Fort Wallace was a US Army fort located in Pennington County, South Dakota, situated along the Cheyenne River and 15 miles southwest of Howes. Built near the former town of Liberty and southwest of Bacchus Station, Fort Wallace was built to maintain law and order in the remote Cumberland Forest region, as well as to keep watch over the local Native American tribes, including the Wapiti. In 1899, the fort was stormed by the outlaws Arthur Morgan and Charles Smith when they launched a rescue mission to free the Wapiti warrior Eagle Flies from the Army amid the Wapiti War, blowing a hole in the wall with dynamite before escaping down the Cheyenne River on canoes.
