The Siege of Atlantis was the first major Wraith offensive in nearly ten-thousand years, directed against the humans that had taken up residence in the abandoned Lantean stronghold of Atlantis. Fearing that the "Atlanteans" would take up the fight of their ancestors, and recognizing that their homeworld and its galaxy offered a rich, untouched feeding ground, the Wraith attacked in an attempt to take the city for themselves. After a lengthy campaign that spanned the entire star system before culminating on Lantea itself, the Atlantis Expedition forced a stalemate by faking a nuclear self-destruct, ensuring their continued survival against impossible odds.
