George Armstrong Custer was a United States Army officer and cavalry commander during the American Civil War and the Indian Wars. Born on December 5, 1839, in New Rumley, Ohio, he gained fame for his bold tactics and leadership. Custer played a significant role in several key battles, including the Battle of Gettysburg, where his cavalry helped secure a Union victory. Custer is perhaps best known for his last stand at the Battle of Little Bighorn in 1876, where he and his troops faced a coalition of Native American tribes, including the Lakota and Cheyenne. This battle resulted in a significant defeat for Custer and has become a symbol of the conflicts between the U.S. government and Native Americans.
