Title: John André
Content:  John André (2 May 1750/1751 – 2 October 1780) was a major in the British Army and head of its Secret Service in America during the American Revolutionary War. He was hanged as a spy by the Continental Army for assisting Benedict Arnold's attempted surrender of the fort at West Point, New York, to the British. André is typically remembered favorably by historians as a man of honor, and several prominent American leaders of the time including Alexander Hamilton and Marquis de Lafayette did not agree with his fate.

Content:  "Anderson" admitted to his true identity (that he was André) and was tried, convicted, and executed as a spy. Arnold, learning that André had been taken and that his own treachery was no doubt was exposed, fled West Point before he could be captured, and joined the British forces. General Washington demanded effective counterintelligence work from his subordinates. On March 24, 1776, for example, he wrote: "There is one evil I dread, and that is, their spies. I could wish, therefore, the most attentive watch be kept... I wish a dozen or more of honest, sensible and diligent men, were employed... in order to question, 
Title: Intelligence in the American Revolutionary War
Content:  On June 5, 1776, the Congress appointed John Adams, Thomas Jefferson, Edward Rutledge, James Wilson, and Robert Livingston "to consider what is proper to be done with persons giving intelligence to the enemy or supplying them with provisions." They were charged with revising the Articles of War in regard to espionage directed against the American forces. The problem was an urgent one: Dr. Benjamin Church, chief physician of the Continental Army, had already been seized and imprisoned as a British agent, but there was no civilian espionage act, and George Washington thought the existing military law did not provide punishment severe enough to afford a deterrent. On November 7, 1775, the death penalty was added for espionage to the Articles of War, but the clause was not applied retroactively, and Dr. Church escaped execution. On August 21, 1776, the committee's report was considered by the Congress, which enacted the first espionage act. It was resolved further that the act "be printed at the end of the rules and articles of war." On February 27, 1778, the law was broadened to include any "inhabitants of these states" whose intelligence activities aided the enemy in capturing or killing revolutionary forces.
Title: History of espionage
Content:  During the American Revolution, 1775–1783, American General George Washington developed a successful espionage system to detect British locations and plans. In 1778, he ordered Major Benjamin Tallmadge to form the Culper Ring to collect information about the British in New York. Washington was usually mindful of treachery, but he ignored incidents of disloyalty by Benedict Arnold, his most trusted general. Arnold tried to betray West Point to the British Army, but was discovered and barely managed to escape. The British intelligence system was weak; it completely missed the movement of the entire American and French armies from the Northeast to Yorktown, Virginia, where they captured the British invasion army in 1781 and won independence. Washington has been called "Americas First Spymaster".

Title: Intelligence in the American Revolutionary War
Content:  that the British planned to attack a French expedition that had just landed in Newport, Rhode Island, Washington planted information with known British agents indicating that he intended to move against New York City. The British commander held back the troops headed for Rhode Island. With elaborate deception, Washington masked his movement toward Chesapeake Bay and Yorktown by convincing the British that he was moving on New York. At Yorktown, James Armistead, a slave who had joined Lafayette's service with his master's permission, crossed into Cornwallis' lines in the guise of an escaped slave, and was recruited by Cornwallis to return to American lines as a spy. Lafayette gave him a fabricated order that was destined for a large number of nonexistent replacements. Armistead delivered the 
Title: Cato (spy)
Content:  Cato was an enslaved African American Black Patriot spy and courier during the American Revolution. Cato's enslaver, Hercules Mulligan, gathered intelligence through his personal connections as well as clients at his New York City tailoring shop, and Cato carried the information on horseback to Continental Army officers and other revolutionaries, including Alexander Hamilton and George Washington, and often through British-held territory. Cato's messages are credited with likely saving Washington's life on two occasions. Other than his intelligence activities with Mulligan, no definite information about Cato is available, including his activities following the war.
Title: Culper Ring
Content:  The Culper Ring was a network of spies active during the American Revolutionary War, organized by Major Benjamin Tallmadge and General George Washington in 1778 during the British occupation of New York City. The name "Culper" was suggested by George Washington and taken from Culpeper County, Virginia. The leaders of the spy ring were Abraham Woodhull and Robert Townsend, using the aliases of "Samuel Culper Sr." and "Samuel Culper Jr.", respectively; Tallmadge was referred to as "John Bolton." While Tallmadge was the spies' direct contact, Washington often directed their operations. The ring was tasked to provide Washington information on British Army operations in New York City, the British headquarters. Its members operated mostly in New York City, Long Island, and Connecticut between late October 1778 and the British evacuation of New York in 1783. The information 
Title: James Rivington
Content:  Rivington, who opened a drug shop, would have been the last New Yorker suspected of playing the part of a spy for the Continentals, but he furnished General George Washington with important information. Rivington's silent partner in the coffeehouse was Robert Townsend, alias "Samuel Culper, Jr.," one of the principal agents of the American Culper Spy Ring. Rivington was recruited by Townsend in late summer 1779 and was given the code name "726." Rivington's communications were written on the book cover boards so that no one would see them, bound in the covers of books, and he conveyed to the American camp by agents who were ignorant of their service.
