The famous battle that took place on June 25, 1876, was the Battle of Little Bighorn, where U.S. Army forces, led by Lt. Colonel George Custer, faced off against a coalition of Native American tribes, including the Lakota Sioux and Cheyenne. The battle is notable for Custer’s defeat, as his troops were overwhelmed by the much larger Native American forces. The event is emblematic of the broader conflicts and injustices faced by Indigenous peoples in the U.S. during westward expansion and has become a symbol of resistance against U.S. military aggression.
