The first confirmed U-boat to be sunk by a depth charge was the UC, which had sunk four Allied ships in the English Channel.
A further series of operations, in August and Octoberwere similarly unfruitful, and the strategy was abandoned in favor of resuming commerce warfare.
The German military staffs urged the Kaiser to authorize unrestricted submarine warfare in all oceans and seas. She made a second equally successful voyage in autumn of that year.
Skippers were to conduct only restricted submarine warfare by prize rules in waters of the British Isles, where there were numerous American and other neutral ships, but they were permitted to wage unrestricted submarine warfare in the Mediterranean.
The initial forays were remarkable. The German submarine force had grown to substantial size by September The decision to do so in February was largely responsible for the entry of the United States into the war. If sea water got into the battery cells, poisonous chlorine gas was generated.
But the plan went awry. Early in the war both Germany and Great Britain deployed submarines on offensive missions. The Central Powers, composed of Germany and the Austro-Hungarian Empire, had planned to defeat France in a quick campaign, then turn about and crush czarist Russia.
Also, the two UE1-class minelaying boats laid minefields in the White Sea. At his request, on April 6 the Congress declared war on the Central Powers. German submarine losses were between 5 and 10 each month, and they soon realized the need to increase production, even at the expense of building surface warships.
Neither the Kaiser nor his Chancellor was keen on the proposal. Richard Fuss, who had postulated that if merchant shipping was sunk at such a rate, Britain would run out of shipping and be forced to sue for peace within six months, well before the Americans could act.
Just two U-boats were sunk by these measures in Two days later, the House of Representatives endorsed the declaration by a vote of to 50 and America formally entered World War I. Reflecting the growing anger and outrage in America, President Wilson reacted firmly and militantly to this all-out U-boat campaign.
The ships hit graphs above include all types of ships — large and small. After the U-boats lost 41 of their number during that month, they withdrew temporarily from the Atlantic.
World War One was one of the bloodiest conflicts in history. No cargo ships or tankers except those unmistakably armed could be attacked outside the war zone.
By that time, too, there was no shortage of German submarine torpedoes; U-boat skippers did not have to rely so heavily on deck guns.But the U-boats of WWI were very comparable in size, speed, range, and armament to their later cousins.
Regardless of the various measures of success, I think that the U-boat campaigns during the First World War are an undervalued area for research and writing. For British merchant vessels operating during World War I, few things were so terrifying as the submarine.
The German navy used the Unterseeboot, or U-boat, to sink 5, ships measuring more than 13 million gross register tons during the war. The typical U-boat was feet long, carried 35 men and 12 torpedoes, and could travel underwater for two hours at a time.
In the first few years of World War I, the U-boats took a terrible toll on Allied shipping. AP By Aric Jenkins September 19, A World War I-era German submarine (commonly referred to as a U-boat) filled with 23 bodies was discovered in the waters off the coast of Belgium, officials.
The U-boat Campaign from to was the World War I naval campaign fought by German U-boats against the trade routes of the Allies. It took place largely in the seas around the British Isles and in the Mediterranean. The German Empire relied on imports for food and domestic food production.
