This book consists of seven stand-alone accounts of individuals who operated as spies during the American Revolutionary War. They were not trained as covert agents, which meant they had to develop their skills and techniques on their own, often while in the midst of the enemy where discovery meant almost certain death for them, and suffering and hardship for their family and friends. Five of them spied for the American cause and two spied for the British. Not all were motivated by patriotism, and not all escaped capture, yet their often painfully gained experience benefited future operatives and operations. They all were daring, intelligent and resourceful, and each had an unusual personality. Their labors resulted in battlefield victories, thwarted enemy plots, and significantly changed the conduct of the war, yet in spite of their efforts and their riveting stories, they and their deeds have remained relatively unknown.
