“John Nagy has devoted his astonishing research skills to unearthing the truth about the least known and most dangerous spy in American history.”—Thomas Fleming, author of Liberty! The American Revolution

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. Despite his eminence as a surgeon—he conducted an autopsy on one of the victims of the Boston Massacre—and his own correspondence and the numbers of references to him from contemporaries, no known image of him exists and many aspects of his life remain obscure. What we do know is that George Washington accused him of being a traitor to the colonial cause and had him arrested and tried; after first being jailed in Connecticut and then Massachusetts, during which he continued to profess his innocence, he was allowed to leave America on a British vessel in 1778, but it foundered in the Atlantic with all hands lost. The question of whether Dr. Benjamin Church was working for the British has never been conclusively demonstrated, and remains among the mysteries of the American Revolution.

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.

The Critical Role of Espionage During the War of Independence and the Techniques Spies Used
During the American Revolution, espionage was critical to the successes and failures of both Continental and British efforts, and those employed in cloakand- dagger operations always risked death. While the most notorious episode of spying during the war—the Benedict Arnold affair—was a failure, most intelligence operations succeeded. Spycraft was no more wholly embraced than by the American commander-in-chief, George Washington. Washington relied on a vast spy network and personally designed sophisticated battle plan deceptions and counterintelligence efforts, some surprisingly modern in form. In Invisible Ink: Spycraft of the American Revolution, award-winning author John A. Nagy briefly traces the history of spy techniques from ancient China through Elizabethan England before embarking on the various techniques used by spies on both sides of the war to exchange secret information. These methods included dictionary codes, diplomatic ciphers, dead drops, hidden compartments (such as a hollowed-out bullet or a woman’s garter), and even musical notation, as well as efforts of counterintelligence, including “Black Chambers,” where postal correspondence was read by cryptologists. Throughout, the author provides examples of the various codes and ciphers employed, many of which have not been previously described. In addition, the author analyzes some of the key spy rings operating during the war, most notably the Culper ring that provided information to Washington from inside British-controlled New York City. Based on nearly two decades of primary research, including the author’s discovery of previously unrecognized spies and methods, Invisible Ink is a major contribution to the history of conflict and technology.

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.

The Critical Role of British, French, and American Intelligence Operations in Colonial Pennsylvania
It did not take long after the Seven Years’ War—the French and Indian War in North America—for France to return spies to America in order to determine the likelihood of regaining the territory they lost to Britain. One of the key places of French espionage was the colony of Pennsylvania since its frontier had been an important crossroads of French influence in North America. The French recognized then that there was a real possibility that the colonies would seek their independence from Britain. Against this backdrop, award-winning historian John A. Nagy begins his investigation of espionage in colonial Pennsylvania.

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. George Washington was a firm believer in reliable military intelligence; after evacuating New York City, he neglected to have a spy network in place: when the British took over Philadelphia, he did not make the same mistake, and Washington was able to keep abreast of British troop strengths and intentions. Likewise, the British used the large Loyalist community around Philadelphia to assess the abilities of their Continental foes, as well as the resolve of Congress. In addition to describing techniques used by spies and specific events, such as the Major André episode, Nagy has scoured rare primary source documents to provide new and compelling information about some of the most notable agents of the war, such as Lydia Darragh, a celebrated American spy.

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.
