American Revolutionary War
Benedict Arnold (January 14, 1741 [ O.S. January 3, 1740]   – June 14, 1801) was an American military officer who served as a general during the American Revolutionary War, fighting for the American Continental Army before defecting to the British in 1780. George Washington had given him his fullest trust and placed him in command of the fortifications at West Point, New York. Arnold planned to surrender the fort to British forces, but the plot was discovered in September 1780 and he fled to the British. His name quickly became a byword in the United States for treason and betrayal because he led the British army in battle against the very men whom he had once commanded. 
Arnold was born in the Connecticut Colony and was a merchant operating ships on the Atlantic Ocean when the war began in 1775. He joined the growing army outside Boston and distinguished himself through acts of intelligence and bravery. His actions included the Capture of Fort Ticonderoga in 1775, defensive and delaying tactics at the Battle of Valcour Island on Lake Champlain in 1776 which allowed American forces time to prepare New York's defenses, the Battle of Ridgefield, Connecticut (after which he was promoted to major general), operations in relief of the Siege of Fort Stanwix, and key actions during the pivotal Battles of Saratoga in 1777, in which he suffered leg injuries that halted his combat career for several years.
Arnold repeatedly claimed that he was passed over for promotion by the Continental Congress, while other officers obtained credit for some of his accomplishments.  Others in his military and political circles brought charges against him of corruption or other malfeasance, but most often he was acquitted in formal inquiries. Congress investigated his accounts, however, and concluded that he was indebted to Congress, and he borrowed heavily to maintain a lavish lifestyle.
Arnold mingled with Loyalist sympathizers in Philadelphia and married into one such family, to vivacious young Peggy Shippen. She was a close friend of British Major John André and kept in contact with him when he became head of the British espionage system in New York. Many historians point to her as facilitating Arnold's plans to switch sides; he opened secret negotiations with André, and Peggy relayed the messages. The British promised £20,000 for the capture of West Point, a major American stronghold; Washington greatly admired Arnold and gave him command of that fort in July 1780. His scheme was to surrender the fort to the British, but it was exposed in September 1780 when Patriot militia captured André carrying papers which revealed the plot. Arnold escaped and André was hanged.
Arnold received a commission as a brigadier general in the British Army, an annual pension of £360, and a lump sum of over £6,000.  He led British forces on raids in Virginia, and they burned much of New London, Connecticut to the ground and slaughtered surrendering forces after the Battle of Groton Heights—just a few miles downriver from the town where he had grown up. In the winter of 1782, he and Peggy moved to London, England. He was well received by King George III and the Tories but frowned upon by the Whigs and most Army officers. In 1787, he moved to Canada to a merchant business with his sons Richard and Henry. He was extremely unpopular there and returned to London permanently in 1791.

Benedict Arnold was born a British subject, the second of six children of Benedict Arnold (1683–1761) and Hannah Waterman King in Norwich, Connecticut Colony on January 14, 1741.   He was named after his great-grandfather Benedict Arnold, an early governor of the Colony of Rhode Island, as were his father and grandfather and an older brother who died in infancy.  Only he and his sister Hannah survived to adulthood; his other siblings succumbed to yellow fever in childhood.  His siblings were, in order of birth: Benedict (August 15, 1738 – April 30, 1739), Hannah (December 9, 1742 – August 11, 1803), Mary (June 4, 1745 – September 10, 1753), Absolom (April 4, 1747 – July 22, 1750), and Elizabeth (November 19, 1749 – September 29, 1755). Arnold was a descendant of John Lothropp through his maternal grandmother, an ancestor of six presidents. 
Arnold's father was a successful businessman, and the family moved in the upper levels of Norwich society. He was enrolled in a private school in nearby Canterbury, Connecticut when he was 10, with the expectation that he would eventually attend Yale University. However, the deaths of his siblings two years later may have contributed to a decline in the family fortunes, since his father took up drinking. By the time that he was 14, there was no money for private education. His father's alcoholism and ill health kept him from training Arnold in the family mercantile business, but his mother's family connections secured an apprenticeship for him with her cousins Daniel and Joshua Lathrop, who operated a successful apothecary and general merchandise trade in Norwich.  His apprenticeship with the Lathrops lasted seven years. 
Arnold was very close to his mother, who died in 1759. His father's alcoholism worsened after her death, and the youth took on the responsibility of supporting his father and younger sister. His father was arrested on several occasions for public drunkenness, was refused communion by his church, and died in 1761. 
French and Indian War
In 1755, Arnold was attracted by the sound of a drummer and attempted to enlist in the provincial militia for service in the French and Indian War, but his mother refused permission.  In 1757 when he was 16, he did enlist in the Connecticut militia, which marched off toward Albany, New York and Lake George. The French had besieged Fort William Henry in northeastern New York, and their Indian allies had committed atrocities after their victory. Word of the siege's disastrous outcome led the company to turn around, and Arnold served for only 13 days.  A commonly accepted story that he deserted from militia service in 1758  is based on uncertain documentary evidence. 
