Invisible Ink: Spycraft of the American Revolution


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 Revolutionary War to exchange secret information.

During the American Revolution, espionage was critical to the successes and failures of both Continental and British efforts, and those employed in cloak-and-dagger operations always risked death. 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.
