How many American soldiers died in the American Civil War?

Answer 1

For more than a century it was accepted that about 620k Americans died in the conflict, with more than half of those dying off the battlefield from disease or infected wounds. Later estimations have concluded it could be about 750k.

Answer 2

In the entire Civil War, about 650,000 American soldiers and sailors died. Many southern military units did not keep records, so the numbers will always be approximate.