Arnold established himself in business in 1762 as a pharmacist and bookseller in New Haven, Connecticut with the help of the Lathrops.  He was hardworking and successful, and was able to rapidly expand his business. In 1763, he repaid money that he had borrowed from the Lathrops,  repurchased the family homestead that his father had sold when deeply in debt, and re-sold it a year later for a substantial profit. In 1764, he formed a partnership with Adam Babcock, another young New Haven merchant. They bought three trading ships, using the profits from the sale of his homestead, and established a lucrative West Indies trade.
During this time, Arnold brought his sister Hannah to New Haven and established her in his apothecary to manage the business in his absence. He traveled extensively in the course of his business throughout New England and from Quebec to the West Indies, often in command of one of his own ships.  On one of his voyages, he fought a duel in Honduras with a British sea captain who had called him a "damned Yankee, destitute of good manners or those of a gentleman".   The captain was wounded in the first exchange of gunfire, and he apologized when Arnold threatened to aim to kill on the second. 
The Sugar Act of 1764 and the Stamp Act of 1765 severely curtailed mercantile trade in the colonies.  The Stamp Act prompted Arnold to join the chorus of voices in opposition, and also led to his entry into the Sons of Liberty, a secret organization that was not afraid to oppose implementation of those and other unpopular Parliamentary measures.  Arnold initially took no part in any public demonstrations but, like many merchants, continued to trade as if the Stamp Act did not exist, in effect becoming a smuggler in defiance of the act. He also faced financial ruin, falling £16,000 in debt, with creditors spreading rumors of his insolvency to the point where he took legal action against them.  On the night of January 28, 1767, Arnold and members of his crew roughed up a man suspected of attempting to inform authorities of Arnold's smuggling. Arnold was convicted of disorderly conduct and fined the relatively small amount of 50 shillings; publicity of the case and widespread sympathy for his view probably contributed to the light sentence. 
On February 22, 1767, Arnold married Margaret Mansfield, daughter of Samuel Mansfield, the sheriff of New Haven and a fellow member in the local Masonic Lodge.  Their son Benedict was born the following year,  and was followed by brothers Richard in 1769 and Henry in 1772.  Margaret died on June 19, 1775 while Arnold was at Fort Ticonderoga following its capture.  The household was dominated by Arnold's sister Hannah, even while Margaret was alive. Arnold benefited from his relationship with Mansfield, who became a partner in his business and used his position as sheriff to shield him from creditors. 
Arnold was in the West Indies when the Boston Massacre took place on March 5, 1770. He wrote that he was "very much shocked" and wondered "good God, are the Americans all asleep and tamely giving up their liberties, or are they all turned philosophers, that they don't take immediate vengeance on such miscreants?" 
American Revolutionary War
Siege of Boston and Fort Ticonderoga
Arnold began the war as a captain in the Connecticut Colony militia, a position to which he was elected in March 1775. His company marched northeast the following month to assist in the siege of Boston that followed the Battles of Lexington and Concord. He proposed an action to the Massachusetts Committee of Safety to seize Fort Ticonderoga in upstate New York, which he knew was poorly defended. They issued him a colonel's commission on May 3, 1775, and he immediately rode off to Castleton in the disputed New Hampshire Grants ( Vermont) in time to participate with Ethan Allen and his men in the capture of Fort Ticonderoga. He followed up that action with a bold raid on Fort Saint-Jean on the Richelieu River north of Lake Champlain. A Connecticut militia force arrived at Ticonderoga in June; Arnold had a dispute with its commander over control of the fort, and resigned his Massachusetts commission. He was on his way home from Ticonderoga when he learned that his wife had died earlier in June. 
The Second Continental Congress authorized an invasion of Quebec, in part on the urging of Arnold—but he was passed over for command of the expedition. He then went to Cambridge, Massachusetts and suggested to George Washington a second expedition to attack Quebec City via a wilderness route through Maine. He received a colonel's commission in the Continental Army for this expedition and left Cambridge in September 1775 with 1,100 men. He arrived before Quebec City in November, after a difficult passage in which 300 men turned back and another 200 died en route. He and his men were joined by Richard Montgomery's small army and participated in the December 31 assault on Quebec City in which Montgomery was killed and Arnold's leg was shattered. His chaplain Rev. Samuel Spring carried him to the makeshift hospital at the Hôtel Dieu. Arnold was promoted to brigadier general for his role in reaching Quebec, and he maintained an ineffectual siege of the city until he was replaced by Major General David Wooster in April 1776. 
