Military career of Benedict Arnold, 1777–1779

Following the defeat on Lake Champlain, Arnold accompanied Major General Horatio Gates as he led a portion of the army at Ticonderoga south to assist General Washington in the defense of New Jersey.[13] On December 7, 1776, a large British force under Lieutenant General Henry Clinton occupied Newport, Rhode Island.[14] In response Washington ordered Arnold to go back to New England to raise militia and coordinate the defense of Rhode Island. Arnold was made Deputy Commander of the Eastern Department of the Continental Army under Major General Joseph Spencer, and left Washington's camp in Pennsylvania on December 22.[15]

Arnold, who had not seen his family for over a year, spent a week visiting with them in New Haven, during which he successfully urged Washington and Henry Knox, the army's chief of artillery, to raise an artillery regiment for John Lamb and Eleazer Oswald, two Connecticut men who had served with him on the expedition to Quebec.[16] He arrived at Providence on January 12, 1777, to lead the defense against the British at Newport. There were 4,000 Rhode Island militia mobilized, and both the governor and Arnold's commander, General Spencer, were itching to drive the British out of Newport.[14] Arnold developed a plan for driving the British from Newport, but found that the militia were so poorly equipped and supplied that offensive operations were, in his view, ill-advised.[14][17]

In February 1777 Arnold met and seriously courted the daughter of a well known Boston Loyalist, Betsy Deblois, described as the belle of Boston. "The heavenly Miss Deblois" refused his repeated proposals, likely because she was only fifteen.[19] When he returned to Providence he learned that he was one of several officers that had been passed over for promotion to major general by Congress. The reasons for this were largely political in nature, but it is unlikely that his prospects were helped by Horatio Gates' delivery of a petition by John Brown making many accusations against Arnold just one month before Congress took up the matter.[20] Gates was apparently upset that Washington had given the Rhode Island command to Arnold, and now viewed him as a competitor for promotion and choice of assignments.[21]

It was not unusual in military establishments of the time that individuals passed over for promotion were expected to resign, so Arnold on March 12 wrote to Washington, offering his resignation, or alternatively asking for a court of inquiry. Washington refused his offer to resign, and wrote to members of Congress in an attempt to correct the situation, noting that "two or three other very good officers" might be lost if they persisted in making politically motivated promotions.[22] After Washington wrote Arnold explaining to him that the rejection was due to how the Congress had allocated promotions to the states (and Connecticut already had its quota of major generals), Arnold persisted in seeking some sort of inquiry, and complained in a letter to General Gates that "no gentleman who has any regard for his reputation will risk it with a body of men who seem to be governed by whim and caprice" and that he felt "the unmerited injury my countrymen have done me."[23]

John Adams was opposed to promotion of officers without Congressional approval, a stance that affected Arnold's promotion.

George Washington consistently supported Arnold

James Wilkinson was one of Gates' aides who spoke poorly of Arnold.

After plans were shelved to attack the British at Newport, Arnold left for Philadelphia to meet with the Continental Congress and Washington over his future. He stopped in New Haven to visit his family once again, and assisted his friend Colonel Lamb in hunting down Loyalists in the area.[23] A courier notified him on April 26 that a British force 2,000 strong under Major General William Tryon, the last British governor of New York, had landed at Fairfield, Connecticut. Tryon marched his force inland to Danbury, a major supply depot for the Continental Army. Driving away the few defenders, he ordered the destruction of the stores and a number of properties belonging to Patriot supporters.[24]

