Covert intelligence played a critical role in the American Revolution. Connecticut produced an extraordinary number of spies on both sides of the conflict, from the infamous traitor and Norwich-born Benedict Arnold to Patriot Nathan Hale, executed by the British for espionage. Spying during the Revolution entailed coded messages, early submarines with the first exploding torpedoes and the penalty of death for those caught in the act. Despite the risk, some spies even played both sides as double agents, such as Edward Bancroft, who was never caught. With stories of Silas Deane, Ethan Allen, Thomas Knowlton, the Culper Spy Ring and others, author Mark Allen Baker navigates the intrigues, dangers and double crosses of Connecticut's most legendary Revolutionary spies.
