The Civil War had to run its bloody course so that the destiny of the United States could be determined. A bloody course it truly was. Almost 700,000 American soldiers of blue and gray gave their lives in the Civil War to define the nation’s destiny. If civil war erupted today in America and total losses were in the same proportion to population now as they were then, the Northern states would lose 4,000,000 men while the Southern states would suffer 11,000,000 casualties.
