The first underwater warship was developed by Leonardo da Vinci. da Vinci kept his plans secret because he didn't want to make war any more terrifying than it already was. In 1578 William Borne began drawing plans for a submarine. His submarine was never built. Borne's submarine worked by using extra tanks which could be filled so the submarine would submerge. The tanks would be emptied for the submarine to surface. In 1620 Cornelis Drebbel, a Dutch inventor, built a leather covered rowboat with oars. The oars came out through watertight seals. Twelve people could ride in the submarine. Drebbel was an engineer who worked for the British navy. Drebbel was the first to discuss the problem of air replenishment while the submarine submerged. Drebbel's submarine could only go down about fifteen feet. It could stay underwater for a couple of hours.
Cyrus Field led the establishment of the first transatlantic telegraph cable. The first transatlantic message was received in 1858, but the cable stopped working after about 3 weeks. This cable was replaced by a new cable that was successfully laid in 1866 after five earlier attempts dating back to 1857.
