Philadelphia played a key role in the history of spying during the American Revolution because it was the main location for the Continental Congress, was occupied by the British Command, and then returned to Continental control. Philadelphia became a center of spies for the British and Americans--as well as double agents. An important contribution to Revolutionary War history, Spies in the Continental Capital: Espionage Across Pennsylvania During the American Revolution demonstrates that intelligence operations on both sides emanating from Pennsylvania were vast, well-designed, and critical to understanding the course and outcome of the war.

Dr. Benjamin Church, Jr. (1734-1778) was a respected medical man and civic leader in colonial Boston who was accused of being an agent for the British in the 1770s, providing compromising intelligence about the plans of the provincial leadership in Massachusetts as well as important information from the meetings of the First Continental Congress in Philadelphia. In Dr. Benjamin Church, Spy: A Case of Espionage on the Eve of the American Revolution, noted authority John A. Nagy has scoured original documents to establish the best case against Church, identifying previously unacknowledged correspondence and reports as containing references to the doctor and his activities, and noting an incriminating letter in the possession of the Library of Congress that is a coded communication composed by Church to his British contact. Nagy shows that at the cusp of the revolution, when the possibility--let alone the outcome--of an American colonial rebellion was far from assured, Church sought to align himself with the side he thought would emerge victorious--the British crown--and thus line his pockets with money that he desperately needed. A fascinating investigation into a centuries-old intrigue, this well-researched volume is an important contribution to American Revolution scholarship.

From imposters and hidden compartments to secret handshakes and coded letter, here is a thoroughly entertaining account of the role of spycraft during the American Revolution.

NEW YORK TIMES BESTSELLER • Turn: Washington’s Spies, now an original series on AMC Based on remarkable new research, acclaimed historian Alexander Rose brings to life the true story of the spy ring that helped America win the Revolutionary War. For the first time, Rose takes us beyond the battlefront and deep into the shadowy underworld of double agents and triple crosses, covert operations and code breaking, and unmasks the courageous, flawed men who inhabited this wilderness of mirrors—including the spymaster at the heart of it all. In the summer of 1778, with the war poised to turn in his favor, General George Washington desperately needed to know where the British would strike next. To that end, he unleashed his secret weapon: an unlikely ring of spies in New York charged with discovering the enemy’s battle plans and military strategy. Washington’s small band included a young Quaker torn between political principle and family loyalty, a swashbuckling sailor addicted to the perils of espionage, a hard-drinking barkeep, a Yale-educated cavalryman and friend of the doomed Nathan Hale, and a peaceful, sickly farmer who begged Washington to let him retire but who always came through in the end. Personally guiding these imperfect everyday heroes was Washington himself. In an era when officers were gentlemen, and gentlemen didn’ t spy, he possessed an extraordinary talent for deception—and proved an adept spymaster. The men he mentored were dubbed the Culper Ring. The British secret service tried to hunt them down, but they escaped by the closest of shaves thanks to their ciphers, dead drops, and invisible ink. Rose’s thrilling narrative tells the unknown story of the Revolution–the murderous intelligence war, gunrunning and kidnapping, defectors and executioners—that has never appeared in the history books. But Washington’s Spies is also a spirited, touching account of friendship and trust, fear and betrayal, amid the dark and silent world of the spy.

How General Washington Avoided the Peril From Within His Own Forces "It gives me great pain to be obliged to solicit the attention of the honorable Congress to the state of the army...the greater part of the army is in a state not far from mutiny...I know not to whom to impute this failure, but I am of the opinion, if the evil is not immediately remedied and more punctuality observed in future, the army must absolutely break up."--George Washington, September 1775 Mutiny has always been a threat to the integrity of armies, particularly under trying circumstances, and since Concord and Lexington, mutiny had been the Continental Army's constant traveling companion. It was not because the soldiers lacked resolve to overturn British rule or had a lack of faith in their commanders. It was the scarcity of food--during winter months it was not uncommon for soldiers to subsist on a soup of melted snow, a few peas, and a scrap of fat--money, clothing, and proper shelter, that forced soldiers to desert or organize resistance. Mutiny was not a new concept for George Washington. During his service in the French and Indian War he had tried men under his command for the offense and he knew that disaffection and lack of morale in an army was a greater danger than an armed enemy. In Rebellion in the Ranks: Mutinies of the American Revolution, John A. Nagy provides one of the most original and valuable contributions to American Revolutionary War history in recent times. Mining previously ignored British and American primary source documents and reexamining other period writings, Nagy has corrected misconceptions about known events, such as the Pennsylvania Line Mutiny, while identifying for the first time previously unknown mutinies. Covering both the army and the navy, Nagy relates American officers' constant struggle to keep up the morale of their troops, while highlighting British efforts to exploit this potentially fatal flaw.

"Using George Washington's diary as the primary source, Nagy tells the story of [his] experiences during the French and Indian War and his first steps in the field of espionage. Despite what many believe, Washington did not come to the American Revolution completely unskilled in this area of warfare. Espionage was a skill he honed during the French and Indian War and upon which he heavily depended during the Revolutionary War. He used espionage to level the playing field and then exploited it on to final victory"--Amazon.com.
