Overview
Benedict Arnold (June 14, 1801) was an American-born military officer who served during the American Revolutionary War. He fought with distinction for the American Continental Army and rose to the rank of major general before defecting to the British in 1780. General George Washington had given him his fullest trust and had placed him in command of West Point in New York. Arnold was planning to surrender the fort to British forces, but the plot was discovered in September 1780, whereupon he fled to the British lines. In the later part of the war, Arnold was commissioned as a brigadier general in the British Army and placed in command of the American Legion. He led the British army in battle against the soldiers whom he had once commanded, after which his name became synonymous with treason and betrayal in the United States.
Arnold was born in Connecticut. He was a merchant operating ships in the Atlantic when the war began. He joined the growing American army outside of Boston and distinguished himself by acts that demonstrated intelligence and bravery: In 1775, he captured Fort Ticonderoga. In 1776, he deployed defensive and delay tactics at the Battle of Valcour Island in Lake Champlain that gave American forces time to prepare New York's defenses. His performance in the Battle of Ridgefield in Connecticut prompted his promotion to major general. He performed operations that provided the Americans with relief during the siege of Fort Stanwix, and key actions during the pivotal 1777 Battles of Saratoga in which he sustained leg injuries that put him out of combat for several years.
Arnold repeatedly claimed that he was being passed over for promotion by the Continental Congress, and that other officers were being given credit for some of his accomplishments. Some in his military and political circles charged him with corruption and other bad acts. After formal inquiries, he was usually acquitted, but Congress investigated his finances and determined that he was indebted to Congress and that he had borrowed money heavily to maintain a lavish lifestyle.
Arnold mingled with Loyalist sympathizers in Philadelphia and married into the Loyalist family of 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.
