The first of this battle was with Pope against Lee. On September 17, 1862, at the little town of Sharpsburg on a creek, this battle began. Lee had 50,000 men; McClellan had 100,000. In the bloodiest single day of the war, over 13,000 Confederates died or were wounded; the Union lost over 12,000 soldiers. This battle too was basically a draw. Lee’s invasion of the North was stopped, and he retreated into Virginia. The North claimed victory.
