Custer fought in the Civil War at the first battle of Bull Run, distinguished himself as a member of General McClellan's staff in the Peninsular campaign, and was made a brigadier general of volunteers in June, 1863. The youngest general in the Union army, Custer ably led a cavalry brigade in the Gettysburg campaign. He fought in Virginia in the great cavalry battle at Yellow Tavern and in General Sheridan's Shenandoah Valley campaign. Made a divisional commander in Oct., 1864, he defeated (Oct. 9) Gen. Thomas L. Rosser at Woodstock. After dispersing the remnants of Gen. Jubal A. Early's command at Waynesboro on Mar. 2, 1865, he was in the advance in pursuit of Lee's army beyond Richmond. Custer received the Confederate flag of truce, was present at the surrender at Appomattox Courthouse, and was promoted major general of volunteers. His record (he had also been brevetted a major general in the regular army), considering his youth, was one of the most spectacular of the war.
