Custer, Wisconsin Custer, Wisconsin Custer is an unincorporated community located in the town of Stockton, in Portage County, Wisconsin, United States. The origin of the communities name is not confirmed but general consensus is it was named after Lt. Col. George Armstrong Custer, who was defeated during the battle of the Little Big Horn in 1876. The Custer post office was established in December, 1876 just six months after the battle of Little Big Horn. The community was originally called "Dawson". The only evidence to where this name came from was an August 8, 1854 land deed marking the sale of a
Battle of the Little Bighorn known today as Custer Hill. At least 28 bodies (the most common number associated with burial witness testimony), including that of scout Mitch Bouyer, were discovered in or near that gulch, their deaths possibly the battle's final actions. Although the marker for Mitch Bouyer has been accounted for as being accurate through archaeological and forensic testing, it is some 65 yards away from Deep Ravine. Other archaeological explorations done in Deep Ravine have found no human remains associated with the battle. According to Indian accounts, about 40 men made a desperate stand around Custer on Custer Hill, delivering volley fire.
