The Battle of New Harmony was an engagement between the United Nations Space Command and the Covenant Empire during the Human-Covenant war. This engagement was fought in-orbit or around the Human colony of New Harmony, and was one of the few UNSC naval victories of the war. 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. This subsequently led to the strategic, though costly, victory during Operation: PROMETHEUS.
