B. 1741 Benedict Arnold was a General in the American Revolution, and America's best-known traitor, though I'm not sure that's what he would have had printed on his business cards. Arnold also happens to be a war hero on the American side, though many people don't know that. Before Arnold turned traitor, he had a reputation both for bravery and for genuinely caring for the soldiers who served under him. He was instrumental to the rebel capture of Fort Ticonderoga in May of 1775, and his leg was crippled during the Battle of Saratoga in 1777. So he certainly put the effort in.
