Spies, Scouts, and Secrets in the Gettysburg Campaign: How the Critical Role of Intelligence Impacted the Outcome of Lee's Invasion of the North, June - July 1863 is the first to offer a unique and incisive comparative study of intelligence operations during what many consider the war's decisive campaign.Based upon years of indefatigable research, the author evaluates how Gen. Robert E. Lee used intelligence resources, including cavalry, civilians, newspapers, and spies to gather information about Union activities during his invasion of the North in June and July 1863, and how this intelligence influenced General Lee's decisions.
