Quick BriefThe U.S. Army established Fort Atkinson on May 31, 1840, to provide neutral territory for the Winnebago (Ho-Chunk) as they were resettled from Wisconsin into northeast Iowa. Completed in 1842, the fort included 24 buildings and an 11-foot, 9-inch stockade wall. It was the only fort ever built to protect Native Americans, sheltering the Winnebago from the Sioux to the north and the Sac and Fox to the south.

History & Significance

The fort was meant to provide neutral territory for interactions with the Winnebago People as they were resettled from Wisconsin into northeast Iowa. The 1830 Treaty of Prairie du Chien established the Neutral Ground as a 40-mile-wide strip between the Mississippi and Des Moines Rivers; originally intended as a buffer zone between the Sac and Fox and Sioux nations, the land was designated for the Ho-Chunk (Winnebago) tribe after their removal from Wisconsin.

Captain Isaac Lynde led a detachment of the 5th Infantry's Company F, totaling 82 officers and men from Fort Crawford, establishing camp on May 31, 1840; the camp was named for Brigadier General Henry Atkinson, the Department Commander prominent in military operations in the upper Mississippi valley. Although no combat occurred at the fort, General Atkinson selected a high bluff site for defensive strength; three of six years of regular troop garrison were spent constructing the post, with major buildings and stockade built between 1842 and 1845.

On June 20, 1846, regular army troops were reassigned to the Mexican-American War; Iowa volunteers then staffed the fort until its abandonment following the Winnebago's removal. In 1921 the State of Iowa took ownership and established it as part of the state park system. In February 2013 the fort was listed on the National Register of Historic Places as Fort Atkinson Historic District.
