1876 - June 25 – American Indian Wars – Battle of the Little Bighorn:

300 men of the U.S. 7th Cavalry Regiment under Lieutenant Colonel George Armstrong Custer are wiped out by 5,000 Lakota, Cheyenne and Arapaho led by Sitting Bull and Crazy Horse.



The Battle of the Little Bighorn, fought on June 25, 1876, was a significant clash during the American Indian Wars between the United States Army and various Native American tribes, primarily the Lakota Sioux, Cheyenne, and Arapaho. Located near the Little Bighorn River in Montana Territory, the battle was sparked by tensions over Native American resistance to forced relocation and encroachment on their lands. Led by Lieutenant Colonel George Armstrong Custer, the 7th Cavalry Regiment aimed to engage and subdue the Native American forces, but severely underestimated their numbers and tactical prowess.

In a surprising turn, Custer and his men encountered overwhelming resistance from a combined force of Native warriors, led by leaders like Sitting Bull and Crazy Horse. The battle resulted in a devastating defeat for the US Army, with Custer and his entire detachment of over 200 soldiers killed.
