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.

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 Hammond, and made O'Neill as her new First Prime, once she implants him with a Symbiote. However, Teal'c and all the women members of the SGC had managed to have stopped Hathor. However, she escapes through the Stargate. The only known casualties were Teal'c, and Janet Fraiser, who were shot by influenced SFs.

Skirmish on P4A-771
When SG-1 arrived to P4A-771 they came under fire from Goa'uld staff weapons. They were surrounded so Daniel Jackson quickly dialed the gate for they could retreat back to Earth. Daniel and Teal'c made it through with O'Neill and Carter a little behind them. Right as they were about to go through one of the alien's energy blasts hit the gate. This caused Daniel and Teal'c to be launched out of the gate at the SGC at such a force it rendered Daniel 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 General 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 alien energy blasts. Due to this Hammond ordered they that would not attempt to return to the planet for a rescue mission.

Skirmish on Nassya
The planet Nassya is under Goa'uld attack and SG-1 tried help a group of local Nassyans on the planet Nassya flee through the Stargate from the attack on their world, Captain Carter stops to give CPR to a fallen villager. He suddenly grabs her head, and a Tok'ra symbiote possesses her, and she becomes hunted by a Zatarc on Earth

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. Ultimatly Apophis returns and leaves with Amaunet, having been falsely told by Amaunet that Heru'ur has the child. Heru'ur himself then rings down into the pyramid and faces off against SG-1 with his personal shield protecting him, but after O'Neill throws a knife through his shield and into his hand device, disabling it, Heru'ur retreats to his mothership and leaves the planet alone.

Hathor's Capture of SG-1
On a mission, the rouge 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 the SGC 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 begining of the Jaffa Rebellion. Colonel Jack O'Neill grows suspisous of what is going on and escapes, searching Hathor's base and rescuing Captain Samantha Carter and Doctor 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 General Hammond organizes a rescue mission made up of all the SGs 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 severly injures her with a hand device. Carter and Daniel 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 two attack towers. The attack kills a few members of the rescue team, but blasts a hole into Tok'ra tunnels which the survivors escape into. General 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 and 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, General 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 possesed 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 C4, taking down the shield and O'Neill shoots Trofsky. The Needle Threader comes through first, piloted by Teal'c and General Hammond and destroys one of the attack towers. 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 General Hammond destroys the other attack tower with the Needle Threader's cannons, Bra'tac gets Hathor's few remaning 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, volunteers for the mission and the two enlist the help of SG-1. Doctor 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 eye glow. SG-1 and Jacob investigate the compound, getting close thanks to the help of Jason Levinson who's son Tom is a member of the cult. There they find out that among other powerful weapons, the followers carry zats, confirming their suspisions 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 General Hammond. Hammond gets the President involved and the President personally calls Hamner and puts 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, Carter sets herself, Daniel 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 a ring transporter 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 comprimised, surronds 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 Tom 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. Tom 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 Daniel and O'Neill. The two zat the followers, but Seth's hand device 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 hand device 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.

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, also Kasuf Daniel 's father-in-law and brought to P8X-873. Stargate Command sent SG-1 and another SG team on the planet to rescue the Abydonians from captivity.

Stargate Command found out that the Goa'uld Amuanet had kidnapped a group of Abydonian by Abydos and taken them to the P8X-873 and kept them trapped in corral a piece from her tent. SG-1 and another SG team arrived at the planet and shooting at Jaffa soldiers liberated them while Abydonian and led them to the Stargate back to Earth again.

During the attack they lost two Tau'ri SG team members and it was close to Tau'ri would not lose the battle of Jack jump in a combat vehicle and shot at them Jaffa soldiers running down a hill towards them. At the same time was Daniel Jackson in the tent and tried to save Sha're by Amaunet's control but failed and got stuck in Amaunets Hara'kesh to his head. Teal'c found him and was forced to postpone Amaunet with its Ma'Tok staff on her, killing her.

Skirmish of Ne'tu
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 succesful, 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 Ne'tu 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, especialy Major Samantha Carter, the last host to Jolinar, the only person to ever escape Ne'tu. The group used a Tel'tak to travel to Ne'tu where all of SG-1 (except Teal'c) and Martouf travel to Ne'tu's surface in decent 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 communications device. 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 ring transporter in his quaters which she used to escape to the planet Delmak (which Ne'tu 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 ring transporter 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 Ne'tu's orbit to put down the uprising before attacking the System Lords so they plan to launch a weapon into Ne'tu'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 Ne'tu while really planning to assisinate him and take his place. Teal'c and the Tok'ra Aldwin arrive and Aldwin launches the weapon against Teal'c's wishes, starting Ne'tu's destablization 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 assisinate him, but fails as Sokar conqured the planet the Tok'ra supposedly are on. Ne'tu'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 succesfully hotwires and they ring aboard the Tel'tak once Teal'c gets into position. Ne'tu explodes, destroying Sokar's mothership 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.

