Though knowing the French had no further interest, the British wished to ensure a man of Fulton's talents were on their side; offering him £800 to come to England (his original planned destination before going to France) and develop a second "Nautilus" for them. The victory at Trafalgar made his work unnecessary, and he was increasingly sidelined until he left, in frustration, for America in October 1806. He left his papers on submarines with the American consul in London. He never asked for them, never referred to his "Nautilus" work, and the papers went unpublished until 1920.
