George Washington, Spymaster
Without his brilliance at espionage the Revolution could not have been won
February/March 2000 | Volume 51, Issue 1
George Washington a master of espionage? It is commonly understood that without the Commander in Chief’s quick mind and cool judgment the American Revolution would have almost certainly expired in 1776. It is less well known that his brilliance extended to overseeing, directly and indirectly, extensive and very sophisticated intelligence activities against the British.
In his 1975 study of Washington’s generalship, Honeyman told Rall about his narrow “escape” and assured him the Americans were half-naked and freezing.
The Way of the Fox, Lt. Col. Dave Richard Palmer has called this reversal “a masterpiece of strategic thought, a brilliant blueprint permitting a weak force to combat a powerful opponent.” It soon became apparent that for the blueprint to be followed, Washington would have to know what the British were planning to do, and he would have to be able to prevent them from finding out what he was doing. In short, espionage was built into the system.
Washington had wanted to be a soldier almost from the cradle and seems to have acquired the ability to think in military terms virtually by instinct. In the chaos of mid-1776, with half his army deserting and the other half in a funk and all his generals rattled, he kept his head and reversed his strategy. The Americans had started with the idea that a general action, as an all-out battle was called, could end the conflict overnight, trusting that their superior numbers would overwhelm the presumably small army the British could afford to send to our shores. But the British sent a very big, well-trained army, which routed the Americans in the first several battles in New York. Washington sat down in his tent on Harlem Heights and informed the Continental Congress that he was going to fight an entirely different war. From now on, he wrote, he would “avoid a general action.” Instead he would “protract the war.”
In his 1975 study of Washington’s generalship,
He was involved in figuring out how to burn down New York City despite orders not to.
Washington had been acquainted with British colonial officials and generals and colonels since his early youth, and he knew how intricately espionage was woven into the entire British military and political enterprise. Any Englishman’s mail could be opened and read if a secretary of state requested it. Throughout Europe every British embassy had its intelligence network.
Thus Washington was not entirely surprised to discover, shortly after he took command of the American army in 1775, that his surgeon general, Dr. Benjamin Church, was telling the British everything that went on in the American camp at Cambridge, Massachusetts. He was surprised to find out, not long after he had transferred his operations to New York in the spring of 1776, that one of his Life Guard, a soldier named Thomas Hickey, was rumored to be involved in a plot to kill him.
By that time Washington had pulled off his own opening gambit in a form of intelligence at which he soon displayed something close to genius: disinformation. Shortly after he took command in Cambridge, he asked someone how much powder the embryo American army had in reserve. Everyone thought it had three hundred barrels, but a check of the Cambridge magazine revealed most of that had been fired away at Bunker Hill. There were only thirty-six barrels—fewer than nine rounds per man. For half an hour, according to one witness, Washington was too stunned to speak. But he recovered and sent people into British-held Boston to spread the story that he had eighteen hundred barrels, and he spread the same rumor throughout the American camp.
In chaotic New York, grappling with a large and aggressive British army, deserting militia, and an inapplicable strategy, Washington temporarily lost control of the intelligence situation. That explains the dolorous failure of Capt. Nathan Hale’s mission in September 1776. Hale, sent to gather information behind British lines, was doomed almost from the moment he volunteered. He had little or no contact with the American high command, no training as a spy, no disguise worthy of the name, and an amorphous mission: to find out whatever he could wherever he went.
There is little evidence that Washington was even aware of Hale’s existence. He was involved in something far more serious: figuring out how to burn down New York City in order to deprive the British of their winter quarters, despite orders from the Continental Congress strictly forbidding him to harm the place. He looked the other way while members of Hale’s regiment slipped into the city; they were experts at starting conflagrations thanks to a tour of duty on fire ships—vessels carrying explosives to burn enemy craft—on the Hudson.
On September 21 a third of New York went up in flames. The timing was disastrous for Hale, who was captured the very same day. Anyone with a Connecticut accent became highly suspect, and the British caught several incendiaries and hanged them on the spot. They gave Hale the same treatment: no trial, just a swift, humiliating death. Hale’s friends were so mortified by his fate, which they considered shameful, that no one mentioned his now-famous farewell speech for another fifty years. Then an old man told his daughter about it, and Yale College, seeking Revolutionary War heroes among its graduates, quickly immortalized him.
