa'ulded Unas in service to Sokar who demands five sacrifices for Sokar to use as hosts. SG-1 decides to kill the Unas and then have the villagers bury their Stargate, believing that as the planet is seemingly years away from any known Goa'uld homeworld by ship, they won't bother to come back that way for revenge. When the Canon returns, he uses his ring to knock out SG-1 believing them to be evil. Teal'c is subjected to The Tests and when he fails, he is drowned. As a result of Teal'c's passing the test, the Canon decides to let SG-1 go and they convince Mary and Simon to come with them. However, Teal'c comes back to life having been sustained by his symbiote and the Canon declares the team evil and makes them and Mary the next sacrifices. When the Unas returns, SG-1 and Mary are taken but briefly escape. The Unas catches them again, but Simon arrives with their gear and Teal'c's staff weapon. Simon shoots the Unas three times with the staff weapon but fails to kill it and is forced to run. SG-1 are able to use the staff to free themselves from the chain. While the others head to the Stargate, Colonel Jack O'Neill and Teal'c go after Simon who is knocked out after running into the Canon who the Unas goes after next. When O'Neill and Teal'c arrive, they find the Unas dead, the Canon unharmed and Simon knocked out. The Canon claims that the Unas died before it could harm him and Teal'c realizes that the Unas' wounds were too severe for even its Goa'uld to heal. O'Neill, Teal'c, Simon and the Canon meet up with the others at the Stargate where Major Samantha Carter starts to dial Earth but due to being a host to Jolinar of Malkshur is able to sense that the Unas' Goa'uld went into the Canon when its old host was dying. The possessed Canon attacks and O'Neill is forced to shoot him. The Goa'uld dies and the Canon lives long enough to beg forgiveness. Afterwards SG-1 return to Earth and Simon and Mary agree to bury the Stargate.

Rescue of the Abydonians
The Rescue of the Abydonians was an engagement between the forces of Goa'uld Amaunet and the Tau'ri on P8X-873 in 1999. Amaunet had traveled to the planet Abydos and kidnapped a group of Abydoians, including Kasuf, Sha're's father and brought them to P8X-873. Stargate Command sent SG-1 and another SG team to the planet to rescue the Abydonians from captivity.

During the attack, Colonel Jack O'Neill, Major Samantha Carter and the other SG teams held off the Jaffa. At the same time, Dr. Daniel Jackson ran to the tent and tried to save Sha're from Amaunet's control but failed and got stuck in Amaunets Kara kesh to his head. Teal'c found him and was forced to kill her with his Staff weapon.

Skirmish of Netu
Knowing that Sokar was gaining massive power, the Tok'ra sent Jacob Carter/Selmak to infiltrate his ranks and learn the size of his forces and his plans. Though Jacob was successful, learning that Sokar's forces were ten times what they believed them to be and that he was planning an attack on the System Lords that he'd win, Jacob is captured and imprisoned on Sokar's hellish prison moon Netu which was ruled by the Goa'uld Bynarr and his First Prime Naonak. Knowing that Jacob's information at the very least needed to be retrieved, the Tok'ra sent Martouf to enlist the help of SG-1, especially Major Samantha Carter, the last host to Jolinar of Malkshur, the only person to ever escape Netu. The group used a Tel'tak to travel to Netu where all of SG-1 (except Teal'c) and Martouf travel to Netu's surface in escape pods. There, the group is captured once Carter identifies herself as a former host to Jolinar and are reunited with Jacob who passes on his information to Teal'c through a Short range communicator. Carter is taken to see Bynarr and finally remembers how Jolinar escaped: she seduced Bynarr (who Carter deduces truly loved her) and then stole his key to the secret Transportation rings in his quarters which she used to escape to the planet Delmak (which Netu orbited) and stole a Tel'tak there. Bynarr goes to kill her to get some revenge on Jolinar, but is killed from behind by Naonak with a staff weapon. Using the distraction of the uprising coming from Bynarr's death, the team tried to escape through the Transportation rings to Teal'c's ship, but were captured by Naonak who revealed himself to really be Apophis. At the same time, Teal'c was forced to flee the system after being cornered by two Death Gliders and hearing a message from Apophis and returns to Vorash to alert the Tok'ra and get some help for a rescue. The Tok'ra, disturbed by the information of Sokar's forces, come up with a plan to kill him: they know he'll take his Ha'tak into Netu's orbit to put down the uprising before attacking the System Lords so they plan to launch a weapon into Netu's core that will destroy the moon and Sokar's ship, killing him. Meanwhile, Apophis tortures the team for information, but only gets a false location for the Tok'ra from Martouf before Sokar arrives and Apophis convinces him to make him Lord of Netu while really planning to assassinate him and take his place. Teal'c and the Tok'ra Aldwin arrive and Aldwin launches the weapon against Teal'c's wishes, starting Netu's destabilization which will take twelve minutes. The team manages to use the explosions to escape from their cage and make their way to the rings while Apophis boards Sokar's ship and tries to assassinate him, but fails as Sokar conquered the planet the Tok'ra supposedly are on. Netu's impending destruction allows Apophis to break free and shoot Sokar, but Sokar's personal shield protects him and Apophis flees. SG-1, Jacob and Martouf manage to make it to the rings which Martouf successfully hotwires and they ring aboard the Tel'tak once Teal'c gets into position. Netu explodes, destroying Sokar's Ha'tak and killing Sokar, but Apophis manages to use the ship's rings to escape to Delmak where he takes over control of Sokar's vast forces, restoring Apophis to a position of power once again.

Goa'uld Invasion of Tollana
Using the Triad of Klorel as a pretense, the Goa'uld Underlord Zipacna has his Jaffa paint the Tollans Ion cannons as targets for a Ha'tak he claims is there to pick him and Klorel up once the Triad is over. After the Triad doesn't go in the Goa'uld's favor with Klorel being ordered to be removed from Skaara by the Tok'ra, Zipacna uses a Goa'uld Long range visual communication device to signal the Ha'tak to attack before escaping through the Stargate himself. The Ha'tak destroys all of the Ion cannons and it and Death Gliders attack the defenseless Tollan, but Teal'c had been suspicions of Zipacna and had Lya of the Nox hide one of the Ion cannons. Using the hidden cannon, Teal'c destroys the Death Gliders and Ha'tak, ending the attack. Soon afterwards, Klorel is extracted from Skaara who is finally set free.

Attack on Kheb
In his search for the Harcesis child Shifu, which Sha're hid on the legendary planet Kheb, Apophis sends an assault force to the planet. SG-1 and the Jaffa eventually gets into a stand off, both sides unwilling to bow to the other. The Kheb Monk, saying they are not welcome, is shot and killed by the Jaffa. Suddenly, Dr. Daniel Jackson arrives and tells SG-1 and the Jaffa to drop their weapons, because using them would anger Oma Desala, the ascended being who is guarding the temple. SG-1 surrenders, but before the Jaffa can execute them, a bolt of lightning shoots from the clouds above and kills off all the Jaffa. The monk's body meanwhile vanishes in a bright light (he also ascended). Then, Oma appears in her Ascended form and carries the Harcesis through the Stargate to destinations unknown.