Arnold and Major General David Wooster, who had overall command of Connecticut's defense forces and was also in New Haven, hurriedly recruited about 100 volunteers locally. They then headed for Redding, the muster point specified by militia Major General Gold S. Silliman, who oversaw Fairfield County's defenses.[25] Silliman had mustered a force of 500 volunteers from eastern Connecticut.[26] Under Wooster's direction Arnold and his fellow officers moved their small force toward Danbury so they could intercept and harass the British as they returned to their ships. Wooster divided the force, with Arnold and Silliman leading 400 men to the village of Ridgefield, Connecticut to block the British march, while he led 200 men to harass the British rear guard. By 11 am on April 27 Wooster's column had caught up with and engaged Tryon's rear guard. In two brief skirmishes, Wooster was mortally wounded, but the action delayed the British long enough for Arnold and Silliman to establish a crude breastwork just north of Ridgefield.[27] In the ensuing battle, the militia companies put up stiff resistance before they were flanked and driven off.[26] Arnold's horse was shot, and when it went down, his leg was pinned under it. Arnold was very nearly bayoneted by a British soldier, but shot him with a pistol and managed to get away with a minor wound to his left leg.[28] The British camped for the night near Ridgefield, and then proceeded on toward the coast, harassed by militia all the way.[26] Arnold and Silliman rallied their troops, which grew to include Continental Army and artillery units as well as militia units from further afield. Arnold eventually established a fairly strong position on Campo Hill (in present-day Westport, Connecticut) near the beach where the British expected to embark.[29] The British managed to elude his attempt to entrap them, and drove off many of the militia with their field artillery before embarking on their ships and sailing back to New York. During the final skirmishing, Arnold had a second horse shot out under him.[30] When Congress learned of the action on May 2, it finally promoted Arnold to major general, although his seniority of rank was behind those promoted in February.[31]

After the Danbury raid, Arnold continued his journey to Philadelphia, stopping to meet with Washington at Morristown, New Jersey. During this time he learned of the publication of Brown's pamphlet, and insisted to Washington that his name had to be cleared. Arnold's lobbying paid off, and even opponents of the traditional promotion schemes, including John Adams, came to realize that Arnold was being unjustly treated.[32] After a lengthy hearing before the Board of War on May 21, in which Arnold's actions and financial accounts in the Quebec campaign were scrutinized, the board completely exonerated him, issuing a statement that it was satisfied with Arnold's "character and conduct, so cruelly and groundlessly aspersed in Brown's publication."[33] However, it took no steps to restore his seniority.[33]

The seniority issue had annoyed not just Arnold, but also John Stark, Nathanael Greene, John Sullivan, and Henry Knox. Stark resigned his commission as brigadier after Congress offered a major general's commission to a French soldier of fortune, Philippe de Coudray, and the other three complained loudly over the matter.[34][35] Congress passed over his petition for restoration of seniority, and deliberately snubbed him for consultation on the defense of Philadelphia in favor of Pennsylvania native Thomas Mifflin, one of the generals promoted ahead of him.[34] Arnold tendered his resignation to Congress on July 11.[35] However, Washington had written Congress the day before, informing them that a British army under General John Burgoyne had captured Fort Ticonderoga, and recommending in glowing terms that Arnold be sent north to assist in the defense of the Hudson River valley. Given Washington's strong support, Arnold asked that his resignation be shelved, and he left Philadelphia for the north.[36] In a vote on August 8, Congress voted against restoring Arnold's seniority. The next day, it offered a major general's commission to the Marquis de Lafayette, then just nineteen years old.[37]

In early August Schuyler dispatched Arnold and 900 men to relieve the garrison at Fort Stanwix on the upper Mohawk, which had been placed under siege by a British-Indian force led by Brigadier Barry St. Leger.[40] Arnold marched along the Mohawk to Fort Dayton, which he reached on August 20. There he attempted to recruit additional militia to enlarge the relief force, but was unsuccessful; the local militia had suffered grievously in the bloody Battle of Oriskany that ended the first attempt to relieve the siege.[41]