Washington never said a word about Hale. His only intelligence comment at the time concerned New York. The fire had destroyed Trinity Church and about six hundred houses, causing no little discomfort for the British and the thousands of Loyalist refugees who had crowded into the city. In a letter, Washington remarked that “Providence, or some good honest fellow, has done more for us than we were disposed to do for ourselves.”
One of Hale’s best friends, Maj. Benjamin Tallmadge, never got over his death. He probably talked about it to Washington, who assured him that once they got the protracted war under control, all espionage would be handled from Army headquarters, and no spy’s life would be wasted the way Hale’s had been.
Surviving long enough to fight an extended conflict was no small matter. In the weeks after Hale’s death, disaster after disaster befell the American army. Washington was forced to abandon first New York and then New Jersey. On the other side of the Delaware, with only the shadow of an army left to him, he issued orders in December 1776 to all his generals to find “some person who can be engaged to cross the river as a spy” and added that “expense must not be spared” in securing a volunteer.
He also rushed a letter to Robert Morris, the financier of the Revolution, asking for hard money to “pay a certain set of people who are of particular use to us.” He meant spies, and he had no illusion that any spy would risk hanging for the paper money the Continental Congress was printing. Morris sent from Philadelphia two canvas bags filled with what hard cash he could scrape together on an hour’s notice: 410 Spanish dollars, 2 English crowns, 10 shillings, and 2 sixpence.
The search soon turned up a former British soldier named John Honeyman, who was living in nearby Griggstown, New Jersey. On Washington’s orders Honeyman rediscovered his loyalty to the king and began selling cattle to several British garrisons along the Delaware. He had no trouble gaining the confidence of Col. Johann Rail, who was in command of three German regiments in Trenton. Honeyman listened admiringly as Rail described his heroic role in the fighting around New York and agreed with him that the Americans were hopeless soldiers.
On December 22, 1776, having spent about a week in Trenton, Honeyman wandered into the countryside, supposedly in search of cattle, and got himself captured by an American patrol and hustled to Washington’s headquarters. There he was publicly denounced by the Commander in Chief as a “notorious” turncoat. Washington insisted on interrogating him personally and said he would give the traitor a chance to save his skin if he recanted his loyalty to the Crown.
A half-hour later the general ordered his aides to throw Honeyman into the guardhouse. Tomorrow morning, he stated, the Tory would be hanged. That night Honeyman escaped from the guardhouse with a key supplied by Washington and dashed past American sentries, who fired on him. Sometime on December 24 he turned up in Trenton and told Colonel Rall the story of his narrow escape.
Washington had Tallmadge equip all his spies with cipher codes, invisible ink, and aliases.
The German naturally wanted to know what Honeyman had seen in Washington’s camp, and the spy assured him that the Americans were falling apart. They were half-naked and freezing, and they lacked the food and basic equipment, such as shoes, to make a winter march. Colonel Rail, delighted, prepared to celebrate Christmas with no military worries to interrupt the feasting and drinking that were traditional in his country. He never dreamed that Honeyman had given Washington a professional soldier’s detailed description of the routine of the Trenton garrison, the location of the picket guards, and everything else an assaulting force would need to know.
At dawn on December 26 Washington’s ragged Continentals charged through swirling snow and sleet to kill the be-sotted Colonel Rail and capture most of his troops. New Jersey had been on the brink of surrender; now local patriots began shooting up British patrols, and the rest of the country, in the words of a Briton in Virginia, “went liberty mad again.”
Washington set up a winter camp in Morristown and went to work organizing American intelligence. He made Tallmadge his second-in-command, though he was ostensibly still a major in the 2d Continental Dragoons. That regiment was stationed in outposts all around the perimeter of British-held New York, and Tallmadge visited these units regularly, supposedly to make sure that all was in order but actually working as a patient spider setting up spy networks inside the British lines. His methods, thanks to Washington’s tutelage, could not have been more sophisticated. He equipped his spies with cipher codes, invisible ink, and aliases that concealed their real identities. The invisible ink, which the Americans called “the stain,” had been invented by Dr. James Jay, a brother of the prominent patriot John Jay, living in England. It was always in short supply.