Osiris' return on Earth
Sarah Gardner opens a stasis jar and releases Osiris who takes her as a host. After killing three people, Osiris tracks Dr. Daniel Jackson, Major Samantha Carter, Dr. Janet Fraiser and Dr. Steven Rayner to the tomb in which the Osiris jar was originally found and dons the garb of his queen Isis as he is now in a female host and badly beats Steven before attacking the team. Osiris defeats Carter and Fraiser and tortures Jackson for information on Isis and the other Goa'uld and is pleased to learn of the deaths of Hathor, Seth and Sokar. As Osiris tortures Jackson, he manages to inject her with a powerful sedative, causing her to weaken. Unable to fight further, Osiris activates an Archaic Tel'tak and activates a set of Transportation rings. Carter shoots at Osiris, but the rings block the shots and Osiris escapes to her ship and flees the planet.

Cronos' Invasion of Juna
Some time after the People of Juna rebel against Heru'ur and bury their Stargate, Cronus arrives in his ship and takes over the planet, unburying the Stargate. As the Naquadah mine is dry it is theorized he likely did it for strategic reasons. After Cronus' takeover, the robot Colonel Jack O'Neill, Teal'c, Major Samantha Carter and Dr. Daniel Jackson arrive on an exploratory mission and are captured by the people of Juna and a Jaffa, led by Darian, but the robot O'Neill manages to escape. That night he captures Darian and his wife Hira and tries to explain to them the truth about him and his team and after learning how Cronus took control of the planet, tries and fails to convince them of the truth about Cronus and Heru'ur so he leaves. The next day, Cronus returns in his ship and is pleased to learn of the capture of what he believes to be SG-1. Cronus holds a gathering attended by the warriors of Juna and robot O'Neill disguised as a Juna warrior. As a reward for his loyalty, Cronus orders Darian to kill robot Jackson and has his Jaffa hold the people hostage to force him to do so. Robot Jackson signals robot O'Neill not to interfere and Darian blasts robot Jackson with a Staff weapon, decapitating and "killing" him, but shocking everyone including Cronus as it reveals his true nature as a robot. Meanwhile, Harlan comes to Earth worried about the robot team as they are overdue and gives the real team (minus the real Dr. Daniel Jackson who is on a mission) the location of the planet they went to. As Stargate Command dials the gate and sends a MALP, robot O'Neill takes out the Jaffa guarding the gate and uses the MALP to communicate with Earth. He is joined by Darian who, after seeing Cronus' reaction, came to realize that he is not a god after all and wants to help. After learning of the situation, SG-1, minus Jackson travel to the planet. On his ship, Cronus orders his Goa'uld scientist Ja'din to find out how the robots work and she "tortures" robot Carter and Teal'c for information on how the deactivated power pack on robot Jackson works. At the same time the real team comes up with a plan: use the Transportation rings in the Pyramid to reach the ship with the plan to travel to the Pel'tak (the bridge) and seal off the other levels to keep the Jaffa out while they kill Cronus and then offer the Jaffa freedom. On the ship, after being contacted by robot O'Neill, robot Teal'c offers a deal in exchange for robot Carter's freedom, but instead uses the opportunity to attack Cronus, overpowering one Jaffa and killing the other with his staff weapon before shooting Cronus who uses his Kara kesh's shield to block it, causing robot Teal'c to start strangling him. Robot O'Neill is taken by Darian to see Sindar, pretending to be a prisoner before the two attack, killing Sindar while the rest of the team enters and helps take out the remaining Jaffa, but robot O'Neill is badly damaged by a staff blast. Robot Carter tells Ja'din how to reactivate the power pack, but in reality tricks her into activating a Self-destruct that kills her and frees robot Carter, who takes out the Jaffa guarding the rings and transports up the team, leaving behind robot O'Neill and Darian. Teal'c rushes to the Pel'tak where robot Teal'c is shot in the back and mortally damaged by another Jaffa who Teal'c shots with a Zat'nik'tel then uses as a shield to try to no avail to shoot Cronus before Cronus shoots both the Jaffa and Teal'c, killing the Jaffa and wounding Teal'c, allowing Cronus to begin crushing Teal'c's symbiote to painfully kill him. Robot Carter, Major Samantha Carter and Colonel Jack O'Neill travel to a circuit breaker to close the area off and robot Carter pulls the crystals as its protected by a force field, getting electrocuted the whole time while O'Neill and Carter cover her. Robot Carter successfully pulls the crystals and closes off area, but "dies" from the damage she sustained doing it. On the Pel'tak, Cronus continues trying to kill Teal'c, but robot Teal'c manages to grab a staff weapon and shoots Cronus in the back with it three times, killing him and saving the real Teal'c. Robot Teal'c "dies", proclaiming he did it for his and real Teal'c's father Ronac who Cronus had killed in the same way he tried to kill Teal'c. The invasion ends and SG-1 ends up capturing Cronus' ship, but robot O'Neill "dies" of the damage he sustained from the staff blast and his power running out. With Cronus dead, O'Neill has Darian get any people who believe that still believe Cronus is a god so they can be shown Cronus' body as proof that he's not.

Skirmish on Memphis
During a mission to Memphis to check out intelligence received from the Tok'ra on the Goa'uld building a base there, SG-1 comes across Tanith and are forced to flee to the Stargate chased by Death Gliders and Tanith himself in an Al'kesh. Colonel Jack O'Neill, Major Samantha Carter and Teal'c (armed with a Staff cannon) guard Dr. Daniel Jackson as he dials the Stargate and everyone but Teal'c rush through it after it opens. Teal'c, upon seeing Tanith in the cockpit of the Al'kesh, waits until it gets closer and then uses his staff cannon to destroy the cockpit, killing Tanith and causing the ship to crash into the Dial Home Device as Teal'c escapes through the Stargate, cutting the wormhole off in transit. Eventually, Teal'c is rescued from the Stargate and shares the good news of Tanith's death with the team.

