How important was intelligence information in the Civil War? We all probably know the famous piece of non-intelligence information, the lateness of Lee learning the Union army had crossed the Potomac River.
But how much did the Army of the Potomac know about the Army of Northern Virginia and where they were in Pennsylvania?
One book I highly recommend? It changed my perspective on the Battle of Gettysburg? The book is, The Secret War for the Union. The Untold Story of Military Intelligence in the Civil War. Edwin C. Fishel. Another is ...The War between the Spies. Alan Axelrod.
The Civil War was a modern war, unlike those of the past. Railroads affected logistics and the size of armies. The telegraph affected intelligence gathering and was a mighty tool of the Union army in Pennsylvania. The Signal department used telescopes and flags to quickly gather fact from line of sight.
Gettysburg was a modern battle, that armies did not fight twenty years earlier.
