Spoiler Alert, click show to read:

The Apollo launches an initial nuclear strike against the Replicators since they build actual cities and ships rather than using replicator blocks. In retaliation they send a beam weapon satellite to attack Atlantis directly. Because the city was left with only one ZPM, the shields will last against a sustained assault for a limited time. After submerging the city does little to slow down the shield drain, they're forced to take more drastic measures.

The mobile drilling station (From "Submersion") is hooked up to Atlantis to power the star drive while the X302s tow an asteroid to block the beam's path in order to buy enough time for the city to reach orbit and enter hyperspace. The plan works up until the last seconds when the weapon cuts through the asteroid and strikes the middle of the city as they escape. Dr. Weir was in the stargate control room when the blast hit and is presumed dead or critically injured. The damage to the city causes the star drive to give out and stops short of it's destination. Atlantis is left adrift in between solar systems and all remaining power is failing rapidly.