Goa'uld invasion of Steveston Oregon
After Dr. Richard Flemming and Dr. Peter Stofer of Immunitech Research cloned a Goa'uld, there was a lab accident and Flemming was taken as a host and Stofer disappeared. Because the symbiote was immature they were only able to control the host while they were asleep. Flemming proceeded to infest the majority of the population of Steveston, Oregon and began building a ship to escape the planet. Flemming realized what was happening and contacted Major Samantha Carter but was run off the road and killed in a car crash. SG-1 minus Colonel Jack O'Neill traveled to Steveston and began investigating. They searched Flemming's house and accepted a package containing a syringe that was sent from Flemming. The next day, Jonas Quinn noticed several of the residents behaving strangely and that the shipyard had seen recent activity despite it's closure several months ago. After breaking in to the shipyard, they discovered the ship and realized they townspeople were infested with Goa'uld. That night Teal'c and Jonas staked out the warehouse and were detained by NID Agents Cross and Singer. They explained that they have been monitoring the situation for three months and are waiting for the Goa'uld to complete the ship. At the hotel, Carter discovered the syringe contained an antibiotic designed to kill the symbiote and injected herself before the townspeople kidnapped her and implanted her with a symbiote. When Cross realized the situation was out of control he radioed a containment team, but Singer had been taken as a host and shot the three of them with a Zat'nik'tel. Luckily, Carter's symbiote died shortly after implantation and she was able to stop Cross and Singer from infecting the NID and call in backup. The townspeople were then treated with the antibiotic and the event was covered up.

Ba'al's capture of O'Neill
After Colonel Jack O'Neill was infected with an Ancient contagion and was implanted with a Tok'ra named Kanan, he disappeared from a Tok'ra base and traveled to Ba'al's outpost. He attempted to rescue Ba'al's lo'taur Shallan but was captured by Ba'al's Jaffa after Kanan fled his body. He was revived in a Sarcophagus and questioned by Ba'al. He insisted he did not know why Kanan came to his planet. Ba'al tortured him to death several times and revived him with the Sarcophagus. While in his cell, O'Neill was visited by an ascended Dr. Daniel Jackson who offers him ascension but O'Neill refused and asked him to help him escape but Jackson could not interfere because it was against the rules. Eventually, SG-1 figured out what Kanan was up to, but the outpost was too heavily fortified for an attack. Knowing that he was unable to help directly and that all O'Neill needed was a fighting chance, Jackson planted the idea in Teal'c's mind that if they informed another System Lord about the outpost which Ba'al had kept a secret, they would attack with a Ha'tak and it could be used as a distraction for O'Neill to escape. The SGC informed Lord Yu-huang Shang Ti, asking that he target the power generators first. Yu attacked, knocking out the generators first as asked, allowing O'Neill to escape his anti-gravity cell after Jackson let him know what was happening and overpower the Jaffa guarding him. Following Kanan's last wish, O'Neill took Shallan with him and they managed to escape to Earth in the chaos of the attack.

SG-1's rescue from Her'ak
While babysitting a group of scientists on P5X-112, SG-1 was captured by Her'ak and taken aboard a Ha'tak. Two of the scientists, Dr. Jay Felger and Dr. Simon Coombs, ringed up to the Ha'tak to rescue them. Colonel Jack O'Neill explained that they were captured on purpose to meet with an undercover Tok'ra named Khonsu. O'Neill had the undercover Rebel Jaffa Dol'ok hide them on the ship. After arriving on Khonsu's World, Her'ak killed Khonsu because Anubis knew of his true identity for some time and used him to capture SG-1. Dol'ok and another rebel Jaffa were also killed but Felger and Coombs were not discovered. Felger realized something was wrong and took their armor and ringed down to the planet. They snuck into the Pyramid and made their way to the control room. They were able to deactivate the forcefield in SG-1's cell and Coombs directed them out of the pyramid from the control room. When the reached the Stargate, SG-1 was able to take out the Jaffa but Coombs was cut off from the ring room. O'Neill had Coombs ring himself and Teal'c into the pyramid and they took out the Jaffa blocking Coombs exit. The three of them ringed back to the gate and they escaped back to Earth.

Skirmish on P3X-367
After SG-4 returned from P3X-367 with Alebran, they informed SG-1 that Nirrti was experimenting on the People of P3X-367. After Alebran became sick and died from cellular breakdown, SG-1 and SG-4 traveled to 367 and took out the Jaffa guarding the fortress. Once inside, they discovered the inhabitants had been severely altered with Wodan possessing Telekinesis and Eggar possessing Telepathy. They explained that Nirrti had cured them of a disease and that they were expecting her back soon. Jonas Quinn and Teal'c went with Wodan to the basement and were attacked and imprisoned. Colonel Jack O'Neill and Major Samantha Carter stayed to study the machine. When O'Neill lost contact with SG-4, he went to investigate and Nirrti ringed into the room and shot Carter with a Zat'nik'tel. When O'Neill returned, he tried to shoot one of Nirrti's Jaffa but Wodan stopped the bullet in midair. Nirrti then imprisoned the two with Jonas and Teal'c. Nirrti then placed Lt. Colonel Sergei Evanov in the DNA resequencer and Nirrti manipulated his DNA. When she was done she returned him to the cell and did the same to Carter. When she moved on to Jonas, she told him that she could give him great power but he told if she did he would use them to kill her. Back in the cell, Evanov died of cellular breakdown. After Jonas refused to join her, Nirrti brought O'Neill to machine. On the way O'Neill was able to convince Eggar to read Nirrti's mind. When they entered the room, Eggar read her mind and discovered that she was not a god. He informed Wodan that she killed Alebran and Wodan used his power to break her neck but not before Eggar was able to learn how to work the machine. Eggar used the device to reset Carter and themselves before destroying it.

Skirmish on P4S-237
When the inhabitants of P4S-237 requested assistance in defeating the Goa'uld Mot, Colonel Jack O'Neill, Teal'c and SG-15 went to the planet to set up an ambush. During a meeting with the village leader Ellori, Chazen used a Shock grenade to stun them and informed Mot. Mot tried to set a trap by allowing Natania to free the prisoners and ambush them at the Stargate to get access to Stargate Command. Luckily, Jonas Quinn used his Precognition to warn them by radio. The warning was heard by Chazen who sounded the alarm. Mot attempted to kill Chazen but was shot by Natania. Because the alarm was sounded, the team was able to avoid the ambush and kill the Jaffa at the gate. They traveled back to the SGC and assembled SG-3 and 10 as reinforcements before returning and defeating the remaining Jaffa.

Skirmish of P5S-117
In order to stop the Avenger virus, Major Samantha Carter and Dr. Jay Felger traveled to P5S-117, the planet where the virus was sent by Stargate Command in the first place. There they learn that Ba'al upgraded the virus and spread it to the Stargate Network in order to gain more power due to his vast fleet. Unfortunately, this means the anti-virus program they brought would have to be modified. While Felger works on fixing the anti-virus, the two are found by a Jaffa patrol and Carter gets into a firefight with them to buy time. The two are nearly overrun, but Colonel Jack O'Neill and Teal'c arrive in an Al'kesh and drive off the Jaffa. Afterwards, Felger successfully brings an end to Avenger and makes it so the virus can never be used again.