Two of the most important American agents operating inside British-held New York were Robert Townsend, a Quaker merchant, and Abraham Woodhull, a Setauket, Long Island, farmer. Their code names were Culper Jr. and CuIper Sr. As a cover, Townsend wrote violently Loyalist articles for the New York Royal Gazette; this enabled him to pick up information from British officers and their mistresses, and he sent it on to Woodhull via a courier named Austin Roe.
Woodhull would then have a coded signal hung on a Setauket clothesline that was visible through a spyglass to Americans on the Connecticut shore. A crew of oarsmen would row across Long Island Sound by night, collect Townsend’s letters, and carry them to Tallmadge’s dragoons, who would hurry them to Washington. The general applied a “sympathetic fluid” to reveal the secret messages written in Dr. Jay’s “stain.”
When the British occupied Philadelphia, in 1777, Washington salted the city with spies. His chief assistant there was Maj. John Clark, a cavalryman who became expert at passing false information about American strength at Valley Forge to a spy for the British commander General Howe. Washington laboriously wrote out muster reports of the Continental Army, making it four or five times its actual size; the British, recognizing the handwriting, accepted the information as fact and gave the spy who had obtained it a bonus. Washington must have enjoyed this disinformation game; at one point, describing a particularly successful deception, Clark wrote, “This will give you a laugh.”
The most effective American spy in Philadelphia was Lydia Darragh, an Irish-born Quaker midwife and undertaker. The British requisitioned a room in her house to serve as a “council chamber” and discussed their war plans there. By lying with her ear to a crack in the floor in the room above, Mrs. Darragh could hear much of what they said. Her husband wrote the information in minute shorthand on scraps of paper that she hid in large cloth-covered buttons. Wearing these, her fourteen-year-old son would walk into the countryside to meet his brother, a lieutenant in the American army. He snipped off the buttons, and the intelligence was soon in Washington’s hands.
Mrs. Darragh’s biggest coup was getting word to Washington that the British were about to make a surprise attack on his ragged army as it marched to Valley Forge in early December 1777. When the attack came, the Continentals were waiting with loaded muskets and cannon, and the king’s forces withdrew.
The British returned to Philadelphia determined to find whoever had leaked their plan. Staff officers went to Mrs. Darragh’s house and demanded to know exactly when everyone had gone to bed the previous night—except one person. “I won’t ask you, Mrs. Darragh, because I know you retire each night exactly at nine,” the chief interrogator said. Lydia Darragh smiled and said nothing. After the war she remarked that she was pleased that as a spy she had never had to tell a lie.
The British, of course, had a small army of spies working for them as well, and they constantly struggled to penetrate Washington’s operations. Toward the end of 1779, one of their Philadelphia spies wrote to Maj. John André, the charming, witty, artistically talented director of British intelligence: “Do you wish to have a useful hand in their army and to pay what you find his services worth? The exchange is 44 to 1.” The numbers refer to the vertiginous depreciation of the Continental dollar; British spies, too, wanted to be paid in hard money.
The Americans did their best to make trouble for André by spreading around Philadelphia and New York the rumor that he was given to molesting boys. It is not clear whether Washington was involved in these particular smears, and they hardly chime with André’s reputation for charming women, notably a Philadelphia belle named Peggy Shippen, who eventually married Gen. Benedict Arnold.
In any event, André was very successful at keeping tabs on the Americans. Surviving letters from his spies show him obtaining good estimates of American army strength in 1779. At one point Gen. Philip Schuyler made a motion in the Continental Congress that it leave Philadelphia because “they could do no business that was not instantly communicated” to the British.
His agents were so good he had to appeal for the lives of three arrested for communicating with the enemy.
André’s most successful agent was a woman named Ann Bates, a former schoolteacher who married a British soldier while the army was in Philadelphia. Disguised as a peddler, she wandered through the American camp, counted the cannon there, overheard conversations at Washington’s headquarters, and accurately predicted the American attack on the British base in Newport, Rhode Island, in 1778.
The intelligence war reached a climax, or something very close to one, between 1779 and 1781. American morale was sinking with the Continental currency, and trusting anyone became harder and harder. Washington could never be sure when a spy had been “turned” by British hard money, and the British tried to accelerate the decline of the paper dollar by printing and circulating millions of counterfeit bills.
