The Battle of Kolm-an was the last great battle of the Four Years War between the United Federation of Planets and the Klingon Empire. It was fought on reference stardate 1/9803.20 at the planet Kolm-an in Klingon space, and led to a final victory for the Federation.
On stardate 1/9712.06, Klingon Admiral Komex surrendered himself to Federation authorities and revealed the locations and importance of two major Klingon bases, including Kolm-an, where Klingon defenses were apparently centered. (FASA RPG modules: The Klingons: Star Fleet Intelligence Manual, The Klingons: Game Operation Manual) During the initial Klingon invasion early in the Four Years War, it had been a major control center and command post, coordinating communications and acting as a forward marshaling area. (FASA RPG module: The Orions: Book of Common Knowledge) It later became a significant supply and repair base. (FASA RPG modules: The Klingons: Star Fleet Intelligence Manual, The Klingons: Game Operation Manual) However, it was really not as fortified or defended as other bases had been. (FASA RPG module: The Orions: Book of Common Knowledge)
- The Orions: Book of Common Knowledge depicts the Kolm-an base as an administrative base, while The Klingons mentions its importance to supply and repair. It is possible that the base's role expanded or changed during the war.
Armed with this information, Starfleet launched Operation Argus Redoubt against Kolm-an. (FASA RPG modules: The Klingons: Star Fleet Intelligence Manual, The Klingons: Game Operation Manual) In the Battle of Kolm-an on stardate 1/9803.20, Starfleet forces made a massive assault against the world. The lightly fortified Kolm-an base was overrun and ruined by victorious Starfleet forces.
Its loss shattered Klingon supply and repair capabilities. The Klingons could do nothing to organize a defense against Federation forces, so the Empire was forced to sue for peace.