Ambush of Anubis' supersoldier
After Teal'c and Bra'tac were attacked by Anubis' new Kull warrior, SG-1 minus Dr. Daniel Jackson, SG-3 and Bra'tac set up an ambush on Ramius' homeworld with the help of the Rebel Jaffa hiding in Ramius' Jaffa. When the Kull warrior came through the Stargate and headed towards the Pyramid, Major Samantha Carter trapped it in a Tok'ra shield and Colonel Jack O'Neill shot it with a Tranquilizer gun but it had no effect. The supersoldier then escaped the shield and killed three Jaffa and wounded Colonel Albert Reynolds and other members of his team. O'Neill then ordered the detonation of the A-M18A1 Claymore mines and C-4 but the supersoldier was unharmed. It proceeded to the pyramid and the team was captured by Ramius' Jaffa. They are placed in a cell until the supersoldier attacks the pyramid and kills Ramius. They are then released by the Jaffa guarding them. Carter and Teal'c steal a Tel'tak and use the Transportation rings to bring the supersoldier aboard and vent the atmosphere to knock it unconscious and bring it back to Earth.

Tau'ri attack of Tartarus
After capturing a Kull warrior and using a Tok'ra memory recall device to learn the location of its homeworld of Tartarus, Major Samantha Carter, Teal'c, and Bra'tac took a Tel'tak to the planet and hide behind one it's moons while Jacob Carter used the Kull armor to get pass the Stargate shield and enter the facility. Jacob was stopped by Thoth and placed in a machine for repairs but Thoth was pulled away by Anubis and Jacob was able to deactivate the sensors and let them in the base. They began to search and discover a Queen that was preparing to spawn thousands of symbiotes with no genetic memory to brainwash them to serve Anubis. They plant C-4 to ensure the Queen is not allowed to spawn again and continue the search. They come upon a large room where Anubis is addressing several hundred supersoldiers and they are discovered by Thoth. Carter shoots him and the alarm sounds. They detonate the C-4 and head for the Tel'tak. They are chased by several supersoldiers and one is able to board the Tel'tak. It It attacks them but Bra'tac is able to ring it outside the ship.

Skirmish with Osiris
Osiris comes to Earth using an Al'kesh and beaming technology with plans to probe Dr. Daniel Jackson's mind with a memory recall device while he is asleep for the location of the Lost City of the Ancients, believing that the location is buried in his subconscious from the time when he was Ascended. Osiris pretends to be her host Sarah Gardner, but deviations from how he remembered things alert Jackson to something not being right and the team realize what must be going on and come up with a plan: they will allow Osiris to probe Jackson's mind one last time in an attempt to learn the location for themselves, but will use new jamming technology to block her ability to beam out. After she finishes, they will use a tranquilizer gun which they know can penetrate her shields and knock her out so the Tok'ra can remove Osiris from Sarah and save her. Eventually, Jackson realizes he never knew the location of the city and Osiris tries to kill him, but is attacked by Colonel Jack O'Neill and Teal'c, but shoots them with her Kara kesh them and tries to beam out. Osiris is unable to beam out to her frustration and heads outside where she engages Major Samantha Carter and Pete Shanahan in battle, but they are unable to penetrate her shields and she blows up the surveillance van containing the jamming equipment with a Zatarc ring, severely wounding Pete. Before Osiris can do more, a recovered O'Neill tranquilizes her from behind. Osiris is removed by the Tok'ra and presumably killed and Sarah is finally set free from the hell she had to live through for the past three years.

Anubis' attack on the Alpha Site
After Anubis learned the location of the Alpha Site, he launched an attack. The Stargate was hit by an Al'kesh and several Kull warriors landed in Tel'taks. Major Samantha Carter and Jacob Carter were there working on the Kull disruptor when the attack began. Lt. Glenn came to inform them that Colonel Reilly ordered an evacuation. As Carter and Jacob were downloading the data onto a crystal before deleting it Glenn was shot in the back by a supersoldier. Jacob managed to kill it with the disruptor and they both headed into the forest as the self-destruct was set off by Reilly. Jacob was caught in the explosion and a tree fell on his leg while Carter was chased into the forest by a supersoldier. SG-1 and SG-3 came to search for survivors and discovered Jacob who gave them the disruptor and told them Carter had a full power unit. Dr. Daniel Jackson went back to Stargate Command with Jacob while Colonel Jack O'Neill and Teal'c went to search for Carter. Major General George S. Hammond sent out an Unmanned Aerial Vehicle with missiles but it was shot down by the supersoldier. Carter was able to make her way to the crash site and fire the missile at the supersoldier but it did not kill it. Luckily, O'Neill and Teal'c arrived and Teal'c was able to draw the supersoldiers' attentiton so O'Neill could get the new power unit and kill it.

Skirmish on P3X-666
On a standard exploration mission of Ancient ruins on P3X-666, SG-13 came across a Goa'uld Reconnaissance probe. After a brief fire fight, they were able to neutralize it with a Colt M203 grenade launcher, but not before it sent out a sub-space signal informing Anubis of what had happened. Deeming the world to be safe, at least for the immediate future, Stargate Command allowed SG-13 to continue to study the ruins they had found with SG-3 as backup. However, Major Samantha Carter soon realized that the probe had sent out a sub-space signal. Moments after SG-13 received this message, Anubis' forces had already arrived on the planet. With Senior Airman Simon Wells subsequently injured via staff weapon blast, Colonel David Dixon sent Dr. Cameron Balinsky back to the SGC for reinforcments. Major General George S. Hammond sent several SG teams including SG-1, SG-3, and SG-5 to extract them while Dr. Janet Fraiser stabilized the wounded Wells. When they arrived on the planet, they were immediately faced with an army of Jaffa and several Al'kesh. Taking cover in the ruins, they were able to hold of the Jaffa while Janet tended to Wells. With the help of Dr. Daniel Jackson, the man was quickly stabilized, but not before Janet herself was hit by a staff blast and was killed instantly. Meanwhile, Colonel Jack O'Neill was shot in the torso by a staff weapon, however, the wound was not fatal due to the new vest inserts. After the battle, a memorial service for Janet was held where Carter read the names of those who, instead of having given their lives for their country, were still alive and serving due to Janet's excellent care. Among the many lives saved by Dr. Fraiser, and listed by Teal'c and Carter at Janet Fraiser's memorial service, was the whole SG-1 team, Wells, Major Ian Hules and Sgt. Connie Smith.

Skirmish of P3X-439
The Goa'uld System Lord Anubis sent a Reconnaissance probe to the planet P3X-439 to scout, which discovered the secrets the planet held. SG-1, SG-3, and SG-5 arrived first in an attempt to extract the information from the Ancient Repository of knowledge but were stopped by the arrival of Anubis' fleet. Flanked by Death Gliders and Al'kesh, SG-1 destroyed the Repository of knowledge with C-4 after Colonel Jack O'Neill took the drastic step of interfacing with the device, and downloading the Ancient knowledge into his brain. The three SG teams then escaped back to Stargate Command through the Stargate.

