After the country resumed unrestricted submarine warfare once more, Wilson cut diplomatic ties. While the American public and leadership were not ready for war, the path to an eventual declaration of war had been set as a result of the sinking of Lusitania. The Mediterranean was an attractive theater of operations to the German Naval Command; a significant proportion of British imports passed through it, it was critical to French and Italian trade, and submarines would be able to operate effectively in it even in autumn and winter when poor weather hampered Atlantic and North Sea operations. Though tactically a draw, the battle did allow the British to maintain superiority in the Northern Atlantic and to continue their crippling blockade of Germany, in which the U.S. Navy later helped following entry into war.

Defensive measures, such as arming merchant ships, and advising them to either run, or turn towards the U-boat in order to ram, or force it to submerge, were the most effective. One of U-9's engines broke down and she had to return to Heligoland. Convoying imposed severe delays on shipping, and was believed to be counterproductive, amounting to a loss of carrying capacity greater than the loss inflicted by the U-Boats. When did ww1 start and end? 24 This figure is roughly 70% of all allied shipping losses in all theatres of the war and to all hostile action. Faced with a German fleet that turned away, he would assume a submarine trap, and decline to follow, but would move at high speed to the flank, before deploying or opening fire; the aim of this would be to fight the battle away from the ground chosen by his enemy, and forcing any U-boats present to surface if they intended to follow.[23]. When coupled with Germany's policy of unrestricted submarine warfare, the result was that Brazilian ships were soon lost, which drove the country closer to declaring war on the Central Powers.

The German Chancellor, Theobald von Bethmann Hollweg, felt that such a submarine blockade, based on "shoot without warning", would antagonise the United States and other neutrals. Holtzendorff proposed breaking Britain's back by sinking 600,000 tons of shipping per month, based on a February 1916 study by Dr. 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. American submarine chasers also engaged in one battle against Austro-Hungarian forces during the war. . DIVE!

It was a foggy morning as Captain William Turner navigated the RMS Lusitania through the final and most precarious leg of its voyage from New York City to Liverpool, England. [45], The logical response to the convoy system, which concentrated forces for the defence, was to similarly concentrate the attacking force. The total in December fell to 17 ships (73,741 tons) which was still over half the total tonnage sunk in all theaters of operation at the time. However monthly shipping losses had dropped to around 300,000 GRT, and never rose to the levels suffered in spring 1917. Germany could not possibly deal with British naval strength on an even basis, and the only possible way Germany could impose a blockade on Britain was through the U-boat. However, US President Woodrow Wilson refused to overreact, though some believed the massive loss of life caused by the sinking of Lusitania required a firm response from the US. During World War I, Germanys unprecedented use of Untersee-boots (U-boatsfor short) significantly changed the face of the conflict. Additionally, there were certain choke points through which shipping had to pass, such as the Suez Canal, Malta, Crete, and Gibraltar. Several U-boats with the German Imperial Navy are still considered missing today.

An American auxiliary cruiser heavily damaged a U-boat during the action of 4 April 1918. They were also assembling three Type UC I minelaying submarines, which were ordered converted into transports to carry small quantities of critical supplies to Turkey.
