The first U.S. Army post built in northern Dakota Territory was Fort Abercrombie on the Red River. (See Map 1) The fort was built in 1858 at the crossroads of the Red River and the oxcart trails heading north to Fort Garry in Canada. Wagon trails led through that point to the gold fields in Canada, Montana, and Idaho. In 1860, the post was re-built on high ground on the west bank of the Red River.
When war began between the Santee Dakotas of southern Minnesota and the U.S. government (1862), the soldiers at Fort Abercrombie quickly began to build fortifications out of the large barrels used to store pork, beef, and flour. Dirt was packed around the barrels. Cannons were placed on three corners.
Several times in the next several weeks, Dakotas attacked the post, but were repelled by the soldiers. On September 23, reinforcements arrived and the Dakotas left the area. Fort Abercrombie remained an active Army post until 1877. The railroad and the establishment of reservations for the Dakotas had taken over the role of the post.
A series of important Army posts were established along the Missouri River following the U.S.-Dakota War. General Alfred Sully located these posts during his trips up the Missouri River in 1864 and 1865. The first was Fort Rice, just north of the mouth of the Cannonball River. Fort Rice was occupied from 1864 to 1878. Fort Berthold was built on the site of a fur-trading post. Two years later, the military function of Fort Berthold was abandoned and the military operations moved to the new Fort Stevenson a few miles away. (See Image 1)
Fort Buford was built at about the same time as Fort Stevenson. (See Image 2) Both were built under the leadership of General Regis de Trobriand. General de Trobriand was born in France, but had come to the United States for the purpose of becoming an Army officer. (See Image 3)
In 1872, Fort Abraham Lincoln, a cavalry post, was built on the Missouri River near the mouth of the Heart River. (See Image 4) George Armstrong Custer commanded the post the first three years. (See Image 5) Fort Abraham Lincoln was associated with Fort McKean, a nearby infantry post.
These Army posts along the Missouri River had two purposes. The first purpose was to contain and control the Teton Dakotas. The eastern boundary of the treaty lands of the Dakota tribes was the Missouri River. The second purpose was to protect railroad workers and settlers who were very slowly moving into the region.
Several other Army posts were located in northern Dakota Territory. Many of these had a very short existence. Before the Northern Pacific railroad was built, the soldiers at these forts helped to move the U.S. mail across the territory. The posts also served as stopping places for freight wagons and travelers. This chart offers more details on the other Army posts.

Why is this important? Military occupation of Dakota Territory brought about a major shift in the population of the northern Great Plains. The region had been homeland and hunting land for the Arikaras, Mandans, Hidatsas, Chippewas, Western Dakotas, Eastern Dakotas, and Middle Dakotas for centuries. (See Image 6) In addition, other tribes such as the Crows and Assiniboines traveled into the area to hunt and trade. With the exception of fur traders and soldiers, non-Indians did not take an interest in the area until the railroad was built. The railroad could not be built until the Army had established a strong presence in the area.
