The German government maintained the British naval blockade was illegal under international law. The German high command realized the resumption of unrestricted submarine warfare meant war with the United States but calculated that American mobilization would be too slow to stop a German victory on the Western Front and played a large role in the United States entering the war in April 1917.Īll participants were supposed to abide by the Hague Conventions of 18, but this was found to be impracticable for submarines. Admiral Henning von Holtzendorff (1853–1919), chief of the admiralty staff, argued successfully in January 1917 to resume the attacks and thus starve the British. German submarine attacks on Allied merchant ships, especially the sinking of Lusitania, turned American public opinion against the Central Powers. Only a few actions occurred outside the wider European-Atlantic theatre. British and Allied submarines conducted widespread operations in the Baltic, North, Mediterranean and Black Seas along with the Atlantic Ocean. Submarine warfare in World War I was primarily a fight between German and Austro-Hungarian U-boats and supply convoys bound for the United Kingdom, France, and Russia.

But who notices that in the full flush of either battle - or invention? The South scored one victory and paid a kamikaze price in human life. So the Civil War was the great proving ground for modern submarines. They also bought a French submarine, the Alligator. Perhaps that was a tribute to the Whale's intelligence. They called it the Intelligent Whale, but they didn't use it in combat. That was the first time a sub destroyed an enemy ship. But it never came back to the surface from that Pyhrric victory. Finally, in 1864, the Hunley sank the ironclad Union sloop Housatonic. The South hurled it into battle over and over. The Hunley's weapon was also a spar torpedo. It also warned the crew by flickering out when too little oxygen was left. An eight-man crew turned a hand-cranked propeller in that terrible small space. It was made from a steam boiler forty feet long and less than four feet in diameter. The first real submarine was the Confederate Hunley.
The South built twenty more Davids, and some of them damaged Union boats. But the hole was above the waterline and the ship survived. The David attacked a Union ironclad and managed to blow a hole in its side. The trick was to ram it into the enemy and hope you suffered less damage than he did. A long underwater pole held an explosive charge out in front. So her smokestack and breathing tube protruded above the surface.ĭavid's claim to the title submarine is flimsy, but her offensive weapon was a spar torpedo. The steam-driven David couldn't burn fuel to make steam if it was fully submerged. Civil War ironclads had lowered themselves further and further down into the protective water. David wasn't a pure submarine, but it came close. They launched a boat called the David in 1862 and sent it at the Union Goliaths. Years later, he made a submarine for the French and tried without success to sink the enemy with it.ĭuring the Civil War, the Confederacy made a far more serious, far more desperate, try at submarine warfare. One person who got the point was Robert Fulton. His one-man, hand-cranked machine did little harm to the English in 1776, but it made the point.