Arnold then traveled to Montreal where he served as military commander of the city until forced to retreat by an advancing British army that had arrived at Quebec in May. He presided over the rear of the Continental Army during its retreat from Saint-Jean, where he was reported by James Wilkinson to be the last person to leave before the British arrived. He then directed the construction of a fleet to defend Lake Champlain, which was overmatched and defeated in the October 1776 Battle of Valcour Island. However, his actions at Saint-Jean and Valcour Island played a notable role in delaying the British advance against Ticonderoga until 1777. 
During these actions, Arnold made a number of friends and a larger number of enemies within the army power structure and in Congress. He had established a decent relationship with George Washington, as well as Philip Schuyler and Horatio Gates, both of whom had command of the army's Northern Department during 1775 and 1776.  However, an acrimonious dispute with Moses Hazen, commander of the 2nd Canadian Regiment, boiled into Hazen's court martial at Ticonderoga during the summer of 1776. Only action by Arnold's superior at Ticonderoga prevented his own arrest on countercharges leveled by Hazen.  He also had disagreements with John Brown and James Easton, two lower-level officers with political connections that resulted in ongoing suggestions of improprieties on his part. Brown was particularly vicious, publishing a handbill which claimed of Arnold, "Money is this man's God, and to get enough of it he would sacrifice his country". 
Rhode Island and Philadelphia
General Washington assigned Arnold to the defense of Rhode Island following the British seizure of Newport in December 1776, where the militia were too poorly equipped to even consider an attack on the British.  He took the opportunity to visit his children while near his home in New Haven, and he spent much of the winter socializing in Boston, where he unsuccessfully courted a young belle named Betsy Deblois.  In February 1777, he learned that he had been passed over by Congress for promotion to major general. Washington refused his offer to resign, and wrote to members of Congress in an attempt to correct this, noting that "two or three other very good officers" might be lost if they persisted in making politically motivated promotions. 
Arnold was on his way to Philadelphia to discuss his future when he was alerted that a British force was marching toward a supply depot in Danbury, Connecticut. He organized the militia response, along with David Wooster and Connecticut militia General Gold Selleck Silliman. He led a small contingent of militia attempting to stop or slow the British return to the coast in the Battle of Ridgefield, and was again wounded in his left leg.
He then continued on to Philadelphia where he met with members of Congress about his rank. His action at Ridgefield, coupled with the death of Wooster due to wounds sustained in the action, resulted in his promotion to major general, although his seniority was not restored over those who had been promoted before him.  Amid negotiations over that issue, Arnold wrote out a letter of resignation on July 11, the same day that word arrived in Philadelphia that Fort Ticonderoga had fallen to the British. Washington refused his resignation and ordered him north to assist with the defense there. 
Arnold arrived in Schuyler's camp at Fort Edward, New York on July 24. On August 13, Schuyler dispatched him with a force of 900 to relieve the siege of Fort Stanwix, where he succeeded in a ruse to lift the siege. He sent an Indian messenger into the camp of British Brigadier General Barry St. Leger with news that the approaching force was much larger and closer than it actually was; this convinced St. Leger's Indian allies to abandon him, forcing him to give up the effort. 
Arnold returned to the Hudson where General Gates had taken over command of the American army, which had retreated to a camp south of Stillwater.  He then distinguished himself in both Battles of Saratoga, even though General Gates removed him from field command after the first battle, following a series of escalating disagreements and disputes that culminated in a shouting match.  During the fighting in the second battle, Arnold disobeyed Gates' orders and took to the battlefield to lead attacks on the British defenses. He was again severely wounded in the left leg late in the fighting. Arnold said that it would have been better had it been in the chest instead of the leg.  Burgoyne surrendered ten days after the second battle on October 17, 1777. Congress restored Arnold's command seniority in response to his valor at Saratoga.  However, he interpreted the manner in which they did so as an act of sympathy for his wounds, and not an apology or recognition that they were righting a wrong. 
Arnold spent several months recovering from his injuries. He had his leg crudely set, rather than allowing it to be amputated, leaving it 2 inches (5 cm) shorter than the right. He returned to the army at Valley Forge, Pennsylvania in May 1778 to the applause of men who had served under him at Saratoga.  There he participated in the first recorded Oath of Allegiance, along with many other soldiers, as a sign of loyalty to the United States. 
Residence in Philadelphia
The British withdrew from Philadelphia in June 1778, and Washington appointed Arnold military commander of the city.  Historian John Shy states:
- Washington then made one of the worst decisions of his career, appointing Arnold as military governor of the rich, politically divided city. No one could have been less qualified for the position. Arnold had amply demonstrated his tendency to become embroiled in disputes, as well as his lack of political sense. Above all, he needed tact, patience, and fairness in dealing with a people deeply marked by months of enemy occupation. 
