The Skirmish on Elson's planet was an event that took place in 2008 during the Tau'ri-Wraith war.
Prelude[]
Due to all survivors of the Hoffan drug being immune to feeding, the Wraith begin tracking down all survivors and killing them. They wipe out the Balarians homeworld and track the Balarians to another world that they relocate to with the help of the Atlantis expedition.[3]
Battle[]
A small group of Wraith arrives through the Stargate and offers the villagers a deal: hand over the Balarians and they'll leave the village alone, don't and they'll wipe out the village and all of the villagers. Teyla Emmagan and Ronon Dex plan to retake the Stargate, but more Wraith arrive from patrol so they are unable to do so. Jervis betrays the Balarians to the Wraith in an attempt to save himself and sends one group to the Wraith at the Stargate. Before he can send anymore he is stopped by Dr. Carson Beckett who manages to convince him to stop. In an attempt to save himself, Sefaris betrays Beckett to the Wraith and Beckett and Dr. Rodney McKay are captured by them and taken to the Hive ship which arrives in orbit. There, the Wraith Commander forces Beckett to complete his now dead scientist's work on detecting plague survivors. On the surface in order to protect the Balarians, they are taken to a nearby mine for protection while Lt. Colonel John Sheppard, Ronon and Teyla try to come up with a plan to help them escape. Beckett completes the scientist's work and tests himself for the drug. Learning that he has it (Michael Kenmore likely gave it to him as a defense against the Wraith), he tricks the Commander into feeding on him, killing the Commander. He takes the Commander's stunner and frees McKay. The two make their way to a console where they use the ship's communications system to communicate with Sheppard who orders them to disable the Hive ship's weapons as part of his plan. McKay does while Beckett covers him and then the two run off. On the planet's surface, Elson frees Jervis to make a deal with the Wraith and tells him where the remaining Balarians are located. On the Hive ship McKay and Beckett make their way to the Dart Bay but are unable to fly a Wraith Dart and Wraith start to blast through the door into the Bay. Jervis leads most of the Wraith into the mine where they find the Balarians gone and a block of C-4 which Sheppard detonates, killing the Wraith and Jervis and his men. With most of the Wraith killed in the mine, they are easily able to take the Stargate and start to evacuate everyone to Atlantis. The Hive ship tries to fire at them, but are unable to as McKay had disabled the weapons so the new Commander launches Darts to attack them. One tries to cull Teyla but instead deploys McKay and Beckett who beamed themselves into Dart storage and programed it to drop them off once they realized that the Darts were going to be launched.[3]
Aftermath[]
Everyone escapes through the Stargate and the Balarians and villagers are resettled on another planet.[3]
