sep 17, 1862 - Battle of Antietam (MD)
September 17th, 1862
Union Gen: McClellan
Confederate Gen: Lee
Union won
Deadliest one-day battle. Confederates were weary and outnumbered.
Thousands of deaths in hours as Confederates defended against assaults
on battlefield and Bloody Lane. Lee retreated to VA next day and
McClellan didn't pursue and was removed. Ended Lee's attempt to invade
the North. Led to release of Emancipation Proclamation.
