List of episodes

"The Siege" is the season finale for season one and season premiere for season two of the military science fiction television series Stargate Atlantis, and the nineteenth, twentieth and twenty-first episode of the series overall. The episodes were written by executive producers Joseph Mallozzi and Paul Mullie (part two) and Martin Gero (part one and three), and all three were directed by Martin Wood. The episodes were one of the series strongest in season 1 on Nielsen ratings and part three gathered the strongest rating with "Instinct" in season 2. The episode got strong reviews from major media publishers worldwide.

Part three introduced several cast changes for the season, including the departure of Aiden Ford (Rainbow Sun Francks) and the inclusion of Dr. Carson Beckett (Paul McGillion) and Steven Caldwell (Mitch Pileggi) to the main and recurring cast. "The Siege" is about the Wraith laying a siege on Atlantis and the Atlantis expedition's re-contact with Earth.