Arnold began planning to capitalize financially on the change in power in Philadelphia, even before the Americans reoccupied their city. He engaged in a variety of business deals designed to profit from war-related supply movements and benefiting from the protection of his authority.  Such schemes were not uncommon among American officers, but Arnold's schemes were sometimes frustrated by powerful local politicians such as Joseph Reed, who eventually amassed enough evidence to publicly air charges against him. Arnold demanded a court martial to clear the charges, writing to Washington in May 1779: "Having become a cripple in the service of my country, I little expected to meet ungrateful returns". 
Arnold lived extravagantly in Philadelphia and was a prominent figure on the social scene. During the summer of 1778, he met Peggy Shippen, the 18 year-old daughter of Judge Edward Shippen (III), a Loyalist sympathizer who had done business with the British while they occupied the city;  Peggy had been courted by British Major John André during the British occupation of Philadelphia.  She married Arnold on April 8, 1779.  Shippen and her circle of friends had found methods of staying in contact with paramours across the battle lines, despite military bans on communication with the enemy.  Some of this communication was effected through the services of Joseph Stansbury, a Philadelphia merchant. 
Plotting to change sides
Historians have identified many possible factors contributing to Arnold's treason, while some debate their relative importance. According to W. D. Wetherell, he was:
- among the hardest human beings to understand in American history. Did he become a traitor because of all the injustice he suffered, real and imagined, at the hands of the Continental Congress and his jealous fellow generals? Because of the constant agony of two battlefield wounds in an already gout-ridden leg? From psychological wounds received in his Connecticut childhood when his alcoholic father squandered the family’s fortunes? Or was it a kind of extreme midlife crisis, swerving from radical political beliefs to reactionary ones, a change accelerated by his marriage to the very young, very pretty, very Tory Peggy Shippen? 
Wetherell says that the shortest explanation for his treason is that he "married the wrong person." 
Arnold was a difficult personality, extremely ambitious and jealous, making many enemies and getting into troubles wherever he went in the United States, Britain, or Canada. He knew that he was distrusted and disliked by senior military officers on both sides. Washington was one of the few who genuinely liked and admired him, but Arnold thought that Washington betrayed him.
Arnold was greedy and a spendthrift, and heavily in debt to London financiers. The British promise of £20,000 for the capture of West Point would have solved his financial crisis. In Philadelphia, he mingled with high society in a very expensive fashion, including many prominent families who had recently been quite friendly to the British during their occupation. The Shippen family was one of them, and he married their vivacious young daughter Peggy. She previously had been courted by British major John André, who later was the head of the British espionage system. André was in charge of handling Arnold for the General Clinton and the British high command. Peggy egged on her husband and collaborated in his treason, acting as a courier to André in New York City. Arnold had been badly wounded twice in battle and had lost his business in Connecticut, and that made him profoundly bitter. He grew jealous of several rival generals who had been promoted ahead of him and given honors which he thought he deserved. Especially galling was a long feud with the civil authorities in Philadelphia that led to his court-martial.
Arnold was convicted on two minor charges of using his authority to make a profit. He was given a light reprimand by General Washington, which heightened his sense of betrayal, but he had already opened negotiations with the British before his court martial began. He later said in his own defense that he was loyal to his true beliefs, yet he lied at the same time by insisting that Peggy was totally innocent and ignorant of his plans.  
As early as 1778, there were signs that Arnold was unhappy with his situation and pessimistic about the country's future. On November 10, 1778, General Nathanael Greene wrote to General John Cadwalader, "I am told General Arnold is become very unpopular among you oweing to his associateing too much with the Tories."  A few days later, Greene received a letter from Arnold in which he lamented over the "deplorable" and "horrid" situation of the country at that particular moment, citing the depreciating currency, disaffection of the army, and internal fighting in Congress, while predicting "impending ruin" if things did not change soon. 
Biographer Nathaniel Philbrick argues:
- Peggy Shippen… did have a significant role in the plot. She exerted powerful influence on her husband, who is said to have been his own man but who actually was swayed by his staff and certainly by his wife. Peggy came from a loyalist family in Philadelphia; she had many ties to the British. She… was the conduit for information to the British. 
Early in May 1779, Arnold met with Philadelphia merchant Joseph Stansbury  who then "went secretly to New York with a tender of [Arnold's] services to Sir Henry Clinton".  Stansbury ignored instructions from Arnold to involve no one else in the plot, and he crossed the British lines and went to see Jonathan Odell in New York. Odell was a Loyalist working with William Franklin, the last colonial governor of New Jersey and the son of Benjamin Franklin. On May 9, Franklin introduced Stansbury to Major André, who had just been named the British spy chief.  This was the beginning of a secret correspondence between Arnold and André, sometimes using his wife Peggy as a willing intermediary, that culminated more than a year later with Arnold's change of sides. 
