Warsop drew attention to the fact that in 1862 his torpedo based on "precisely the same principle as Mr. Whitehead's" was given a days trial at Portsmouth during which a series of mishaps occurred in his two attempts to launch the torpedo, so at the end of the day no assistance or encouragement was given to him by the authorities, they later stated that "they have no desire to make any further trial of the torpedo." He went on further to say "It will thus be patent that our Government are paying a large sum of money for an invention which, I believe, has no claim to novelty and can be used by any other nation if considered of sufficient value."
