Referring to the failure of Fulton to induce the various Powers to adopt his submarine boat and torpedo, Admiral Porter said (in 1878) that naval men seventy years ago, whether in this country or abroad, saw no prospect in the success of Fulton’s scheme but the destruction of the service which was then their pride and glory, and it was hardly to be wondered at that all plans to destroy ships by other means than the legitimate eighteen-pounder were looked upon with disfavour. So the torpedo slept, but in time it reappeared invested with such deadly attributes that no nation could afford to disregard its claims as the most destructive implement of naval warfare yet devised. During the “Second War of Independence” (1812–1814) some unsuccessful attacks were made by a diving vessel on British men-of-war, and this is generally understood to be one of Fulton’s vessels. The following extract is from a work published by James Kelly in 1818. “About this time—that is the summer of 1813—some infamous and insidious attempts were publicly encouraged for the destruction of the British men-of-war upon the coasts of America by torpedoes and other explosive machinery, as will appear from the following extract from the American newspapers. “‘A gentleman at Norwich, U.S., has invented a diving boat, which by means of paddles he can propel under water at the rate of three miles an hour, and ascend and descend at pleasure. He has been three times under the bottom of the _Ramilies_ off New London. In the first attempt, after remaining under some time, he came to the top of the water like the porpoise for air, and as luck would have it, came up but a few feet from the stern of the _Ramilies_. “‘He was observed by a sentinel on deck who sang out “Boat ahoy!” immediately on hearing which, the boat descended without making a reply. Seeing this an alarm gun was fired on board the ship and all hands called to quarter, the cable cut and the ship got under weigh with all possible despatch, expecting to be blown up by a torpedo. “‘In the third attempt he came up directly under the _Ramilies_, and fastened himself and his boat to her keel, where he remained half an hour and succeeded in perforating a hole through her upper, but while engaged in screwing a torpedo to her bottom the screw broke and defeated his object for that time. So great is the alarm and fear on board the _Ramilies_ of some such stratagem being played upon them, that Commodore Hardy has withdrawn his force from before New London and keeps his ship under weigh all the time instead of lying at anchor as formerly.’”