Anubis' infiltration of the SGC
While working to adjust the orbit of the International Space Station to avoid a piece of debre from Anubis' fleet, Cosmonaut Anatole Konstantinov was possessed by Anubis. He returned to Russia and became ill. He was visited in the hospital by his friend Russian Air Force Lt. Colonel Alexi Vaselov and Anubis left Konstantinov for Vaselov because of his recent assignment to Stargate Command. After Vaselov arrived at the SGC, he requested permission to join SG-1 but was denied by Brigadier General Jack O'Neill. Vaselov was visited by Dr. Daniel Jackson and Anubis entered his body. After Vaselov was taken to the infirmary and Dr. Brightman discovered lesions on his body, O'Neill stopped Anubis in Jackson's body from going through the Stargate. Anubis then took a hostage and shot two guards before Teal'c shot him with a Zat'nik'tel and O'Neill shot him in the shoulder with his sidearm. After Jackson was taken to the infirmary, Anubis left his body for Lt. Evans. When Jackson regained consciousness and discovered that Anubis was responsible, he remembered Anubis leaving his body for Evans. After Evans was detained, it was discovered that Anubis had left her body as well. After O'Neill ordered blood tests for all base personnel to check for elevated white blood cell counts, Airman Malcolm McCaffrey missed his test. They began a search and Anubis attempted to flee through the gate but O'Neill shot him with a Zat and Anubis left McCaffary and went through a wall. In order to force Anubis to use his ascended powers and alert the Others, O'Neill put the base in a three section lockdown. After several days under lockdown, O'Neill was ordered by President Henry Hayes to resume normal operations. O'Neill made a fake announcement that the lockdown would be held indefinitely to force Anubis to act. Anubis in the body of Lt. Colonel Samantha Carter bypassed security and set up a program to dial the gate. On his way to the gate he was shot with a Zat by O'Neill and left Carter for O'Neill. Anubis then tricked Major Kearney into setting the self-destruct before shooting him with a Zat. Anubis headed to the Embarkation Room and waited for his program to dial the gate but was stopped by Vaselov and convinced to leave O'Neill for Vaselov before entering the gate. Luckily, Carter was able to change the address to KS7-535 and Anubis was frozen solid on the other side.

Skirmish on P2X-887
After one of Anubis' former Jaffa gave intel on a base on P2X-887, Brigadier General Jack O'Neill sent SG-1 and SG-3. Lt. Colonel Samantha Carter ordered SG-3 to guard the Stargate while SG-1 searched for the secert base. After activating the Transportation rings, SG-1 was unable to get out of the base. Meanwhile, an Al'kesh flew over the gate and Colonel Albert Reynolds contacted Stargate Command for reinforcements to search for them. When the teams returned and reported no sign of SG-1, Ba'al contacted the SGC and said he had captured SG-1. He offered their release in exchange for Camulus. After O'Neill released Camulus, SG-1 dialed in from 887 and informed O'Neill that they had been traped in the base and not captured by Ba'al but were attacked by Ba'al's Jaffa on their way to the gate. They were able to fight off the Jaffa and head back through the gate.

Moloc's attack on the Hak'tyl
During a meeting of the Rebel Jaffa in Moloc's army, Moloc came to Hak'tyl ll himself in order to wipe out the resistance. All were killed except Teal'c, Ishta and Aron whom Teal'c did not trust. During the night Ishta is captured by Moloc's soldiers and tortured by Moloc himself. Teal'c shot Aron with a Zat'nik'tel as he could not trust him. After Stargate Command sent an Unmanned Aerial Vehicle and it was shot down, Teal'c located the crashsite and retrieved the Tretonin and laser designator but was surrounded by Jaffa. Luckily, Aron arrived and helped Teal'c kill the Jaffa. Teal'c launched a rescue mission for Ishta while Aron uses a laser designator to designate two missiles sent by the SGC onto Moloc, killing him and his Jaffa. Teal'c takes out all of Moloc's remaining Jaffa on the planet and comes into contact with Moloc's First Prime, Cha'ra, who is using Ishta as a hostage. He shoots him with a Zat and knocks him out (who later joins the Jaffa Rebellion) and successfully rescues Ishta.

Goa'uld attack on Prometheus
After the Prometheus is hijacked by Vala Mal Doran in an attempt to sell it to the Lucian Alliance for weapons grade Naquadah, Dr. Daniel Jackson is able to take back the ship but unable to stop the ship from finishing its course to its destination. The ship lands on a planet where Tenat and Jup are waiting for Vala. When she does not show but Jackson in her stead they are still willing to go through with the trade, which he turns down. When suddenly several Death Gliders start to fire on the unshielded Prometheus. Jackson shots the two mercenaries with a Zat'nik'tel and gets to the ship in order to escape but needs Vala's help in order to unlock the systems, and together they engage the several Death Gliders and Al'kesh, but they run out of weapons and their shields fail before they can take them all out. Then the Al'kesh controlled Lt. General George S. Hammond and the crew of the Prometheus comes in and helps finish off the remaining forces. Both ships quickly escape before they have to engage a nearby Ha'tak mothership. After the battle Vala is able to escape on the Al'kesh.

Ares' attack on Arkhan's World
The Goa'uld Ares decides to return to and take over the planet where Harold Maybourne used to live on so he sends his First Prime, Trelak and some ground troops as an advance party and comes himself in his mothership. SG-1 is already on the planet and is attempting to get the people to leave, but they believe that the Goa'uld will be defeated and refuse to go. Trelak recognizes Teal'c and Dr. Daniel Jackson among the villagers and sends men to find Lt. Colonel Samantha Carter, who along with Brigadier General Jack O'Neill, are trying to a get a Time Jumper they found working again. They barricade themselves inside and when Carter gets power hooked up, take off and fly into space to confront Ares' mothership. The distraction caused by the Jumper flying overhead allows Jackson and Teal'c to take the offensive and together with the help of Garan, they kill all of Ares' Jaffa and Trelak. In space, the Jumper comes up against the mothership which fires at them but misses. O'Neill fires two Drone weapons at it but after that the Jumper's weapons are depleted. Luckily, the drones hit some vital systems and the mothership is destroyed, killing Ares.

