The Flint and Fire of Fort Union: Firearms of the Fur Trade
NPS: Firearms of all shapes and sizes—everything from large caliber rifles to small pocket pistols—proved essential to Fort Union's daily activities. Guns, a fur trade staple, were supplied to the Northern Plains tribes in exchange for buffalo robes and furs. Having well-armed hunters at remote American Fur Company (AMFCo) posts like Fort Union and their nearby competitors was equally important to residents and visitors; AMFCo's hunters, for instance, procured as many as 800 bison for food each year.
