Benedict Arnold in the context of "Treason laws in the United States"

The Green Mountain Boys were a militia organization established in 1770 in the territory between the British provinces of New York and New Hampshire, known as the New Hampshire Grants and later in 1777 as the Vermont Republic (which later became the state of Vermont). Headed by Ethan Allen and members of his extended family, it was instrumental in resisting New York's attempts to control the territory, over which it had won de jure control in a territorial dispute with New Hampshire.

Some companies served in the American Revolutionary War, including notably when the Green Mountain Boys, led under the command of Ethan Allen while being assisted by Benedict Arnold, captured Fort Ticonderoga on Lake Champlain on May 10, 1775, and invaded Canada later in 1775. In early June 1775, Ethan Allen and his then subordinate, Seth Warner, induced the Continental Congress at Philadelphia to create a Continental Army ranger regiment from the then New Hampshire Grants. Having no treasury, the Congress directed that New York's revolutionary Congress pay for the newly authorized regiment. In July 1775, Allen's militia was granted support from the New York revolutionary Congress.

West Point is a census-designated place in Orange County, New York, United States. It is the oldest continuously occupied military post in the United States.

Located on the Hudson River in New York, General George Washington stationed his headquarters in West Point in the summer and fall of 1779 during the American Revolutionary War, and later called it "the most important Post in America" in 1781 following the war's end. West Point was also the site of General Benedict Arnold's failed attempt at treason during the Revolutionary War.

The invasion of Quebec (June 1775 – October 1776, French: Invasion du Québec) was the first major military initiative by the newly formed Continental Army during the American Revolutionary War. The objective of the campaign was to seize the Province of Quebec (part of modern-day Canada) from Great Britain, and persuade French-speaking Canadiens to join the revolution on the side of the Thirteen Colonies. One expedition left Fort Ticonderoga under Richard Montgomery, besieged and captured Fort Saint-Jean, and very nearly captured British General Guy Carleton when taking Montreal. The other expedition, under Benedict Arnold, left Cambridge, Massachusetts, and traveled with great difficulty through the wilderness of Maine to Quebec City. The two forces joined there, but were defeated at the Battle of Quebec in December 1775.

Montgomery's expedition set out from Fort Ticonderoga in late August, and in mid-September began besieging Fort St. Johns, the main defensive point south of Montreal. After the fort was captured in November, Carleton abandoned Montreal, fleeing to Quebec City. Montgomery took control of Montreal before heading for Quebec, his army much-reduced by expiring enlistments. There he joined Arnold, who had left Cambridge in early September on an arduous trek through the wilderness that left his surviving troops starving and lacking supplies and equipment.

The capture of Fort Ticonderoga occurred during the American Revolutionary War on May 10, 1775, when a small force of Green Mountain Boys led by Ethan Allen and Colonel Benedict Arnold surprised and captured the fort's small British garrison. The cannons and other armaments at Fort Ticonderoga were later transported to Boston by Colonel Henry Knox in the noble train of artillery and used to fortify Dorchester Heights and break the standoff at the siege of Boston.

Capture of the fort marked the beginning of offensive action taken by the Americans against the British. After seizing Ticonderoga, a small detachment captured the nearby Fort Crown Point on May 11. Seven days later, Arnold and 50 men raided Fort Saint-Jean on the Richelieu River in southern Quebec, seizing military supplies, cannons, and the largest military vessel on Lake Champlain.

The Battles of Saratoga were fought September 19 and October 7, 1777 over the same ground by the American Continental Army and the British Army near Saratoga, New York during the American Revolutionary War. The second battle ended with a decisive American victory, and the surrender of the British army there. The outcome greatly affected the course of the war, persuading France to enter the war as an American ally. In both battles, General John Burgoyne commanded the British forces, while General Horatio Gates oversaw the American force. Historian Edmund Morgan described Saratoga as "a great turning point of the war", because it won for Americans the foreign assistance from France, which was the last element needed for victory."

The British Army's campaign in New York was aimed at dividing New England from the middle and southern colonies. Burgoyne led an invasion army of 7,200 to 8,000 men southward from Canada through the Champlain Valley. Hoping to meet British forces marching northward from New York City and eastward from Lake Ontario, Burgoyne's goal was to take Albany, New York. The strategy began promisingly, but stalled due to logistical issues. British General William Howe never moved his forces north, and Brigadier General Barry St. Leger turned back his forces meant to arrive from the west, leaving Burgoyne surrounded by the Americans in upstate New York, 15 miles (24 km) short of his goal. Burgoyne fought two battles, which took place 18 days apart, on the same ground 9 miles (14 km) south of Saratoga, New York. In the first battle, at Freeman's Farm on September 19, Burgoyne won a tactical victory over the Continental Army at the cost of heavy casualties. The battle began with Burgoyne's attempt to flank the entrenched American position on Bemis Heights with some of his troops. American Major General Benedict Arnold anticipated the maneuver and placed significant forces in his way. Still, Burgoyne was able to gain the field. Skirmishes continued in the following days while Burgoyne waited in the hope that reinforcements would arrive from New York City.

The Battle of Quebec (French: Bataille de Québec) was fought on December 31, 1775, between American Continental Army forces and the British defenders of Quebec City as part of the invasion of Quebec of the American Revolutionary War. The battle was the first major defeat of the war for the Americans, and it came with heavy losses. General Richard Montgomery was killed, Benedict Arnold was wounded, and Daniel Morgan and more than 400 men were taken prisoner. The city's garrison, a motley assortment of regular troops and militia led by Quebec's provincial governor, General Guy Carleton, suffered a small number of casualties.

Montgomery's army had captured Montreal on November 13, and early in December they became one force that was led by Arnold, whose men had made an arduous trek through the wilderness of northern New England. Governor Carleton had escaped from Montreal to Quebec, the Americans' next objective, and last-minute reinforcements arrived to bolster the city's limited defenses before the attacking force's arrival. Concerned that expiring enlistments would reduce his force, Montgomery made the end-of-year attack in a blinding snowstorm to conceal his army's movements. The plan was for separate forces led by Montgomery and Arnold to converge in the lower city before scaling the walls protecting the upper city. Montgomery's force turned back after he was killed by cannon fire early in the battle, but Arnold's force penetrated further into the lower city. Arnold was injured early in the attack, and Morgan led the assault in his place before he became trapped in the lower city and was forced to surrender. Arnold and the Americans maintained an ineffectual blockade of the city until spring, when British reinforcements arrived.
