Fort Abraham Lincoln (Mandan, North Dakota, North Dakota)
Mandan, North Dakota · North Dakota · Indian Wars
History & Significance
The U.S. Army was sent to Dakota Territory in June 1872 to protect Northern Pacific Railroad survey crews and workers. Two companies of the 6th Infantry established an infantry post called Fort McKeen on June 14, 1872, which was renamed Fort Abraham Lincoln on November 19, 1872.
Congress authorized the addition of a cavalry post the following year, and the fort relocated approximately one mile south; construction was mostly completed in 1873. In fall 1873, six companies of the 7th Cavalry arrived under Lieutenant Colonel George A. Custer to advance the railroad and support westward expansion.
By 1874, the fort housed nine companies with about 650 men—three companies of the 6th and 17th Infantries and six companies of the 7th Cavalry, making it one of the largest and most important forts on the Northern Plains. Custer led a Black Hills Expedition from the fort in July 1874 to investigate gold mining potential.
The 7th Cavalry departed in May 1876 for the engagement with Dakota tribes; at the Little Bighorn River on June 25, 1876, Dakota, Cheyenne, and Arapaho warriors defeated Custer and 263 of his men. The fort remained the 7th Cavalry headquarters until June 1882, when the regiment transferred to Fort Meade, South Dakota.
The Army evacuated the fort in 1891, by which time it had deteriorated and settlers were dismantling it. In 1907, President Theodore Roosevelt signed the deed to the land over to the state as Fort Abraham Lincoln State Park.
