General Robert E. Lee’s first invasion of the North culminated in the Battle of Antietam, the bloodiest single-day battle in American history. More soldiers were killed or wounded at Antietam than all the American dead in the Revolutionary War, the War of 1812, the Mexican War, and the Spanish-American War combined. On September 17, 1862, General Robert E. Lee and 30,000 Confederate troops faced Major General George McClellan and 60,000 Union troops. It should have been a clear victory for McClellan, especially since his army had captured Lee’s Special Orders No. 191, which directed Stonewall Jackson to march on Harpers Ferry. McClellan failed to use this information wisely, choosing instead to remain cautious. Jackson took Harpers Ferry and moved his 45,000 troops on to Antietam to reinforce Lee’s troops. McClellan was recalled to Washington and was relieved of his command.