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 monk of Kheb, saying they are not welcome, is shot and killed by the Jaffa. Suddenly, 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.

Skirmish in the Vorash System
When SG-1 acquired a Ha'tak after they killed Cronus, they planned to move their Tok'ra allies to a world without a Stargate, intending to take the Vorash Stargate with them. Tanith, however, sent a message to Apophis, who brought his fleet to attack the planet. Tanith was able to escape in an Al'kesh but was pursued by Teal'c and O'Neill in a Death glider and eventually the both of them were shot down, where on the planet, a firefight took place between several Jaffa where Jack is hit by a staff weapon but is eventual rescued by the Tau'ri controlled Ha'tak. After this, Jacob and Samantha Carter decided on a different course of action: after dialing P3W-451, they launched the Stargate into the sun, causing it to lose some of it's hydrogen and a supernova emerges. The plan worked, destroying Apophis' fleet, but causing the Tau'ri ha'tak and Apophis' mothership to travel four million light years into another galaxy.

Skirmish with Osiris
Osiris comes to Earth using an Alkesh and beaming technology with plans to probe Doctor Daniel Jackon's mind while he is asleep for the location of the the Lost City of the Ancients, believing that the location is buried in his subconcious 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 Daniel'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, the will use a tranquilizer dart which they know can penetrate her shields and knock her out so the Tok'ra can remove Osiris from Sarah and save her. Eventually Daniel realizes he never knew the location of the city and Osiris tries to kill him, but is attacked by Jack O'Neill and Teal'c, but beats them and tries to beam out. Osiris is unable to to her frustration and heads outside where she engages Samantha Carter and Pete Shanahan in battle, but they are unable to penetrate her shields and she blows up the survalence van containing the jamming equipment, severly 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.

Skirmish on P3X-666
In 2004, While 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, 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, the SGC allowed SG-13 to continue to study the ruins they had found. However, Major 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 one man subsequently injured via staff blast, General Hammond sent several SG teams including SG-1, SG-3, and SG-5 to extract them while Dr. Fraiser stabilized the wounded airman.

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 the wounded airman. With the help of Daniel Jackson, the man was quickly stabilized, but not before Janet herself was hit by a staff blast and was killed instantly. Meanwhile, Col. Jack O'Neill was shot in the torso by a Goa'uld Staff weapon, however, the wound was not fatal.

After the battle, a memorial service for Janet was held where Sam 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 Samantha Carter at Janet Fraiser's memorial service, was the whole SG-1 team, Airman Simon Wells, Major Ian Hewles and Sergeant Conny Smith.

Skirmish of P3X-439
The Goa'uld System Lord Anubis sent a reconnaissance probe to the planet to scout, which discovered the secrets the planet held. SG-1, SG-3, and SG-5 arrived first, narrowly missing the arrival of Anubis's fleet. Flanked by gliders and Al'kesh, SG-1 destroyed the repository after Jack O'Neill took the drastic step of interfacing with the device, by downloading ancient knowledge into his brain trough the |repository of the Ancients' knowledge.

Moloc's attack on the Hak'tyl
Moloc came to the Hak'tyl camp on a new world himself in order to wipe out the resistance. All were killed except Teal'c, Ishta and Arron whom Teal'c did not trust. Ishta is captured by Moloc's soldiers and tortured by Moloc himself. Teal'c launches a rescue mission for Ishta while Arron 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 who is using Ishta as a hostage. He zats and knocks out the First Prime (who later joins the Jaffa Rebellion) and successfully rescues Ishta.

