The Battle of New Market was fought on May 15, 1864, in Virginia during the Valley Campaigns of 1864 in the American Civil War. A makeshift Confederate army of 4,100 men defeated the larger Army of the Shenandoah under Major General Franz Sigel, delaying the capture of Staunton by several weeks.

The battle is primarily remembered today for being the only time in American history a school's student body was used as an organized combat unit. During the battle Confederate general John C. Breckinridge ordered cadets from the Virginia Military Institute (VMI), some of them child soldiers no older than 15, to join an attack on the Union lines. The event has gone on to become central to many of the Institute's myths and traditions.
