German submarine losses were between 5 and 10 each month, and they soon realised the need to increase production, even at the expense of building surface warships. British submarines were the busiest with 13 kills. All of the sunken U-boats are relatively close to the coast, at depths of no more than 15 meters (about 50 feet). By the end of World War I, 344 U-boats had been commissioned, sinking more than 5,000 ships and resulting in the loss of 15,000 lives.

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]. The German Navy sent their first submarines to the Mediterranean in response to the Anglo-French Dardanelles campaign, after it became obvious that their Austro-Hungarian allies could do little against it with their small submarine force, which nevertheless was successful in defending the Adriatic.

The disaster immediately strained relations between Germany and the neutral United States, fueled anti-German sentiment and set off a chain of events that eventually led to the United States entering World War I. Lusitania, owned by the Cunard Shipping Line, was launched in 1906 to carry passengers on transatlantic voyages. The Allies insisted that an essential precondition of any armistice was that Germany surrender all her submarines, and on 24 October 1918 all German U-boats were ordered to cease offensive operations and return to their home ports. As historian Erik Larson writes inDead Wake, Turners New York managers at Cunard, the company that owned the boat, even issued an official statement reassuring the public. Allied countermeasures were largely ineffective; the complex arrangements for co-operation between the various navies meant a fragmented and unco-ordinated response, while the main remedy favored by the Allies for the U-boat menace, the Otranto Barrage, was of little value. Attacking without warning, German U-Boats sank nearly 100,000GRT per month, an average of 1.9 ships daily. These boats sank 34 ships (19 of them Norwegian) before winter ice closed the area for operations.

The European naval powerbegan operating U-boats in 1914, as an alternative to standard warships, which carried the not-insignificant downside of being visible to enemyvessels. These came too late to see action, however, and no successes were recorded by them. During the Great War United States Navy warships were deployed to both the Atlantic and Mediterranean with the primary objective of fighting German submarines and escorting convoys. 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. In an attempt to justify the devastating attack, Germany later cited the 173 tons of war munitions the ship had also been carrying. 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. (2) Neutral vessels also will run a risk in the War Zone, because in view of the hazards of sea warfare and the British authorization of January 31 of the misuse of neutral flags, it may not always be possible to prevent attacks on enemy ships from harming neutral ships.

Since these were too large to be shipped in sections by rail to Pola like the Type UB I, the materials for their construction and German workers to assemble them were sent instead. The destruction of enemy shipping by German U-boats was a spectacular feature of both World Wars I and II. But President Wilson still wasnt ready to take his country to war. Attempts were also made to close routes like the Straits of Dover with boom nets and minefields, the so-called Dover Barrage; to lay minefields around U-boat bases, and station submarines on patrol to catch them leaving or entering port. The North Sea Mine Barrage saw the laying of over 70,000 mines during the summer of 1918. She has previously written for The Boston Globe, PolicyMic and Interview Magazine. A few of the U-cruisers also made long voyages south to the Azores and the African coast, where they operated generally unmolested against shipping operating in the area, though one, U-154, was torpedoed by the British submarine HMSE35 off the coast of Portugal in May 1918. Seven Type U-151 and three Type U-139 had been built, the Type U-151 originally as large merchant U-boats for shipping material to and from locations otherwise denied German surface ships, such as the United States, and 6 Type U-151 were refitted for war duty in 1917.

[39], On 27 January, Admiral Beatty observed that "The real crux lies in whether we blockade the enemy to his knees, or whether he does the same to us. But it was completely unclear what had happened, for example, to UB 17, under the command of naval Lieutenant Albert Branscheid, with its crew of 21 men, or where the 27-member crew of UC 21, used as a minelayer and commanded by naval Lieutenant Werner von Zerboni di Sposetti, had perished.

American citizens were saddened and stunned but not ready to rush to war. It is hard to determine how almost a century of lying in place, as well as sedimentary deposits, have changed the structural integrity of the wrecks.
