The battle involved the largest number of casualties of the entire war and is often described as the war’s turning point. Union Maj. Gen. George Gordon Meade’s Army of the Potomac defeated attacks by Confederate Gen. Robert E. Lee’s Army of Northern Virginia, ending Lee’s invasion of the North. Source: Wikipedia.org