André conferred with General Clinton, who gave him broad authority to pursue Arnold's offer. André then drafted instructions to Stansbury and Arnold.  This initial letter opened a discussion on the types of assistance and intelligence that Arnold might provide, and included instructions for how to communicate in the future. Letters were to be passed through the women's circle that Peggy Arnold was a part of, but only Peggy would be aware that some letters contained instructions that were to be passed on to André, written in both code and invisible ink, using Stansbury as the courier. 
By July 1779, Benedict Arnold was providing the British with troop locations and strengths, as well as the locations of supply depots, all the while negotiating over compensation. At first, he asked for indemnification of his losses and £10,000, an amount that the Continental Congress had given Charles Lee for his services in the Continental Army.  General Clinton was pursuing a campaign to gain control of the Hudson River Valley, and was interested in plans and information on the defenses of West Point and other defenses on the Hudson River. He also began to insist on a face-to-face meeting, and suggested to Arnold that he pursue another high-level command.  By October 1779, the negotiations had ground to a halt.  Furthermore, Patriot mobs were scouring Philadelphia for Loyalists, and Arnold and the Shippen family were being threatened. Arnold was rebuffed by Congress and by local authorities in requests for security details for himself and his in-laws. 
The court martial began meeting on June 1, 1779 to consider the charges against Benedict Arnold, but it was delayed until December 1779 by General Clinton's capture of Stony Point, New York, throwing the army into a flurry of activity to react.  Several members on the panel of judges were ill-disposed toward Arnold over actions and disputes earlier in the war, yet Arnold was cleared of all but two minor charges on January 26, 1780.  Arnold worked over the next few months to publicize this fact; however, George Washington published a formal rebuke of his behavior in early April, just one week after he had congratulated Arnold on the March 19 birth of his son Edward Shippen Arnold: 
The Commander-in-Chief would have been much happier in an occasion of bestowing commendations on an officer who had rendered such distinguished services to his country as Major General Arnold; but in the present case, a sense of duty and a regard to candor oblige him to declare that he considers his conduct [in the convicted actions] as imprudent and improper. 
Shortly after Washington's rebuke, a Congressional inquiry into Arnold's expenditures concluded that he had failed to fully account for his expenditures incurred during the Quebec invasion, and that he owed the Congress some £1,000, largely because he was unable to document them.  A significant number of these documents had been lost during the retreat from Quebec. Angry and frustrated, Arnold resigned his military command of Philadelphia in late April. 
Offer to surrender West Point
Early in April, Philip Schuyler had approached Arnold with the possibility of giving him the command at West Point. Discussions had not borne fruit between Schuyler and Washington by early June. Arnold reopened the secret channels with the British, informing them of Schuyler's proposals and including Schuyler's assessment of conditions at West Point. He also provided information on a proposed French-American invasion of Quebec that was to go up the Connecticut River (Arnold did not know that this proposed invasion was a ruse intended to divert British resources). On June 16, Arnold inspected West Point while on his way home to Connecticut to take care of personal business, and he sent a highly detailed report through the secret channel.  When he reached Connecticut, Arnold arranged to sell his home there and began transferring assets to London through intermediaries in New York. By early July, he was back in Philadelphia, where he wrote another secret message to Clinton on July 7 which implied that his appointment to West Point was assured and that he might even provide a "drawing of the works ... by which you might take [West Point] without loss". 
Major André returned victorious from the Siege of Charleston on June 18, and both he and General Clinton were immediately caught up in this news. Clinton was concerned that Washington's army and the French fleet would join in Rhode Island, and he again fixed on West Point as a strategic point to capture. André had spies and informers keeping track of Arnold to verify his movements. Excited by the prospects, Clinton informed his superiors of his intelligence coup, but failed to respond to Arnold's July 7 letter. 
Benedict Arnold next wrote a series of letters to Clinton, even before he might have expected a response to the July 7 letter. In a July 11 letter, he complained that the British did not appear to trust him, and threatened to break off negotiations unless progress was made. On July 12, he wrote again, making explicit the offer to surrender West Point, although his price rose to £20,000 (in addition to indemnification for his losses), with a £1,000 down payment to be delivered with the response. These letters were delivered by Samuel Wallis, another Philadelphia businessman who spied for the British, rather than by Stansbury. 
Command at West Point
On August 3, 1780, Arnold obtained command of West Point. On August 15, he received a coded letter from André with Clinton's final offer: £20,000 and no indemnification for his losses. Neither side knew for some days that the other was in agreement with that offer, due to difficulties in getting the messages across the lines. Arnold's letters continued to detail Washington's troop movements and provide information about French reinforcements that were being organized. On August 25, Peggy finally delivered to him Clinton's agreement to the terms. 
Arnold's command at West Point also gave him authority over the entire American-controlled Hudson River, from Albany down to the British lines outside New York City. While en route to West Point, Arnold renewed an acquaintance with Joshua Hett Smith, who had spied for both sides and who owned a house near the western bank of the Hudson about 15 miles south of West Point. 
