Fort Koshkonong (Fort Cosconong) was a military fort located near the present-day city of Fort Atkinson, Wisconsin. Intended to control the confluence of the Bark and Rock rivers, it was used as a station for local militia units and the U.S. regulars in the region to scout the British Band, a group of Native Americans who fought against government units during the 1832 Black Hawk War. General Henry Atkinson was the commander of the fort during the war. Black Hawk was in the same general area, but evaded capture and started to flee towards the Wisconsin River. The original fort was abandoned by the Army following the conflict.
