Fort Koshkonong

Fort Koshkonong (Fort Cosconong) was located at a site which today is in the city of Fort Atkinson, Wisconsin, about three blocks east of Main St. along Milwaukee Ave. General Henry Atkinson was the commander of the fort during the Black Hawk War. Intended to control the confluence of the Bark and Rock rivers, it was used as a station for local militia units and the US regulars in the region to scout the British Band. 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. Local settlers dismantled it for the wood as the town continued to develop. Today the fort's original location along the Rock River is marked with a monument.

The city built a replica of the fort during the Great Depression of the 1930s as a Works Progress Administration (WPA) project funded by the President Franklin D. Roosevelt administration. Its overall size is somewhat larger than the original fort, but gives a good representation of how it looked during the Black Hawk War.

Fort Koshkonong shares its name with Lake Koshkonong, which is several miles downriver. Very shallow, the lake at the time of the fort's activity was more of a marsh with the river flowing through it. It increased in size when the river was dammed and is one of the larger lakes in Wisconsin in acreage.
