Just before August 30, 2552, the UNSC Pillar of Autumn landed and was dry-docked in the ship-breaking yards. It was also one of the final sites that one could get off world.
On August 30, 2552, Emile-A239 and Noble Six escorted the AI Cortana through the ship breaking yards to be put on the cruiser the Pillar of Autumn. The ship graveyards underneath the main ship-breaking facilities were the site of a large battle. Once the Pillar of Autumn took off, Noble Six moved down into the ship breaking yards, for their final encounter with the Covenant before dying to multiple attacking Elites.