Goa'uld Infiltration of the Trust
After the Stargate was recovered by the Prometheus and The Trust Al'kesh fled to hyperspace, the Trust agents in it attack a few more Goa'uld worlds and are captured by an unknown Goa'uld. They are implanted with Goa'uld's and sent back to Earth to implant the rest of the Trust. As part of a plan to cause a nuclear war to destroy Earth so they can presumably get control of the Antarctic outpost in Antarctica, the Trust use an agent to implant Russian General Miraslov Kiselev with a Goa'uld and also implant former Vice President Robert Kinsey. Stargate Command becomes aware of their plan somewhat due to Kinsey warning Brigadier General Jack O'Neill that the Trust are planning something. Dr. Daniel Jackson travels to Russia to try to figure out what's going on while the Trust send the Goa'uld-Kinsey to pretend to attempt to assassinate Kiselev so the Russians believe the Americans have been compromised by the Goa'uld. While all of this is going on the Prometheus conducts an unsuccessful search for the Trust's Al'kesh. Jackson is detained and checked for a Goa'uld before being shown Kinsey who is now a prisoner. Meanwhile the Kremlin stops taking calls from President Henry Hayes due to fear he has been turned into a Goa'uld. Working with Russian Colonel Chekov, Lt. Colonel Samantha Carter and O'Neill attempt to stop the threat. Carter figures out Kiselev is a Goa'uld and Chekov manages to get O'Neill a direct line to the Russian President Mikhailov through friends of his in an attempt to convince him of the truth. In Russia, Jackson goes to see Kinsey and as one of the Trust's agents goes to detain him, manages to escape with Kinsey by activating a locator beacon, signaling the Prometheus to beam him on board. In a desperate attempt to destroy the ship, the Trust Al'kesh launches an attack on the Prometheus while its shields are down, doing some damage. Prometheus raises shields and starts to battle the Al'kesh while Kinsey manages to escape and rings to the Al'kesh. In the SGC, Carter, O'Neill and Chekov try to convince Mikhailov of the truth, and while he does hear them out, he's reluctant to believe them even when sent evidence as he's worried they may be compromised as well. They lose the connection just as Kiselev attempts to launch a nuclear attack without authorization. On the Al'kesh, Kinsey kills Jennings, the Trust agent piloting it and possibly beams away. The Prometheus shields hold under the onslaught from the Al'kesh at 40% and the ship gets an opportunity to destroy the Al'kesh with Jennings' death as the Al'kesh is defenseless. Colonel Lionel Pendergast, the ship's commander, is reluctant to fire but gives the order when the Al'kesh powers up again. Prometheus fires two missiles and destroys the Al'kesh, possibly killing Kinsey. On Earth, it looks like Russia and the US are about to go to nuclear war, but the Russian President apparently decides to believe O'Neill and stops Kiselev who is presumably arrested and the situation is defused. Presumably, Kiselev and the known Trust members in Russia are then freed from their Goa'ulds, although much of the Trust is still infected with Goa'ulds.

SG-1 Stranded Ancient Egypt
After using the Time Jumper to travel back in time 5,000 years to ancient Egypt to steal a Zero Point Module, SG-1 meets Katep and Salatis. They joined them on a pilgrimage to Ra's temple to make an offering. When Ra was displeased with the offering, he ordered his Jaffa to kill Salatis. After Ra left SG-1 shot a Jaffa with a Zat'nik'tel and Teal'c took his Jaffa helmet and armor to gain access to the treasure room. Teal'c is able to retreive the ZPM and they head back to the Jumper but it had been covered up by a sandstorm and was discovered by Ra's Jaffa. Despite Brigadier General Jack O'Neill wanting to retake the Jumper, Lt. Colonel Samantha Carter would not allow them to as it would change the timeline. After several years of gathering weapons and tying to recruit people to start a rebellion, there attempts were discovered and O'Neill, Teal'c and Carter were exacuted. Dr. Daniel Jackson was able start the rebellion over again and it succeeded in expelling Ra from Earth but he took the Stargate with him causing an alternate timeline.

Alternate Earths Chulak Skirmish
After the timeline was changed due to SG-1's involvement, the alternate timeline versions were able to find the Beta Gate in Antarctica and use the Time Jumper that was uncovered in Giza, Egypt to travel to Chulak. Once through the gate, Colonel Jack O'Neill landed near and city and he, Dr. Daniel Jackson, Dr. Samantha Carter, Major Charles Kawalsky and Senior Airman Jake Bosworth head towards the city. On the way, they are stunned by a Goa'uld Shock grenade and taken prisoner. After trying to convince Teal'c to join them, Jackson is taken to Apophis who impants him with Goa'uld symbiote to be used as a spy. Teal'c brings them their gear and Carter shows him the camcorder video of his alternate self. Jackson is then returned to the cell and they use C-4 to escape. On the way back to the Jumper, Teal'c is waiting for them and kills Jackson. They head to the Jumper and take off but Kawalsky, Bosworth, Donner, and Mansfield are killed. Once in the air, O'Neill uses the ship to time travel to avoid the Death Gliders that were chasing them.

Alternate Earth in Ancient Egypt
After travel back in time on Chulak, Colonel Jack O'Neill, Dr. Samantha Carter and Teal'c head through the Stargate to Earth. They head into the nearest village and are greeted by Katep. He takes them inside so they are not seen by a Jaffa patrol. Once inside, Dr. Daniel Jackson enters and shows them the hidden weapons cache. They then begin to plan an attack that ensures the gate does not get taken by Ra and Carter works to fix the Time Jumper's cloak. While she is working, the Jumper is discovered by Ra's Jaffa and Teal'c and Jackson bring the villagers to help rescue them. Later, the rebellion is successful and Ra leaves without the Stargate.

Ba'al's infiltration of the Trust
After the Battle of Dakara, Ba'al sought refuge on Earth and took control of the The Trust. When Gerak of the Free Jaffa Nation discovered this, he sent troops to Earth and attacked a Farrow-Marshall Aeronautics warehouse in Edison, Virginia. He was able to capture a Goa'uld inside of Alex Jameson but was of his Jaffa was left behind and hit by a car and killed. After Teal'c and Lt. Colonel Cameron Mitchell traveled to Dakara to confront Gerak, he denied any knowledge of the Jaffa's presence but Teal'c believed he was lying. Lt. Colonel Samantha Carter Dr. Daniel Jackson began investigating Farrow-Marshall but Carter was stonewalled by Charlotte Mayfield. Teal'c and Mitchell began asking around Dakara and Ka'lel informed them that the Jaffa died attempting to capture Ba'al. After the Goa'uld inside of Alex Jameson was tortured into giving the location of Ba'al's hideout, a group of Jaffa lead by Yat'yir raided an office building by Ba'al was able to escape. Following the attack, Ba'al sent a message to Stargate Command and told them he would follow Earth laws if he was left alone and had placed a Naquadah bomb in a building in the United States of America that he would detonate if another attempt on his life was made. After Agent Malcolm Barrett and the NID discovered Ba'al's location, Carter and Jackson joined him on a stackout. When Ba'al went public by having a news conference announcing his purchase of Hammel Technologies, Major General Henry Landry called off the assignation to avoid a media circus. After Ba'al returned to a Trust facility, Landry ordered an attack on the facility with Symbiote poison but the Trust was able to intercept the transmition and Ba'al activated the bomb in a building in Seattle, Washington. After the building was evacuated, Mitchell had the Prometheus beam the building into space. Meanwhile, Landry launched the symbiote poison but Ba'al was not there. Teal'c went to Dakara to talk to the Jaffa High Council when Gerak brought in Ba'al and exacuted him. Teal'c returned and the rest of the team informed him that cloning technology was found in the facility.

