The Battle of the Little Bighorn — also known as Custer's Last Stand and Custer Massacre and, in the parlance of the relevant Native Americans, the Battle of the Greasy Grass — was an armed engagement between a Lakota-Northern Cheyenne combined force and the 7th Cavalry of the United States Army. It occurred June 25–June 26, 1876, near the Little Bighorn River in the eastern Montana Territory.
The battle was the most famous incident in the Indian Wars and was a victory for the Lakota and Northern Cheyenne. A U.S. cavalry detachment commanded by Lieutenant Colonel George Armstrong Custer was annihilated.
