Spartan-IIIs Kat-B320 and Jun-A266 were from New Harmony. Sometime in the first half of 2537, prior to July 27th, a battle took place on this planet between Covenant and UNSC forces. The UNSC successfully defended the planet and won a rare naval victory. During the battle, a prowler, the UNSC Razor's Edge, managed to attach a telemetry probe to a retreating Covenant frigate, allowing it to track the ship and locate K7-49.