Goa'uld attack on Prometheus
After the Prometheus is hijacked by Vala in attempt to sell it to the Lucian Alliance for weapons grade Naquadah, 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 Daniel 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. Daniel takes out the two mercenaries 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 Tau'ri controlled Al'kesh 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 Harry Maybourne used to live on so he sends his First Prime 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, Ares' First Prime, recognizes Teal'c and Daniel among the villagers and sends men to find Colonel Carter, who along with General O'Neill, are trying to a get a time-traveling Puddle 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 Daniel and Teal'c to take the offensive and together with the help of one of the villagers, 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 drones 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 Alkesh 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 Ancient weapon in Antarctica, the Trust use an agent to implant Russian General Kiselev with a Goa'uld and also implant former Vice President Kinsey. The SGC becomes aware of their plan somewhat due to Kinsey warning 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 Alkesh. Daniel is detained and checked for a Goa'uld before being shown Kinsey who is now a prisoner. Meanwhile the Kremlin stops taking calls from the President due to fear he has been turned into a Goa'uld. Working with Russian Colonel Checkov, Colonel Carter and General O'Neill attempt to stop the threat. Carter figures out Kiselev is a Goa'uld and Checkov manages to get General O'Neill a direct line to the Russian President through friends of his in an attempt to convince him of the truth. In Russia Daniel 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 Alkesh launches an attack on the Prometheus while its shields are down, doing some damage. Prometheus raises shields and starts to battle the Alkesh while Kinsey manages to escape and rings to the Alkesh. In the SGC Carter, O'Neill and Checkov try to convince the Russian President 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 Alkesh, Kinsey kills Jennings, the Trust agent piloting it and possibly beams away. The Prometheus's shields hold under the onslaught from the Alkesh at 40% and the ship gets an opportunity to destroy the Alkesh with Jennings' death as the Alkesh is defenseless. Colonel Pendergast, the ship's commander, is reluctant to fire but gives the order when the Alkesh powers up again. Prometheus fires two missiles and destroys the Alkesh, 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.

Khalek's attack on the SGC
When SG-1 finds an ancient lab formerly controlled by Anubis, they have no choice but to explore, they find a genetic manipulation machine of Ancient design and a stasis pod containing a young man. The young man is released from stasis and taken to the SGC. 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 Daniel. 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. their plan was 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 (it was never decided which was going to take effect as the IOA could never decide). But he was able to escape and reap havoc all over the base. As he attempted to escape through the Stargate Cameron Mitchell was able to distract him long enough for Daniel 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
After raiding a Trust stronghold, Agent Malcolm Barrett alerts Stargate Command of a Trust plan to destroy Atlantis on the next schelduled dial-in through a planted bomb. Stargate Command manages to make contact with the Daedalus 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 suspisious activities of Doctor Peter Kavanagh, he becomes the prime suspect in the case. Its discovered that the city's ZPM 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 unsuccesful 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 activate the inertial dampners 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 Jumper's to the Light Bugs' Planet, the nearest inhabitable planet in the Lantean system. Seeing no other option, Doctor Weir reluctantly agrees to let Ronon Dex torture the information out of Kavanaugh, but he faints before Ronon can start. At the same time, Lieutenant 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 Colonel John Sheppard tazers 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 tazer and his fight for dominance against his Goa'uld, manages to give Sheppard the code he needs and Doctor Rodney McKay enters it, shutting down the Trust program and reintializing 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 Deadalus.

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 bttle Ba'al's Jafa soldiers including a fixed staff cannon emplacement, backed up by Bra'tac piloting an Alkesh. Bra'tac's Alkesh is shot down by Death Gliders and Bra'tac captured, by Colonel Cameron Mitchell manages to take out the staff cannon with a grenade laucher and maes it to the pyramid's rings. Colonel Samantha Carter and Doctor Daniel Jackson save Mitchell from some Jaffa and then ring him into the ship while staying behind to defend the postion 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 apparentyly succesfully brainwashed and is brought an injured Bra'tac to execute with a staff weapon to prove it, but Mitchell, after zatting every Jaffa he came across, 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 High Council members is broken, fully ruining his plan.

Ba'al's Takeover of the SGC
A Ba'al clone 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. The SGC start 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. They downloaded the entire database of Gate addresses form the SGC computer and escaped in the hopes of finding Merlin's weapon and not only destroy the Ori but the Ancients as well.

Ba'als capture of Adria
After SG-1 captured Adria, 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 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 a 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 Observatory 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 Colonel Cameron Mitchell's grandfather that is carrying the Stargate from Africa to the United States before the outbreak of World War Two. 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 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 the Captain 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 reality 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, Daniel, 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. Daniel 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 Mitchell and the ship's Bosun against Ba'al and three Jaffa. In order to change time the real Ba'al travels back in time to destroy the Achilles and the Stargate before it can reach the United States. But Colonel 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 the Bosun comes to check out the cargo due to the Stargate causing vibrations, he runs into Mitchell who he mistakes for the ship's captain who is Mitchell's grandfather. Mitchell hands him a machine 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 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.
