Battle of Antietam (or Sharpsburg) stopped General Lee's first invasion of the North. The second invasion was stopped at Gettysburg, PA. In a technical sense, Antietam caused the invading Army of Northern Virginia to retreat from its already launched invasion of the North.
The Union caled it Bull Run.
Antietam
The Battle of Gettysburg
The first Battle of Bull Run (or Battle of Manassas) was the first time the Union Army sent troops across the Potomac River into Confederate territory. The plan was to rout the ill-prepared rebels and force Virginia back into the Union. The Union Army did well at first, but a blunder and a hero got in the way. The blunder occurred when a Union artillery officer was told that rebel soldiers were coming out of a tree line toward their position. The officer assumed they were Union ... the Confederates overran the cannon and captured them. The hero of the day was Stonewall Jackson. As several battalions of Confederates broke and began to run, Jackson rode up and stood his ground in plain view of the enemy. His courage was infectious. The Confederates stopped their retreat and held the ground. A Union force of three times the size of the rebel army was stopped and forced back across the Potomac.
A Union victory was expected at the first Battle of Bull Run. It was indeed a shock to have suffered a defeat.
