Thomas Ryan's masterfully researched and written study builds upon the pioneering work of Edwin C. Fishel, Stephen W. Sears, and others. Spies, Scouts, and Secrets in the Gettysburg Campaign is destined to become a classic Civil War study.

Spies, Scouts, and Secrets in the Gettysburg Campaign is the first book to detail how the intelligence game was played, by both sides, in this momentous campaign, and Thomas Ryan’s experience as an intelligence officer for the Department of Defense brings context to this story it has not had before.
Stephen W. Sears, author of "Gettysburg"
No one has studied the critical role that intelligence played in the Gettysburg Campaign like Tom Ryan. In fact, the role of intelligence is often overlooked, causing scholars and students alike to miss the "why" so important to the "what" that everyone is familiar with. Now, for the first time the vital information collected by the BMI, scouts, spies and civilians - as well as how it was processed and used by the high command and its results, is told here for the first time in detail that helps complete the story of how and why the campaign developed as it did.

Accurate and timely information is the lifeblood of great generalship. Too often do military historians neglect exploring the flow of information and the effect it has on the decision-making of the great captains. In his excellent new book, "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," Author Tom Ryan has given us a new and insightful window into Lee's decisions, and the Union effort to counter them, during the summer of 1863. The legions of Gettysburg students will need to read this book.

In the vast realm of Civil War writing, military intelligence is frequently overlooked or glossed over with little detail. Knowing what the military leaders knew explains why decisions were made. Tom Ryan’s work gives us a clearer picture of what the military leaders knew, how they knew it, and how this impacted their decisions. It fills an often-neglected gap in Civil War literature and answers many questions that might otherwise remain a mystery.