Soon an astonished American was writing, “An ordinary horse is worth twenty thousand dollars.” In despair Congress stopped producing money; this brought the army’s commissary department to a halt. The Continental desertion rate rose, with veterans and sergeants among the chief fugitives.
Washington struggled to keep the British at bay with more disinformation about his dwindling strength. His spies had achieved such professionalism that he had to appeal to Gov. William Livingston of New Jersey to spare three men arrested in Elizabethtown for carrying on an illegal correspondence with the enemy. That was exactly what they had been doing—as double agents feeding the British disinformation.
The three spies stood heroically silent. Washington told Livingston they were willing to “bear the suspicion of being thought inimical.” But realism could not be carried too far; the Continental Army could not hang its own agents. Would the governor please do something? Livingston allowed the spies to escape, and intelligence documents show that three years later they were still at work.
By June 1780 agents had given the British high command accurate reports of the American army’s weakness in its Morristown camp. The main force had diminished to four thousand men; because of a shortage of fodder, there were no horses, which meant the artillery was immobilized. The British had just captured Charleston, South Carolina, and its garrison of five thousand, demoralizing the South. They decided a strike at Washington’s force could end the war, and they marshaled six thousand troops on Staten Island to deliver the blow.
A few hours before the attack, a furtive figure slipped ashore into New Jersey from Staten Island to warn the Continentals of the enemy buildup. He reached the officer in command in Elizabethtown, Col. Elias Dayton, and Dayton sent a rider off to Morristown with the news. Dayton and other members of the New Jersey Continental line, backed by local militia, were able to slow the British advance for the better part of a day, enabling Washington to get his army in motion and seize the high ground in the Short Hills, aborting the British plan.
Without Washington’s warning from a spy, the British might have ended the war at Morristown.
It was a very close call. Without the warning from that spy, the British army would certainly have come over the Short Hills, overwhelmed Washington’s four thousand men in Morristown, and captured their artillery. This probably would have ended the war.
After the royal army retreated to New York, word reached them that a French expeditionary force was landing in Newport, Rhode Island, to reinforce the struggling Americans. The British commander, Sir Henry Clinton, decided to attack before the French had a chance to recover from the rigors of the voyage and fortify.
This was the Culper network’s greatest moment. Robert Townsend, alias Culper Jr., discovered the plan shortly after Clinton put six thousand men aboard transports and sailed them to Huntington Bay on the north shore of Long Island. They waited there while British frigates scouted Newport Harbor to assess the size of the French squadron.
Townsend’s warning sent Washington’s disinformation machine into overdrive. Within twenty-four hours a double agent was in New York, handing the British top-secret papers, supposedly dropped by a careless courier, detailing a Washington plan to attack the city with every Continental soldier and militiaman in the middle states.
The British sent horsemen racing off to urge Sir Henry Clinton in Huntington Bay to return to New York with his six thousand men. Clinton, already discouraged by the British admiral’s lack of enthusiasm for his plan to take Newport, glumly agreed and sailed his soldiers back to their fortifications. There they waited for weeks for an assault that never materialized.
While Clinton was in Huntington Bay, he and two aides were made violently ill by tainted wine they drank with dinner aboard the flagship. He ordered the bottle seized and asked the physician general of the British army to examine the dregs in the glasses. The doctor said the wine was “strongly impregnated with arsenic.” During the night the bottle mysteriously disappeared, and Clinton was never able to confirm the assassination attempt or find the perpetrator. This may have been Washington’s way of getting even for the Hickey plot.
The main event in the later years of the intelligence war was the treason of Benedict Arnold in 1780. However, the American discovery of Arnold’s plot to sell the fortress at West Point to the British for six thousand pounds—about half a million dollars in modern money—was mostly luck. There was little that Benjamin Tallmadge or his agents could claim to their credit except having passed along a hint of a plot involving an American general a few weeks before.
There is no doubt that West Point would have been handed over and Benedict Arnold and John André given knighthoods if three wandering militiamen in Westchester County had not stopped André on his return to New York with the incriminating plans in his boot. The motive of these soldiers was not patriotism but robbery; Westchester was known as “the neutral ground,” and Loyalists and rebels alike wandered there in search of plunder.
