Who was the military leader defeated at the Battle of Little Bighorn?

The military leader defeated at the Battle of Little Bighorn was General Custer. This battle, which occurred on June 25-26, 1876, is famously known as Custer's Last Stand and represents a significant conflict between the U.S. Army and Native American tribes, primarily the Lakota Sioux and Cheyenne. Custer, commanding the 7th Cavalry, underestimated the strength and tactics of the Native American forces, resulting in a decisive defeat for his troops.

Custer's aggressive pursuit of the Native Americans led him to divide his forces, which ultimately contributed to the overwhelming defeat he encountered at the hands of a coalition of tribes led by leaders such as Sitting Bull and Crazy Horse. This battle became a symbol of Native American resistance to U.S. government policies and military actions during that era.

The other leaders mentioned, such as General Grant and General Sheridan, played significant roles in the Civil War and in the broader context of U.S. military history, but neither was involved in the context of the Battle of Little Bighorn. General Tecumseh, on the other hand, was a prominent Shawnee leader whose resistance took place earlier in the early 19th century, long before the events in question.
