7. Battle of Little Bighorn (1876)
On June 25, 1876, during the Great Sioux War, Lieutenant Colonel George Armstrong Custer led the 7th Cavalry Regiment into the Little Bighorn Valley, Montana, aiming to confront a large encampment of Lakota Sioux, Northern Cheyenne, and Arapaho tribes. Custer’s decision to divide his forces into three battalions, including one under his direct command, left them vulnerable and unable to support each other. Intelligence had underestimated the Native American force, which numbered around 2,000 warriors, many armed with superior repeating rifles. The Native American forces, led by leaders such as Crazy Horse and Sitting Bull, mounted a determined defense, resulting in the annihilation of Custer’s battalion. All 210 soldiers under his command were killed, marking the battle as a significant defeat for the U.S. Army and a notable victory for the Native American tribes. The incident has become a cautionary tale in U.S. military history, highlighting the consequences of underestimating the enemy and the importance of strategic coordination.
