In the drawing rooms of Washington and the prisons of Richmond, a different kind of war was being fought - invisible, brutal, and decided not by cannon fire but by secrets kept and secrets stolen.

Rose O'Neal Greenhow ran a Confederate spy ring from blocks away from the White House, providing the intelligence that helped win the First Battle of Bull Run. Elizabeth Van Lew built the most sophisticated Union intelligence network inside the Confederate capital, her reports flowing directly to Ulysses Grant's headquarters. Harriet Tubman led a network of Black scouts through Confederate South Carolina, gathering intelligence that freed more than 700 enslaved people in a single night.

Drawing on military records, firsthand memoirs, and decades of Civil War scholarship, Traitors, Spies, and Secret Agents brings together twenty gripping true stories from the most secretive theater of America's bloodiest conflict.

History recorded the battles. It forgot most of them. This book remembers.