Khalek's attack on the SGC
When SG-1 finds an Ancient lab on P3X-584 formerly controlled by Anubis, they have no choice but to explore, they find a DNA resequencer of Ancient design and a stasis pod containing a young man. The young man is released from stasis and taken to Stargate Command. He tells them his name, Khalek, and that he was a captured by a Goa'uld. But all this was a rouse which is later found out by Dr. Daniel Jackson after searching the logs in the lab. He was in fact the son of Anubis, half Human and half Goa'uld, and possessing the entire Genetic memory of Anubis before his ascension and a genetically advanced body on the verge of ascension. He was designed to be a foot soldier capable of ascending and taking over the ascended planes from the Ancients in an attempt to not only control the galaxy but the entire universe. But SG-1 was able to stop their plan. They plan to hold Khalek in a specifically designed room to contain such a hostile and dangerous creature to stop him from getting any more treatments from the manipulation machine to stop him from ascending and either put him in stasis or kill him. Richard Woolsey arrived and informed Major General Henry Landry that the International Oversight Advisory has decided to not put him in stasis but study him in an attempt to find a way to fight the Priors of the Ori. When Major Altman hooked up the Ascendometer to Khalek, Khalek overloaded a monitor injuring Altman and tried to escape but was shot by Lt. Colonel Cameron Mitchell. After Landry overruled the IOA and was about to send Khalek back to 584, Jackson returned and informed him that Khalek needed more time in the machine so 584 is the last place he should be sent. Khalek used his advanced hearing to listen in and was able to escape. He proceed to the Embarkation Room and headed back to 584 through the Stargate. Fortunately, Lt. Colonel Samantha Carter reset the Call forwarding device to send him back to the SGC. As he returned through the gate, Mitchell was able to distract him long enough for Jackson to shoot him and together they shot him several times, killing him. Because of their encounter with Khalek they were able to construct a weapon capable of disabling advanced mental powers for a temporary time, this helped in their victory in fighting the Ori.

Trust attempt to destroy Atlantis
Due to transmissions picked up from members of The Trust, Agent Malcolm Barrett of the NID alerts Stargate Command of a Trust plan to destroy Atlantis on the next scheduled dial-in through a planted bomb. The SGC manages to make contact with the Daedalus which is on route back to Earth by sending an SG-5 to P4M-399 and warns them of the plan so they can relay the message to Atlantis. The Daedalus, pushing its hyperdrive to the limits, manages to get into range of Atlantis and warn them just in time of the threat, stopping the dial-in at the last second. The Daedalus is recalled to help with the investigation while the team looks for the operative who they believe to be human as he's supposed to be a low-level member of the Trust. Due to the suspicious activities of Dr. Peter Kavanagh, he becomes the prime suspect in the case. At the same time, the NID raids a Trust compound and finds computers with some further intelligence on the plan. They don't learn much as the data is cryptic, but they do learn that there's no transmitter on Earth to detonate the bomb, that its something on the Atlantis end that will cause the bomb to detonate. Dr. Rodney McKay discovers that the city's Zero Point Module failsafes had been disabled and that dialing Earth would have caused the ZPM to overload and explode. In order to reverse this, the command code of the person responsible is needed. The city's systems have also been programed to help this happen, trying to dial Earth which is unsuccessful due to the Stargate's control crystal being removed while at the same time broadcasting a brief distress message with Atlantis' transmitter to draw two nearby Wraith cruisers in order to force the city to be cloaked to give it another opportunity for an overload. When the city cloaks, the program activates the inertial dampeners which, combined with the cloak, cause the ZPM to start to overload. With no other choice and unable to use the Stargate, the Daedalus and the city's Puddle Jumpers take the expedition to the Light Bugs' Planet, the nearest inhabitable planet in the Lantean system. Seeing no other option, Dr. Elizabeth Weir reluctantly agrees to let Ronon Dex torture the information out of Kavanaugh, but he faints before Ronon can start. At the same time, Lt. Laura Cadman discovers two deletions in the city's records with Colonel Steven Caldwell's command code attached. The team quickly stops Ronon's attempt to torture Kavanaugh and have Hermiod beam Caldwell to Atlantis' conference room to be questioned. Upon being confronted by the evidence, Caldwell reveals that he is actually a host to a Goa'uld Trust agent who is the one doing the sabotage. The Goa'uld refuses to give up the command code so Lt. Colonel John Sheppard Tasers him, injuring the Goa'uld and allowing Caldwell to regain control of his body at least temporarily. Caldwell, although in a lot of pain from the Taser and his fight for dominance against his Goa'uld, manages to give Sheppard the code he needs and McKay enters it, shutting down the Trust program and reinitializing the failsafes, averting disaster. Hermiod is later able to use the Daedalus' beaming technology to remove the Goa'uld from Caldwell and it is presumably killed afterwards. Caldwell survives the extraction and returns to his position as commander of the Daedalus.

Earth/Jaffa Attack on Ba'al's Stronghold
After Teal'c is captured by a Ba'al clone for brainwashing, a rescue is set up after Bra'tac follows the brainwashed Ka'lel to P2M-903 where Ba'al had a Ha'tak parked on a pyramid and was trying to brainwash Teal'c. There, several SG teams including SG-1 and SG-3 battle Ba'al's Jaffa soldiers including a fixed Staff cannon emplacement, backed up by Bra'tac piloting an Al'kesh. Bra'tac's Al'kesh is shot down by Death Gliders and Bra'tac is captured. Lt. Colonel Cameron Mitchell manages to take out the staff cannon with a grenade launcher and makes it to the pyramid's Transportation rings. Lt. Colonel Samantha Carter and Dr. Daniel Jackson save Mitchell from some Jaffa and then ring him into the ship while staying behind to defend the position from the Jaffa which were retreating as they were getting overrun by the Tau'ri forces. On board Ba'al's Ha'tak, Teal'c is apparently successfully brainwashed and is brought an injured Bra'tac to execute with a staff weapon to prove it, but Mitchell, after shooting every Jaffa he came across with a Zat'nik'tel, makes it to the room and attacks, taking out the guards while Teal'c who is revealed to have been faking all along, shoots the Ba'al clone three times with the staff weapon, killing him. Realizing someone is still piloting the ship and that it is taking off, Mitchell, Teal'c and Bra'tac quickly make their way to the rings and escape before the ship leaves. On Dakara, a vote establishes a democaracy for the Free Jaffa Nation and Ba'al's brainwashing over the Jaffa High Council members is broken, fully ruining his plan.