Once Arnold established himself at West Point, he began systematically weakening its defenses and military strength. Needed repairs were never ordered on the chain across the Hudson. Troops were liberally distributed within Arnold's command area (but only minimally at West Point itself) or furnished to Washington on request. He also peppered Washington with complaints about the lack of supplies, writing, "Everything is wanting."  At the same time, he tried to drain West Point's supplies so that a siege would be more likely to succeed. His subordinates, some long-time associates, grumbled about Arnold's unnecessary distribution of supplies and eventually concluded that he was selling them on the black market for personal gain. 
On August 30, Arnold sent a letter accepting Clinton's terms and proposing a meeting to André through yet another intermediary: William Heron, a member of the Connecticut Assembly whom he thought he could trust. In an ironic twist, Heron went into New York unaware of the significance of the letter and offered his own services to the British as a spy. He then took the letter back to Connecticut, suspicious of Arnold's actions, where he delivered it to the head of the Connecticut militia. General Parsons laid it aside, seeing a letter written as a coded business discussion. Four days later, Arnold sent a ciphered letter with similar content into New York through the services of the wife of a prisoner of war.  Eventually, a meeting was set for September 11 near Dobb's Ferry. This meeting was thwarted when British gunboats in the river fired on his boat, not being informed of his impending arrival. 
Arnold and André finally met on September 21 at the Joshua Hett Smith House. On the morning of September 22, the outpost at Verplanck's Point under command of Col. James Livingston fired on HMS Vulture, the ship that was intended to carry André back to New York. This action did sufficient damage that she retreated downriver, forcing André to return to New York overland. Arnold wrote out passes for André so that he would be able to pass through the lines, and he also gave him plans for West Point. 
André was captured near Tarrytown, New York on Saturday, September 23 by three Westchester militiamen named John Paulding, Isaac Van Wart, and David Williams.  They found the papers exposing the plot to capture West Point and sent them to Washington, and Arnold's intentions came to light after Washington examined them.  Meanwhile, André convinced the unsuspecting Colonel John Jameson, to whom he was delivered, to send him back to Arnold at West Point. However, Major Benjamin Tallmadge, a member of the Culper Ring established under Washington's orders,  insisted that Jameson order the prisoner to be intercepted and brought back. Jameson reluctantly recalled the lieutenant who had been delivering André into Arnold's custody, but then sent the same lieutenant as a messenger to notify Arnold of André's arrest. 
Arnold learned of André's capture the morning of September 24 when he received Jameson's message, and he learned that Jameson had sent Washington the papers which André was carrying. He received the letter while waiting for Washington, with whom he had planned to have breakfast.  He immediately hastened to the shore and ordered bargemen to row him downriver to where HMS Vulture was anchored, which then took him to New York.  From the ship, he wrote a letter to Washington,  requesting that Peggy be given safe passage to her family in Philadelphia—a request that Washington granted. 
Washington remained calm when he was presented with evidence of Arnold's activities. He did, however, investigate its extent, and suggested that he was willing to exchange André for Arnold during negotiations with General Clinton concerning André's fate. Clinton refused this suggestion; after a military tribunal, André was hanged at Tappan, New York on October 2. Washington also infiltrated men into New York in an attempt to capture Arnold. This plan very nearly succeeded, but failed when Arnold changed living quarters prior to sailing for Virginia in December. 
Arnold justified his actions in an open letter titled " To the Inhabitants of America", published in newspapers in October 1780.  He also wrote in the letter to Washington requesting safe passage for Peggy: "Love to my country actuates my present conduct, however it may appear inconsistent to the world, who very seldom judge right of any man's actions." 
After switching sides
British Army service
Raids in Virginia and Connecticut Colonies
The British gave Arnold a brigadier general's commission with an annual income of several hundred pounds, but they paid him only £6,315 plus an annual pension of £360 because his plot had failed.  In December 1780, he led a force of 1,600 troops into Virginia under orders from Clinton, where he captured Richmond by surprise and then went on a rampage through Virginia, destroying supply houses, foundries, and mills.  This activity brought out Virginia's militia led by Colonel Sampson Mathews, and Arnold eventually retreated to Portsmouth to be reinforced or to evacuate. 
The pursuing American army included the Marquis de Lafayette, who was under orders from Washington to hang Arnold summarily if he was captured. British reinforcements arrived in late March led by William Phillips who served under Burgoyne at Saratoga. Phillips led further raids across Virginia, including a defeat of Baron von Steuben at Petersburg, but he died of fever on May 12, 1781. Arnold commanded the army only until May 20, when Lord Cornwallis arrived with the southern army and took over. One colonel wrote to Clinton concerning Arnold: "There are many officers who must wish some other general in command."  Cornwallis ignored Arnold's advice to locate a permanent base away from the coast, advice that might have averted his surrender at Yorktown. 
