How many people were killed in the Civil War?

Nearly 3,000 people died in the terrorist attacks of September 11, 2001. About the same number of men died in the first 15 minutes at Grant’s assault at Cold Harbor on June 3, 1864. But the Civil War was the bloodiest ever fought on American soil: 618,000 people died — more than WWI, WWII, the Korean War, and the Vietnam War combined.
