Fort Dilts

Fort Dilts was a makeshift sod fort built near Rhame, North Dakota, United States, in September 1864 to fend off attacks by Hunkpapa Sioux Indians led by Sitting Bull upon an encircled wagon train of would-be gold-miners and a small military escort of convalescent soldiers.

The wagon train had set out from Fort Ridgely, Minnesota, under the command of Captain James L. Fisk of the U.S. Quartermaster Corps. In 1864, amidst the American Civil War, the Dakota Territory was relatively short of military protection. On September 2, the party came under attack by Sitting Bull and a group of Hunkpapa Sioux. Two days later, still harassed by the Sioux, the expedition found a suitable spot and constructed a defensive perimeter out of sod stacked 6.5 ft high and 300 ft in diameter. The defenders named it Fort Dilts in honor of Jefferson Dilts, one of eight U.S. Army soldiers who had been killed, out of 50. A number of civilians died also. Lieutenant Smith and fifteen others managed to reach Fort Rice, and reinforcements arrived to rescue the defenders on September 20.

Fort Dilts State Historic Site has been a North Dakota historic site since 1932. As "Fort Dilts", it was listed on the National Register of Historic Places in 1980. The listing was for 8.3 acre with one contributing site and one contributing structure. Remaining at the site are a sod enclosure, wagon ruts, several grave markers, and an interpretive sign.