On his return to New York in June, Arnold made a variety of proposals for attacks on economic targets to force the Americans to end the war. Clinton was uninterested in most of his aggressive ideas, but finally authorized him to raid the port of New London, Connecticut. He led a force of more than 1,700 men which burned most of New London to the ground on September 4, causing damage estimated at $500,000. . They also attacked captured Fort Griswold across the river in Groton, Connecticut, slaughtering the Americans after they surrendered following the Battle of Groton Heights—and all these things were done just a few miles down the Thames River from Norwich, Connecticut where Arnold grew up. However, British casualties were high; nearly one quarter of the force was killed or wounded, and Clinton declared that he could ill afford any more such victories. 
British surrender and exile in England
Even before Cornwallis's surrender in October, Arnold had requested permission from Clinton to go to England to give Lord George Germain his thoughts on the war in person.  He renewed that request when he learned of the surrender, which Clinton then granted. On December 8, 1781, Arnold and his family left New York for England. 
In London, Arnold aligned himself with the Tories, advising Germain and King George III to renew the fight against the Americans. In the House of Commons, Edmund Burke expressed the hope that the government would not put Arnold "at the head of a part of a British army" lest "the sentiments of true honour, which every British officer [holds] dearer than life, should be afflicted."  The anti-war Whigs had gained the upper hand in Parliament, and Germain was forced to resign, with the government of Lord North falling not long after. 
Arnold then applied to accompany General Carleton, who was going to New York to replace Clinton as commander-in-chief, but the request went nowhere.  Other attempts all failed to gain positions within the government or the British East India Company over the next few years, and he was forced to subsist on the reduced pay of non-wartime service.  His reputation also came under criticism in the British press, especially when compared to Major André who was celebrated for his patriotism. One critic said that he was a "mean mercenary, who, having adopted a cause for the sake of plunder, quits it when convicted of that charge."  George Johnstone turned him down for a position in the East India Company and explained: "Although I am satisfied with the purity of your conduct, the generality do not think so. While this is the case, no power in this country could suddenly place you in the situation you aim at under the East India Company." 
New business opportunities
In 1785, Benedict Arnold and his son Richard moved to Saint John, New Brunswick, where they speculated in land and established a business doing trade with the West Indies. Arnold purchased large tracts of land in the Maugerville area, and acquired city lots in Saint John and Fredericton.  Delivery of his first ship the Lord Sheffield was accompanied by accusations from the builder that Arnold had cheated him; Arnold claimed that he had merely deducted the contractually agreed amount when the ship was delivered late.  After her first voyage, Arnold returned to London in 1786 to bring his family to Saint John. While there, he disentangled himself from a lawsuit over an unpaid debt that Peggy had been fighting while he was away, paying £900 to settle a £12,000 loan that he had taken while living in Philadelphia.  The family moved to Saint John in 1787, where Arnold created an uproar with a series of bad business deals and petty lawsuits.  The most serious of these was a slander suit which he won against a former business partner; and following this, townspeople burned him in effigy in front of his house, as Peggy and the children watched.  The family left Saint John to return to London in December 1791. 
In July 1792, Benedict Arnold fought a bloodless duel with the Earl of Lauderdale after the Earl impugned his honor in the House of Lords.  With the outbreak of the French Revolution, Arnold outfitted a privateer, while continuing to do business in the West Indies, even though the hostilities increased the risk. He was imprisoned by French authorities on Guadeloupe amid accusations of spying for the British, and narrowly eluded hanging by escaping to the blockading British fleet after bribing his guards. He helped organize militia forces on British-held islands, receiving praise from the landowners for his efforts on their behalf. He hoped that this work would earn him wider respect and a new command; instead, it earned him and his sons a land-grant of 15,000 acres (6,100 ha) in Upper Canada,  near present-day Renfrew, Ontario. 
In January 1801, Benedict Arnold's health began to decline.  He had suffered from gout since 1775,  and the condition attacked his unwounded leg to the point where he was unable to go to sea. The other leg ached constantly, and he walked only with a cane. His physicians diagnosed him as having dropsy, and a visit to the countryside only temporarily improved his condition. He died after four days of delirium on June 14, 1801, at the age of 60.  Legend has it that, when he was on his deathbed, he said, "Let me die in this old uniform in which I fought my battles. May God forgive me for ever having put on another,"  but this story may be apocryphal.  Arnold was buried at St. Mary's Church, Battersea in London, England.  As a result of a clerical error in the parish records, his remains were removed to an unmarked mass grave during church renovations a century later.  His funeral procession boasted "seven mourning coaches and four state carriages";  the funeral was without military honors. 
