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 in the Raid of Richmond and nearby areas, 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.
