The Siege of Atlantis: Defense in Depth Across a City

The Siege of Atlantis was a defense-in-depth campaign fought across orbit, ocean, airspace, and the corridors of an Ancient city. An approaching Wraith fleet first encountered the restored defensive satellite, which destroyed one hive before being lost. Atlantis then relied on orbital mines, Puddle Jumpers, railguns, drones, transported nuclear weapons, Marine reinforcements, and the city shield to delay the remaining attackers. This episode examines how each layer imposed costs without offering a permanent solution. Wraith darts and boarding forces carried the battle inside the city, while depleted power and irreplaceable ammunition narrowed the expedition’s options. The arrival of Daedalus introduced fresh firepower and a Zero Point Module, but additional hives made a decisive fleet victory unlikely. Atlantis survived through a final layer of deception: cloaking the city and simulating its nuclear destruction. Defense in depth succeeded because no single failed system was allowed to become the end of the battle. Visit ImaginedBattlefield.com for more military and science fiction.
