The Confederacy, emboldened by Second Bull Run,…
1862 CE
General Lee leads forty-five thousand men of the Army of Northern Virginia across the Potomac River into Maryland on September 5.
Lincoln now restores Pope's troops to McClellan.
McClellan and Lee fight at the Battle of Antietam near Sharpsburg, Maryland, on September 17, 1862, the bloodiest single day in United States military history.
Lee's army, checked at last, returns to Virginia before McClellan can destroy it.
Antietam is considered a Union victory because it has halted Lee's invasion of the North and has provided an opportunity for Lincoln to announce his Emancipation Proclamation.
