George Armstrong Custer (December 5, 1839 – June 25, 1876) was a United States Army officer and cavalry commander in the American Civil War and the American Indian Wars. Raised in Michigan and Ohio, Custer was admitted to West Point in 1857, where he graduated last in his class in 1861. With the outbreak of the Civil War, Custer was called to serve with the Union Army.

Custer entered West Point as a cadet on July 1, 1857, to become a member of the class of 1862. His class numbered seventy-nine cadets embarking on a five year course of study. With the outbreak of the American Civil War, the course was shortened to four years so that Custer and his class graduated on June 24, 1861. He was 34th in a class of 34 graduates: 23 classmates had dropped out for academic reasons while 22 classmates had resigned to join the Confederacy.

Despite having no direct command experience, Custer became one of the youngest generals in the Union Army at age 23. Custer lost no time in implanting his aggressive character on his brigade, part of the division of Brigadier General Judson Kilpatrick.
