No, Benedict Arnold was not hanged. In fact, Arnold lived to a relatively old age after his infamous betrayal during the American Revolutionary War.
Arnold was a general in the Continental Army who famously defected to the British side in 1780. His actions were seen as treasonous, and he became synonymous with betrayal in American history. After switching allegiances, Arnold was given a command in the British Army, where he continued to serve until the end of the war.
After the war, Arnold moved to Britain, where he lived out the remainder of his life. He died in 1801 in London at the age of 60. Although many sought justice for his betrayal, he never faced trial or execution. Arnold’s legacy remains controversial, but his life ended without the punishment that many may have expected after his actions during the war.
