Spying in the Civil War. Introduction. Though neither the Union nor the Confederacy had a formal military intelligence network during the Civil War, each side obtained crucial information from spying or espionage operations. From early in the war, the Confederacy set up a spy network in the federal capital of Washington, D.C., home to many southern sympathizers.
The civil war started between April 10-12, 1861. It was started when General Beauregard of the Confederate States of American fired upon Fort Sumter from Charleston, SC. This began one of the most blood fought wars of all times.
