Many uniforms, weapons and other items belonging to the US Army were on display in Fort Lincoln State Park. It was an active base built in 1872; in 1873, the 7th Cavalry were stationed here commanded by General George Armstrong Custer.

Yes, THAT General Custer. He departed the fort in 1876 with soldiers to fight in the Great Sioux War of 1876-1877. As we all know, he never returned as he was killed at the Battle of the Little Bighorn.
