The Wagon Box Fight was an engagement on August 2, 1867, in the vicinity of Fort Phil Kearny, Wyoming, during Red Cloud's War. A party of 26 US Army soldiers and 6 civilians were attacked by several hundred Lakota Sioux warriors. Although outnumbered, the soldiers were armed with newly supplied breech-loading Springfield Model 1866 rifles and Lever Action Henry rifles, and had a defensive wall of wagon boxes to protect them. They held off the attackers for hours with few casualties, although they lost a large number of horses and mules driven off by the raiders.
