Once again the self-destruct button has been activated and people all over the city seem to be falling at the hands of the Wraith, colonel Everett, Teyla and now also Ford, who falls into the water. Sheppard is the only hope, he's on a suicide mission to nuke one of the two remaining hive ships. Just about to launch the bomb, he gets a message that he needs to decloak. The Daedalus has arrived and the ship is equipped with powerful equipment from the Asgard, including beaming technology. Its commander, Colonel Steven Caldwell, beams Sheppard aboard before the nuke goes off. By beaming a nuke into the last remaining hive ship, Atlantis seems saved. Then Zelenka detects 12 more hive ships on their way. Meanwhile Ford has been found. He should be dead, but Beckett finds out he received an overdose of Wraith enzyme. He's now addicted to it and seems remarkably strong. Written by Arnoud Tiele (

Did You Know?


Hermiod's ill-tempered disposition has been compared by fans to that of Marvin the Martian from the Looney Tunes animated shorts, in stark contrast to other Asgard, which were portrayed as much more affable.. See more »


Boom from the nuclear explosion in space is heard at the same time as the first light is seen. There should not be a boom at all (space, remember?) but even if there were, it should arrive minutes later. See more »


Col. Steven Caldwell: Can we submerge the city again?
Dr. Rodney McKay: It's a city, not a yo-yo.

Part 3. Great!!
4 September 2007 | by JeffreyRexSee all my reviews

This episode is a great start, of season 2.

Not only is it much better,(In my opinion)than all of the episodes from season 1, but when i see this episode i think of the extremely good Stargate SG-1 episodes.

In the SG-1 seasons, it does just like Atlantis, for example season 1 ends so good(In my opinion)so the fans can't wait for the next season to begin.

This episode puts the greatest of SG-1, together with the Pegasus galaxy, the brilliant writers for this episode have done a good job.

Before this second season, i had a lot of questions about what was going to happened, after part one and part two of the siege, and this episode answers a lot of those questions, and keep you wanting for more.

The Siege Part 3-Watch it!!!!
