Civil War People: Drawn from Across the Nation
The Civil War was the first conflict that saw the large scale mobilization of the American people. While over 2.2 million served the Union cause, between 1.2 and 1.4 million enlisted in Confederate service. These men were led by officers from a variety of backgrounds ranging from professionally-trained West Pointers to businessmen and political appointees.
While many professional officers did leave the US Army to serve the South, the majority remained loyal to the Union. As the war began, the Confederacy benefited from several gifted leaders, while the North endured a string of poor commanders. In time, these men were replaced by skilled men who would lead the Union to victory.
