General George Custer (1839–1876) rose to the rank of Major General in the United States Army during the Civil War (1861—1865). Custer graduated from West Point two months after the war started and quickly rose in the ranks. For his efforts at the Battle of Aldie (June 17, 1863), he was promoted from First Lieutenant to Brigadier General of Volunteers, making him the youngest officer to attain that rank and one of the youngest Generals in the Union Army.

When Custer graduated from West Point, he received a commission in the U.S. Army in time to take part in the First Battle of Bull Run. After a  short illness, he returned to active duty and served in Major General George McClellan’s Peninsula Campaign. During that campaign, he became the first Union officer to oversee the use of hot-air balloons to spy on Confederate forces. Impressed with Custer’s performance, McClellan appointed him as his aide-de-camp and promoted him to the rank of Captain.

Custer commanded a cavalry division in 1862 and early 1863, taking part in the Battles of Brandy Station and Aldie. On June 29, 1863, the War Department promoted Custer to the rank of Brigadier General of Volunteers, making him the youngest officer to attain that rank and one of the youngest Generals in the Union Army.

In July 1863, Custer had two horses shot from under him while leading charges at the Battle of Gettysburg. During the Civil War, Custer had a total of eleven horses shot from under him. However, he was only wounded one time.

In 1864, Custer served as a cavalry commander with the Army of the Potomac during the Overland Campaign, seeing action at the Battles of the Wilderness, Yellow Tavern, and Trevilian Station. During the fall of 1864, Custer accompanied Major General Philip Sheridan to the Shenandoah Valley and played key roles in the battles of Opequon, Tom’s Brook, and Cedar Creek.

Custer and his cavalry troopers also took part in Sheridan’s scorched earth campaign against Shenandoah Valley residents, locally known as “The Burning.” The widespread destruction of civilian property during the autumn of 1864 incited acts of atrocity between Custer’s soldiers and Confederate General John Mosby’s Rangers. Mosby’s men and Shenandoah Valley residents despised Custer so much that Sheridan warned him “If the Rebs should ever lay you by the heels, they’ll string you up directly.”

Early in 1864, Custer received a brevet promotion to major general in the regular army. He then returned to eastern Virginia and took part in the Petersburg and Appomattox campaigns.
