The first submarine I know of was made by Drebbel in 1620. Apparently it was demonstrated before King James 1st traveling up and down the Thames several times. The first military use of a submersible vehicle was by David Bushells 'Turtle' in 1776 when it attacked, unsuccessfully HMS Eagle. I also read somewhere that the French built a submarine called 'Nautilus' during the Napoleonic Wars.Originally Posted by asj_india
Richard Gatling took out his patent on the Gatling Gun in 1862. His machine utilises breach loading, percussion caps and a firing pin system, all more advanced than the flintlock muzzle loading weapons available in the 1820's.
