Archanis Campaign
}}
The Archanis Campaign was a conflict between the United Federation of Planets and the Hunters of D'Ghor in 2399, primarily in the Archanis Sector territory held by the Federation. It began with D'Ghor raids against Federation colonies and Starfleet infrastructure, the region under-defended after over two decades of peace with the Klingon Empire. Starfleet responded by dispatching the 4th Fleet to bolster defences, provide humanitarian support to civilians, and pursue and eliminate the D'Ghor. After multiple weeks of operations, the D'Ghor launched a consolidated assault against key Federation systems, a surprise strike anticipated by Starfleet, who were reinforced by a strike team from the Klingon Defense Force. The ensuing Battle of Archanis was won by the KDF-Starfleet forces, with the D'Ghor forces decimated and the leader Kuskir, son of D'Ghor, captured.
While lone raiders may remain in the sector and the campaign has left the region devastated and vulnerable, the sustained D'Ghor assault and significant Starfleet mobilisation is over.
