Battle of Dead Buffalo Lake - Battle

Battle

Sibley marched to Dead Buffalo lake on July 26 and about noon camped near the shores of the small lake. Mounted Sioux appeared shortly on the hills surrounding the lake and Sibley's camp, threatening an attack. Sibley advanced his artillery, two companies of infantry, and his pioneers to a position about 600 yards in advance of his camp and opened fire at long range on the Indians. The Indians withdrew to a safe distance.

The objective of the Sioux seems to have been to capture the army’s pack train of horses and mules and immobilize Sibley. They first attempted an assault on Sibley's left flank, but were checked by a company of mounted rangers and two companies of infantry. The Indians then disappeared into the hills. Several muleteers in Sibley's camp assumed the engagement was over and took the livestock out of the defense lines to graze. The Sioux re-appeared in force on the right flank and made another effort to capture the stock, but were repulsed in a brief close-quarter fight by two companies of cavalry and 6 companies of infantry. Sitting Bull, armed with only a whip, was said to have counted coup on a muleteer and captured his mule. Failing in their mission to capture most of the horses and mules, the Indians then retired from the field and the battle was over.

One soldier was killed. The soldiers estimated they had killed 15 Sioux. The number of Indian combatants and Indian casualties were often overestimated by the army.
