What type of experiments with mines did Samuel Colt deal with?

Answer 1

Samuel Colt was one of the better known weapons experts in the 1840's in America. He conducted experiments with underwater mine explosives. His underwater weapons were detonated by electrical impulses sent from shore with an insulated cable. On at least five separate tests he was able to destroy vessels he used for experiments. In one test he was able to destroy a "test" vessel of five hundred tons. Later on he was able to detonate mines via cable from as faraway as forty miles. He ended his experiments by the mid 1840's.
