The Battle of Shiloh
April 7, 1862 — ~3:00 PM
Beauregard, his army exhausted and outnumbered by Grant's reinforced line, orders the Confederate withdrawal to Corinth. Grant's army holds the field — a costly Union victory.
~23,750 casualties over two days — more than every previous American war combined. Shiloh ended any hope of a short, bloodless war.