Hanging John André was one of the most difficult things Washington had to do in the intelligence war. The major was the object of universal affection, and Alexander Hamilton and others on Washington’s staff urged him to find a way to commute the sentence. Washington grimly replied that he would do so only if the British handed over Arnold. That of course did not happen, and André died on the gallows. In the next twelve months, Washington made repeated attempts to capture Arnold. He ordered an American sergeant named Champe to desert and volunteer to join an American legion that Arnold was trying to create. To give Champe a convincing sendoff, Washington ordered a half a dozen cavalrymen to pursue him, without telling them he was a fake deserter. Champe arrived in the British lines with bullets chasing him.
Washington would seem to have liked these little touches of realism. Unusually fearless himself, he had once said as a young man that whistling bullets had “a charming sound.” One wonders if spies such as Honeyman and Champe agreed.
Soon Champe was a member of Arnold’s staff, living in the former general’s house on the Hudson River in New York. Through cooperating agents, Champe communicated a plan to knock Arnold unconscious when he went into his riverside garden to relieve himself one moonless night. A boatload of Americans would be waiting to carry him back to New Jersey and harsh justice.
On the appointed night the boat was there, and Arnold went to the garden as usual, but Champe was on a troopship in New York Harbor. Clinton had ordered two thousand men, including Arnold’s American legion, south to raid Virginia. Champe had to watch for an opportunity and deserted back to the American side.
Hanging John André was one of the most difficult things he had to do in the intelligence war.
Arnold’s defection badly upset American intelligence operations for months. He told the British what he knew of Washington’s spies in New York, and they made several arrests. Townsend quit spying for six months, to the great distress of Washington and Tallmadge.
The intelligence war continued during the year remaining until Yorktown. Washington’s reluctant decision to march south with the French army to try to trap a British army in that small Virginia tobacco port was accompanied by strenuous disinformation efforts intended to tie the British army to New York for as long as possible. In the line of march as the allied force moved south through New Jersey were some thirty large flatboats. British spies reported that the Americans were constructing large cooking ovens at several points near New York. Both seemed evidence of a plan to attack the city.
Benedict Arnold, now a British brigadier, begged Sir Henry Clinton to ignore this deception and give him six thousand men to attack the long, vulnerable American line of march. Clinton said no. He wanted to husband every available man in New York. By the time the British commander’s Philadelphia spies told him where Washington was actually going, it was too late. The royal army under Charles Lord Cornwallis surrendered after three weeks of pounding by heavy guns, the blow that finally ended the protracted war.
Even after the fighting wound down, intelligence activity went on. In the fall of 1782, a year after Yorktown, a French officer stationed in Morristown wrote, “Not a day has passed since we have drawn near the enemy that we have not had some news of them from our spies in New York.” For a final irony, the last British commander in America, Sir Guy Carleton, sent Washington a report from a British agent warning about a rebel plot to plunder New York and abuse Loyalists as the British army withdrew, and Washington sent in Major Tallmadge and a column of troops—not only to keep order but also to protect their agents, many of whom had earned enmity for appearing to be loyal to George III.
Among the American spies in New York was a huge Irish-American tailor named Hercules Mulligan who had sent Washington invaluable information. His greatest coup was a warning that the British planned to try to kidnap the American commander in 1780. Mulligan reported directly to Washington’s aide Col. Alexander Hamilton.
Another of the deepest agents was James Rivington, editor of the unctuously loyal New York Royal Gazette. He is believed to have stolen the top-secret signals of the British fleet, which the Americans passed on to the French in 1781. The knowledge may have helped the latter win the crucial naval battle off the Virginia capes that September, sealing Cornwallis’s fate at Yorktown.
The day after the British evacuated New York, Washington had breakfast with Hercules Mulligan—a way of announcing that he had been a patriot. He also paid a visit to James Rivington and apparently gave him a bag of gold coins. When he was composing his final expense account for submission to the Continental Congress with his resignation as Commander in Chief, Washington included from memory the contents of the bag of coins Robert Morris had rushed to him in late December 1776: 410 Spanish dollars, 2 English crowns, 10 shillings, and 2 sixpence. The circumstances under which he received it, Washington remarked, made it impossible for him ever to forget the exact amount of that crucial transfusion of hard money. It is another piece of evidence, barely needed at this point, that intelligence was a centerpiece of the strategy of protracted war—and that George Washington was a master of the game.
