500
The costliest battle of the Civil War based on number of casualties. From July 1-3, 1863, the Battle resulted in approximately 51,112 deaths, wounded, missing, or captured.
Despite the fact that the South continued to fight for two more years, it was an important victory for the Union. The Confederacy's retreat from Pennsylvania and the terrible casualties were a turning point in the war. From that point on, the South had to abandon its attempt to invade the North.
