The Battle of the Little Bighorn, fought on June 25, 1876, near the Little Bighorn River in Montana Territory, pitted federal troops led by Lieutenant Colonel George Armstrong Custer (1839-76) against a band of Lakota Sioux and Cheyenne warriors. Tensions between the two groups had been rising since the discovery of gold on Native American lands. When a number of tribes missed a federal deadline to move to reservations, the U.S. Army, including Custer and his 7th Cavalry, was dispatched to confront them. Custer was unaware of the number of Indians fighting under the command of Sitting Bull (c.1831-90) at Little Bighorn, and his forces were outnumbered and quickly overwhelmed in what became known as Custer’s Last Stand.

Battle of the Little Bighorn: Mounting Tensions

Sitting Bull and Crazy Horse (c.1840-77), leaders of the Sioux on the Great Plains, strongly resisted the mid-19th-century efforts of the U.S. government to confine their people to Indian reservations. In 1875, after gold was discovered in South Dakota’s Black Hills, the U.S. Army ignored previous treaty agreements and invaded the region. This betrayal led many Sioux and Cheyenne tribesmen to leave their reservations and join Sitting Bull and Crazy Horse in Montana. By the late spring of 1876, more than 10,000 Native Americans had gathered in a camp along the Little Bighorn River–which they called the Greasy Grass–in defiance of a U.S. War Department order to return to their reservations or risk being attacked.

Did you know? Several members of George Armstrong Custer's family were also killed at the Battle of the Little Bighorn, including two of his brothers, his brother-in-law and a nephew.

In mid-June, three columns of U.S. soldiers lined up against the camp and prepared to march. A force of 1,200 Native Americans turned back the first column on June 17. Five days later, General Alfred Terry ordered George Custer’s 7th Cavalry to scout ahead for enemy troops. On the morning of June 25, Custer, a West Point graduate, drew near the camp and decided to press on ahead rather than wait for reinforcements.

Battle of the Little Bighorn: Custer’s Last Stand

At mid-day on June 25, Custer’s 600 men entered the Little Bighorn Valley. Among the Native Americans, word quickly spread of the impending attack. The older Sitting Bull rallied the warriors and saw to the safety of the women and children, while Crazy Horse set off with a large force to meet the attackers head on. Despite Custer’s desperate attempts to regroup his men, they were quickly overwhelmed. Custer and some 200 men in his battalion were attacked by as many as 3,000 Native Americans; within an hour, Custer and all of his soldiers were dead.

The Battle of the Little Bighorn, also called Custer’s Last Stand, marked the most decisive Native American victory and the worst U.S. Army defeat in the long Plains Indian War. The demise of Custer and his men outraged many white Americans and confirmed their image of the Indians as wild and bloodthirsty. Meanwhile, the U.S. government increased its efforts to subdue the tribes. Within five years, almost all of the Sioux and Cheyenne would be confined to reservations.