Benedict Arnold left a small estate, reduced in size by his debts, which Peggy undertook to clear.   Among his bequests were considerable gifts to one John Sage, perhaps an illegitimate son or grandson. 
Infamy in the United States
Benedict Arnold's name became synonymous with traitor soon after his betrayal became public. Biblical themes were often invoked; Benjamin Franklin wrote that " Judas sold only one man, Arnold three millions", and Alexander Scammell described his actions as "black as hell".  In his home town of Norwich, someone scrawled the word "Traitor" next to his record of birth at City Hall. Additionally, the gravestones were destroyed of all but his mother. 
Early biographers attempted to describe Arnold's entire life in terms of treacherous or morally questionable behavior. The first major biography of his life was The Life and Treason of Benedict Arnold, published in 1832 by historian Jared Sparks; it was particularly harsh in showing how Arnold's treacherous character was formed out of childhood experiences.  George Canning Hill authored a series of moralistic biographies in the mid-19th century and began his 1865 biography of Arnold: "Benedict, the Traitor, was born…".  Social historian Brian Carso notes that, as the 19th century progressed, the story of Arnold's betrayal was portrayed with near-mythical proportions as a part of the national creation story. It was invoked again as sectional conflicts increased in the years before the American Civil War. Washington Irving used it as part of an argument against dismemberment of the union in his 1857 Life of George Washington, pointing out that the unity of New England and the southern states which led to independence was made possible in part by holding West Point.  Jefferson Davis and other southern secessionist leaders were unfavorably compared to Arnold, implicitly and explicitly likening the idea of secession to treason. Harper's Weekly published an article in 1861 describing Confederate leaders as "a few men directing this colossal treason, by whose side Benedict Arnold shines white as a saint." 
Fictional invocations of Benedict Arnold's name carry strongly negative overtones.  A moralistic children's tale entitled "The Cruel Boy" was widely circulated in the 19th century. It described a boy who stole eggs from birds' nests, pulled wings off insects, and engaged in other sorts of wanton cruelty, who then grew up to become a traitor to his country.  The boy is not identified until the end of the story, when his place of birth is given as Norwich, Connecticut, and his name is given as Benedict Arnold.  However, not all depictions of Arnold were so negative. Some theatrical treatments of the 19th century explored his duplicity, seeking to understand rather than demonize it. 
Canadian historians have treated Arnold as a relatively minor figure. His difficult time in New Brunswick led historians to summarize it as full of "controversy, resentment, and legal entanglements" and to conclude that he was disliked by both Americans and Loyalists living there.  Historian Barry Wilson points out that Arnold's descendants established deep roots in Canada, becoming leading settlers in Upper Canada and Saskatchewan.  His descendants who adopted the Arnold surname are spread across Canada, most of all those of John Sage.

- Henry Arnold (1772–1826) (Lieutenant, Loyalist American Legion cavalry)
and with Peggy Shippen, he raised a family also active in the British Army:

- Sophia Matilda Arnold (1785–1828) (married Colonel Pownall Phipps)
- William Fitch Arnold (1794–1846) ( Captain, 9th Queen's Royal Lancers)
There is a memorial to Arnold on the Saratoga battlefield preserved within Saratoga National Historical Park which does not mention his name, donated by Civil War General John Watts DePeyster. The inscription on the Boot Monument reads: "In memory of the most brilliant soldier of the Continental army, who was desperately wounded on this spot, winning for his countrymen the decisive battle of the American Revolution, and for himself the rank of Major General."  The victory monument at Saratoga has four niches, three of which are occupied by statues of Generals Gates, Schuyler, and Morgan. The fourth niche is empty. 
There are plaques on the grounds of the United States Military Academy at West Point, New York commemorating all of the generals who served in the Revolution. One plaque bears only a rank and a date but no name: "major general… born 1740".   A historical marker in Danvers, Massachusetts commemorates Arnold's 1775 expedition to Quebec.  There are also historical markers bearing his name at Wyman Lake Rest Area on US-201 north of Moscow, Maine, on the western bank of Lake Champlain, New York, and two in Skowhegan, Maine. 
The house where Arnold lived at 62 Gloucester Place in central London bears a plaque describing him as an "American Patriot".  He was buried at St Mary's Church, Battersea, England which has a commemorative stained glass window.  The faculty club at the University of New Brunswick, Fredericton has a Benedict Arnold Room in which letters written by Arnold hang on the walls.

Sage's gravestone indicates that he was born on April 14, 1786, a date roughly confirmed by Arnold's will, which stated that Sage was 14 when Arnold wrote it in 1800. Arnold arrived in New Brunswick in December 1785, so Sage's mother could not have been from there. Wilson believes that the explanation most consistent with the available documentation is that Sage was either the result of a liaison before Arnold left England or that he was Arnold's grandson by one of his older children.
