Question: Who was hung for assisting the attempted surrender of a defector from the American Continental Army to the British Army?

Context:
Benjamin Lincoln
Benjamin Lincoln (January 24, 1733 (O.S. January 13, 1732) – May 9, 1810) was an American army officer.
 He served as a major general in the Continental Army during the American Revolutionary War.
 Lincoln is notable for being involved in three major surrenders during the war: his participation in the Battles of Saratoga (sustaining a wound shortly afterward) contributed to John Burgoyne's surrender of a British army, he oversaw the largest American surrender of the war at the 1780 Siege of Charleston, and, as George Washington's second in command, he formally accepted the British surrender at Yorktown.
1st Virginia State Regiment
The 1st Virginia State Regiment was a regiment of Virginia Militia that fought during the American Revolutionary War.
 The regiment was authorized by the General Assembly of the Commonwealth of Virginia in December 1776 as a force of regular troops for the Commonwealth's defense.
 In 1777, Virginia had difficulty meeting its quota for the regular line of the Continental Army.
 As a result, in July 1777 under the command of Colonel George Gibson, the regiment began a march North to temporarily join the Continental Army in the Philadelphia Campaign.
 In January 1778, the Virginia General Assembly passed an act directing that the 1st Virginia State Regiment "now in Continental service, be continued in said service instead of the Ninth Virginia Regiment, made prisoners by the enemy in the Battle of Germantown."
 The regiment camped at Valley Forge in the winter of 1777-78 and at Middlebrook in the winter of 1778-79 and participated in the Battle of Monmouth.
 The regiment remained in the service of the Continental Army until late 1779 when redeployed Virginia.
 Unlike the standard division of eight found in the regular line regiments of the Continental Army, the 1st Virginia State Regiment consisted of ten companies including one of light infantry.
Siege of Yorktown
The Siege of Yorktown, also known as the Battle of Yorktown, the Surrender at Yorktown, German Battle or the Siege of Little York, ending on October 19, 1781, at Yorktown, Virginia, was a decisive victory by a combined force of American Continental Army troops led by General George Washington and French Army troops led by the Comte de Rochambeau over a British Army commanded by British peer and Lieutenant General Charles Cornwallis.
 The culmination of the Yorktown campaign, the siege proved to be the last major land battle of the American Revolutionary War in the North American theater, as the surrender by Cornwallis, and the capture of both him and his army, prompted the British government to negotiate an end to the conflict.
 The battle boosted faltering American morale and revived French enthusiasm for the war, as well as undermining popular support for the conflict in Great Britain.
Benedict Arnold
Benedict Arnold (January 14, 1741 [O.S. January 3, 1740] June 14, 1801) was a general during the American Revolutionary War, who fought for the American Continental Army, and later defected to the British Army.
 While a general on the American side, he obtained command of the fortifications at West Point, New York (which after 1802 would become the site of the U.S. Military Academy), overlooking the cliffs at the Hudson River (upriver from British-occupied New York City), and planned to surrender them to British forces.
 This plan was exposed in September 1780.
 He was commissioned into the British Army as a brigadier general.
Battle of Germantown
The Battle of Germantown was a major engagement in the Philadelphia campaign of the American Revolutionary War.
 It was fought on October 4, 1777, at Germantown, Pennsylvania, between the British Army led by Sir William Howe, and the American Continental Army, with the 2nd Canadian Regiment, under George Washington.
Board of War
The Board of War, also known as the Board of War and Ordnance, was created by the Second Continental Congress as a special standing committee to oversee the American Continental Army's administration and to make recommendations regarding the army to Congress.
 On January 24, 1776, Congressional delegate Edward Rutledge, echoing Gen. George Washington's own concerns, suggested that a war office similar to Britain's be established.
 Pressure from Washington and the large volume of military business led Congress to establish the Board of War and Ordnance on June 12, 1776.
 Five delegates of Congress, initially John Adams, Roger Sherman, Benjamin Harrison, James Wilson, and Edward Rutledge, assisted by a permanent secretary, Richard Peters, composed the Board of War.
 They assumed the prescribed responsibilities for compiling a master roster of all Continental Army officers; monitoring returns of all troops, arms, and equipment; maintaining correspondence files; and securing prisoners of war.
 The Board of War began functioning on June 21, 1776.
John André
John André (2 May 1750 – 2 October 1780) was a British Army officer hanged as a spy by the Continental Army during the American Revolutionary War for assisting Benedict Arnold's attempted surrender of the fort at West Point, New York to the British.
National Memorial Arch
The United States National Memorial Arch, located in Valley Forge National Historical Park, Chester County, Pennsylvania, is a monument built to celebrate the arrival of General George Washington and the Continental Army at Valley Forge.
 Valley Forge was the military camp 18 miles northwest of Philadelphia where the American Continental Army spent the winter of 1777–78 during the American Revolutionary War.
 Starvation, disease, malnutrition, and exposure killed more than 2,500 American soldiers by the end of February 1778.
List of Continental Army units
The Continental Army was the national army of first the Thirteen Colonies, and then the independent United States, during the American Revolutionary War, established by a resolution of the Congress on June 14, 1775, three days before the Battle of Bunker Hill, where it saw its first action under that title.
.
 The Continental Congress took a number of steps in the spring of 1775 to create the army in response to the Battles of Lexington and Concord in April and the seizure of Fort Ticonderoga in May.
 The units composing the Continental Army changed frequently, especially in the first two years of the war.
 From 1777 to the close of the war, the organization of the Continental Army became progressively more systematic and sophisticated.
 The Continental Army that served at Yorktown in 1781 bore very little resemblance to the Continental Army that blockaded Boston in 1775.
Pulaski's Legion
Pulaski's Legion was raised on March 28, 1778 at Baltimore, Maryland under the command of Kazimierz Pułaski for service with the Continental Army during the American Revolutionary War.
 The Legion consisted of one troop of lancers, two troops of dragoons and 200 light infantry soldiers.
 It was one of the few cavalry regiments in the American Continental Army.