Uncomfortable with the number of troops available to him, Arnold opted for a deception to sow trouble in the besieger's camp outside Fort Stanwix. A number of Loyalists had been arrested near Fort Dayton, including one Hon-Yost Schuyler. Hon-Yost suffered from some form of mental illness which, while looked down on by the Europeans, was seen by many Indians as a touch of the Great Spirit. Arnold convinced Hon-Yost to spread rumors that large numbers of Americans, under the command of "The Dark Eagle", were about to descend on St. Leger's camp.[42] Hon-Yost's good conduct was assured by holding hostage his brother, who was also among the arrested.[43] Arnold's stratagem apparently worked. St. Leger recorded on August 21 that "Arnold was advancing, by rapid and forced marches, with 3,000 men", and the Indians of St. Leger's expedition, who made up the majority of his force, abandoned the siege the next day.[44] As a result, St. Leger lifted the siege and began the journey back to Montreal. Arnold did march to Stanwix, arriving after St. Leger had left; detachments sent by Arnold to chase after him spotted his boats on Lake Oneida.[45][46]

After leaving reinforcements with the Fort Stanwix garrison, Arnold returned to Stillwater, where General Gates had taken over the command from Schuyler. Arnold had learned of Gates' assumption of command while he was at Fort Dayton. He wrote a somewhat perfunctory congratulatory to Gates when he heard of the American victory in the Battle of Bennington, but a somewhat warmer letter he wrote to Schuyler at the same time somehow fell into Gates' hands. Gates provided a snub of sorts when he reported to Congress on the relief of Stanwix and the action at Bennington, and failed to mention Arnold's role; he did specifically mention Stark and Seth Warner, the principal commanders at Bennington, in his dispatch. Washington was more forthcoming with praise, recognizing that "the approach of General Arnold with his detachment" played a key role in the relief of Stanwix.[47]

On his return to Gates' camp, Arnold learned of the Congressional decision to not restore his seniority. He then annoyed Gates by taking on as aides several men who had been on Schuyler's staff, including Henry Brockholst Livingston. The two men also disagreed on strategy: Arnold argued in councils in favor of drawing Burgoyne into battle, while Gates preferred to establish a strong line of defense and wait for Burgoyne's assault.[48] Relations between the men deteriorated further when Gates effectively overrode brigade assignments he had asked Arnold to make, and were not helped by Gates' adjutant, James Wilkinson. Arnold characterized the scheming Wilkinson as a "designing villain"; Wilkinson is reported to have regularly cast aspersions on Arnold and his staff to Gates.[49]

This friction between the two men and their respective camps boiled over after the September 19 Battle of Freeman's Farm. In that battle, Arnold was forceful in wanting to move troops out of the strong American fortifications to head off a flanking maneuver. Gates grudgingly allowed this, and Arnold's troops sent out to counter the British advance precipitated the battle.[50] It has been widely recounted in histories of this battle that General Arnold was on the field, directing some of the action. However, John Luzader, a former park historian at the Saratoga National Historical Park, carefully documents the evolution of this story and believes it is without foundation in contemporary materials, and that Arnold remained at Gates' headquarters, receiving news and dispatching orders through messengers. Arnold biographer James Kirby Martin, however, disagrees with Luzader, arguing that Arnold played a more active role at Freeman's Farm by directing patriot troops into position and possibly leading some charges before being ordered back to headquarters by Gates.

The battle was technically a British victory, as they gained the field of battle. However, they suffered significant casualties that they could ill afford, the American army's strong position was not assaulted, and American casualties were comparatively modest.[51] According to Richard Varick, a former Schuyler aide and no friend of Gates, the general "seemed to be piqued" at the performance of Arnold's division in the battle, and Henry Brockholst Livingston wrote that Arnold was "the life and soul of the troops" and that he had "the confidence and affection of his officers and soldiers."[52] An officer unconnected to either camp commented that Arnold had "won the admiration of the whole army", and that the idea that Gates had squandered an opportunity to inflict a decisive blow on the British was widely held by officers.[52]

