Fort Abraham Lincoln - Mandan, North Dakota
On May 17, 1876, the troops left Fort Lincoln on the Centennial Campaign, which took the 7th Cavlary into the valley of the Little Big Horn. They were attempting to force non-treaty Indians back to their respective reservations. Outnumbered, outgunned, and out-maneuvered, 260 cavalry troopers would not return to Fort Abraham Lincoln, including every member of the five companies with Custer.
