Battle of the Little Bighorn Battle of the Little Bighorn The Battle of the Little Bighorn, known to the Lakota and other Plains Indians as the Battle of the Greasy Grass and also commonly referred to as Custer's Last Stand, was an armed engagement between combined forces of the Lakota, Northern Cheyenne, and Arapaho tribes and the 7th Cavalry Regiment of the United States Army. The battle, which resulted in the defeat of US forces, was the most significant action of the Great Sioux War of 1876. It took place on June 25–26, 1876, along the Little Bighorn River in the Crow Indian Reservation in
George Armstrong Custer and form a skirmish line. They were soon overcome by mounted Lakota and Cheyenne warriors who counterattacked "en masse" against Reno's exposed left flank, forcing Reno and his men to take cover in the trees along the river. Eventually, however, this position became untenable, and the troopers were forced into a bloody retreat up onto the bluffs above the river, where they made their own stand. This, the opening action of the battle, cost Reno a quarter of his command. Custer may have seen Reno stop and form a skirmish line as Custer led his command to the northern end