The Gates camp then engaged in a series of actions that Arnold perceived to be an attack. James Wilkinson wrote a letter to General Arthur St. Clair in Philadelphia in which he implied not only that Arnold was not involved in the battle, but that he was an impediment to Gates. Gates' official report to Congress notably made no mention of Arnold, Morgan, or other officers involved in leading the action, and specifically mentioned Arnold's nemesis John Brown, who had made an attack against Fort Ticonderoga the day before the battle.[53] A decision by Gates concerning Morgan's unit then caused relationships between Gates and Arnold to break down completely. Morgan's unit had technically been under Gates' command, but it had operated in the battle under Arnold's division and his direction. Gates formally realigned the units to reiterate that Morgan reported to him and not Arnold.[54] The ensuing discussion between Gates and Arnold on September 22 escalated into a shouting match, and ended with Gates relieving Arnold of his command. Arnold requested a pass to rejoin Washington's army, which he was given.[55] However, for unknown reasons, he decided to stay in camp. A common account of a memorial signed by Gates' field commanders encouraging him to stay has no basis in the documentary record;[56] it is known that Brigadier Enoch Poor, who had been critical of Arnold during the court martial at Ticonderoga, and other officers openly considered the idea.[57] This support for Arnold may have played a role in his announcement on September 26 that he was staying in camp even though his differences with Gates had not been resolved.[58]

When General Burgoyne made a reconnaissance in force of the American left on October 7, this began a series of actions that precipitated the Battle of Bemis Heights. According to conventional histories, Gates, now in command of the American left, ordered troops out to meet them.[59] At a critical point in the battle, Arnold, who may have been drinking, left his tent, mounted a horse, and rode off to the battlefield.[60] This chronology is based on reports of the action, most of which were recorded many years later, after Arnold's treason. A letter, brought to light in 2015 and written by an adjutant at Arnold's headquarters, tells a different story, indicating that Arnold requested and received permission from Gates to lead men out into the field.[61]

Rallying what had been his troops in the first battle, Arnold led them in a furious assault against two redoubts on the British right.[60] In this phase of the battle, one of the redoubts was taken, and Arnold's horse and leg were shot. When the horse went down, Arnold's leg was shattered in several places.[62] The battle was a resounding victory for the Americans. Burgoyne began a retreat, but was quickly surrounded by militia companies that streamed into the area, and surrendered on October 17.[63]

General John Burgoyne credited Arnold with the American victory.

Gates could not ignore Arnold's role in the second battle, since the news of Arnold's injuries traveled quickly. He limited acknowledgement of Arnold's participation to the leading of a "gallant" assault on the redoubt.[64] Much to Arnold's disgust, Gates himself was lauded by Congress and awarded a gold medal; Burgoyne, on the other hand, claimed that Arnold was responsible for his defeat.[64] Congress did finally vote to restore Arnold's seniority. However, Arnold 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.[65]

Arnold's contribution to the victory at Saratoga is commemorated by the Boot Monument in Saratoga National Historical Park. Donated by Civil War General John Watts de Peyster, it shows a boot with spurs and the stars of a major general. It stands at the spot where Arnold was shot on October 7 charging Breymann's redoubt, and is dedicated to "the most brilliant soldier of the Continental Army".[66]

The court martial to consider the charges against Arnold began meeting in December 1779. In spite of the fact that a number of members of the panel of judges were men ill-disposed to Arnold over actions and disputes earlier in the war, Arnold was cleared of all but two minor charges on January 26, 1780.[84] Arnold worked over the next few months to publicize this fact; however, in early April, just one week after Washington congratulated Arnold on the March 19 birth of his son, Edward Shippen Arnold, Washington published a formal rebuke of Arnold's behavior.[85]

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 his expenditures concluded that Arnold had failed to fully account for his expenditures incurred during the Quebec invasion. It concluded that he owed the Congress some £1,000, largely because he was unable to document his expenses. A significant number of the necessary documents were lost during the retreat from Quebec; once again frustrated by Congress, Arnold resigned his military command of Philadelphia in late April.[87]
