ダコタ準州
Dakota Territory was not directly involved in the American Civil War but did raise some troops to defend the settlements following the Dakota War of 1862 which triggered hostilities with the Sioux tribes of Dakota Territory. The Department of the Northwest sent expeditions into Dakota Territory in 1863, 1864 and 1865. It also established forts in Dakota Territory to protect the frontier settlements of the Territory, Iowa and Minnesota and the traffic along the Missouri River.