Ba'al's Takeover of the SGC
Ba'al comes to Earth in an Al'kesh and is shot down by an F-16 near Cheyenne Mountain. SG-1 meet Ba'al at the crash site and he tells them that the clones are rebelling. Stargate Command starts to round up the clones to receive the information they believe Ba'al possesses, the location of Merlin's weapon. Several teams including SG-1 collected several Ba'al clones by fighting their way through Jaffa. Finally all the clones are gathered at the SGC but unknown to the SGC the Ba'als brainwashed Agent Malcolm Barrett into breaking procedure giving them the chance to escape and take over the SGC. The clones take control of Level 15, 16 and 17 and take Barrett and Lt. Colonel Samantha Carter hostage. Lt. Colonel Cameron Mitchell, Teal'c and Vala Mal Doran each lead a strike team to provide a distraction so Dr. Bill Lee and MSgt. Sylvester Siler can release Symbiote poison throughout the levels. Meanwhile, Ba'al forced Carter to download the entire database of Gate addresses form the SGC computer in the hopes of finding the planet with Merlin's weapon and not only destroy the Ori but the Ancients as well. After Vala's team is discovered, Lee is forced to release the poison early and the clones have time retreat back to one location and use their locator beacons to penatrate the SGC's jamming signal and beam to a Tel'tak in orbit.

Athena's Capture of Vala
During a dinner with Dr. Daniel Jackson at Il Fiore Bianco, Vala Mal Doran is kidnapped by Devon of The Trust. She is brought to a warehouse where Athena had Weaver and Kakalios use a Memory recall device to find the location of the Clava Thessara Infinitas in Qetesh's memories. During a rescue attempt, the device used to stimulate Vala's memory was hit with a Zat'nik'tel and Vala lost her memory. Vala wandered into Sol's Diner and tried to leave without paying the bill but the owner Sal stopped her. She explained that she could not remember anything from before entering his diner and he gave her a job as a waitress. During one of her shifts, she stopped two men from robbing the diner and was taken to the police station to give her statement. Detective Ryan questioned her and she gave him a fake name so he sent out an attempt to identify bullitin. This got the attention of Stargate Command and The Trust. Unfortunately, The Trust was able to get there first and an impostor of Lt. Colonel Samantha Carter took her away. SG-1 showed up at the station shortly after and Lt. Colonel Cameron Mitchell chased the car on a Motorcycle. While in route she was able to cause the car to crash and Mitchell came upon the crash. Mitchell was shot by one of the Trust operatives and Vala stole a man's car and made Mitchell drive to a hotel room. After Vala left the hotel, she was cornered in a warehouse by The Trust but SG-1 was able to find her and Jackson was able to help her regain her memories.

Ba'als capture of Adria
After SG-1 used the Galaran memory device to implant false memoried into Vala Mal Doran and lure Adria to an unnamed planet, Ba'al stole Adria off them by beaming several battalions of loyal Jaffa to take her away. Ba'al later killed most of his clones and their Jaffa with Symbiote poison to make sure his plan was not ruined by them and their egos. He then implanted Adria with a clone while in the meantime SG-1 beamed aboard to retrieve Adria unknown to them it was actually Ba'al in control. They were successful in reaching Adria/Ba'al by killing several Jaffa and a Ba'al clone. But they soon realized it was not Adria but Ba'al. They devised a plan to swap Ba'al out for a Tok'ra but this plan failed when Ba'al released his symbiote toxin into her system in attempt to kill her so that the Tok'ra could not retrieve the knowledge she possessed. Ba'al was extracted but not soon enough for Adria to take over the Odyssey before she Ascended.

Alternate Reality Skirmish of the Achilles
In the Alternate Reality Skirmish of the Achilles, Ba'al uses the Solar observation outpost on Praxyon to travel back in time to 1939 through the Stargate to change time using a solar flare. The Achilles is an ocean freighter captained by Mitchell (Colonel Cameron Mitchell's grandfather), that is carrying the Alpha Gate from Africa to the United States of America before the outbreak of World War II. At the time it was zig-zaging across the North Atlantic to evade U-boats and was near the North Pole. Ba'al and three Jaffa arrive and the activation of the Stargate vaporizes the Bosun. Ba'al has his Jaffa kill the entire crew of the ship despite their best attempts to escape and fight back and then plants a Naquadah bomb to destroy the Stargate in order to stop the Tau'ri from being able to stop him in the future. The entire crew is killed and Captain Mitchell is mortally wounded by the time that Ba'al and his Jaffa escape through the Stargate leaving behind the activated bomb. The Captain manages to toss the bomb overboard through the hole made by the activation of the Stargate where it detonates harmlessly in the ocean, but he dies at some point later and the Achilles becomes trapped in the ice of the North Pole leaving the US without a Stargate in the future.

Skirmish on Praxyon
Colonel Cameron Mitchell, Dr. Daniel Jackson, Colonel Samantha Carter, the alternate Teal'c and two Jaffa travel to the planet Praxyon through the Stargate recovered by the Russians. Once there, Carter realizes that the facility that they gated into is Ba'al's time machine and that they can use it to set things right. After convincing Teal'c of this, Carter sets to work to find the right solar flare to send them back in time while Mitchell, Jackson, Teal'c and the two Jaffa work together to hold off Qetesh's Jaffa that keep ringing in. Carter finds a solar flare that will send them back to 1929, ten years too soon, but they decide that it will have to be close enough. Jackson and the two Jaffa are killed in the battle and Carter is killed as she finishes dialing the Stargate. Mitchell escapes through the Stargate into the past, but Teal'c is mortally wounded by the remaining Jaffa and remains behind. Qetesh rings in and offers Teal'c to become her First Prime, but as his last act before dying, he detonates a grenade that kills him, Qetesh and the enemy Jaffa and destroys the time machine.

Skirmish of the Achilles
The Skirmish of the Achilles is a skirmish on the ocean freighter Achilles between Colonel Cameron Mitchell and the ship's First Mate, Bosun, against Ba'al and three Jaffa. In order to change the timeline, the real Ba'al travels back in time to destroy the Achilles and the Alpha Gate before it can reach the United States of America. But Colonel Cameron Mitchell managed to travel back in time from the altered future caused by this to 1929 and after waiting for ten years, he somehow manages to stow aboard the Achilles and is prepared to stop Ba'al. When Bosun comes to check out the cargo due to the Stargate causing vibrations, he runs into Mitchell who he mistakes for the Captain Mitchell who is Cameron's grandfather. Mitchell hands him a Thompson submachine gun and orders him to one side of the Gate so he won't be vaporized by its activation like he was in the alternate timeline. The first two Jaffa come through the Stargate and are immediately killed by Mitchell and the Bosun. Ba'al comes through next and is shocked to see Mitchell who shoots him in the head, finally killing him. The last Jaffa arrives carrying the Naquadah bomb and is killed by the Bosun, putting history back on track as Ba'al and his men are now never able to stop the Achilles from reaching the United States with the Stargate.
