The Battle of Antietam

The Bloodiest Battle of the Civil War

Commanders and their Armies

General George McClellan, with the help of Union Maj. Gen. Joseph Hooker, led the army of the Potomac (87,000) to confront Robert E. Lee and Thomas "Stonewall" Jackson's army of Northern Virginia (43,000) on September 16, 1862. This happened since General George McClellan wanted to protect the North by stopping Robert E. Lee, who had taken the war to the North for several reasons. Among these were wanting to take the pressure off of the South, winning a battle on Northern soil could get the South help from European powers, and it would also demoralize the North. Soon, on September 17th, McClellan started his vicious assault on Robert E. Lee.

Significance

The significance of this battle is that it remains the single most bloodiest day in American history, with more than 22,720 casualties. This tactical victory for the Union forces allowed Abraham Lincoln to issue his Emancipation Proclamation with complete political cover.

Eyewitness Account

General James Longstreet who fought at the Battle of Antietam wrote, "On the forenoon of the 15th, the blue uniforms of the Federals appeared among the trees that crowned the heights on the eastern bank of the Antietam. The number increased, and larger and larger grew the field of the blue until it seemed to stretch as far as the eye could see, and from the tops of the mountains down to the edges of the stream gathered the great army of McClellan."
