At the start of hostilities, the Austro-Hungarian Navy had seven U-boats in commission; five operational, two training; all were of the coastal type, with limited range and endurance, suitable for operation in the Adriatic. When Germany began its U-boat campaign against Britain, Wilson had warned that the US would hold the German government strictly accountable for any violations of American rights.

As of April 1915, German forces had sunk 39 ships and lost only three U-boats in the process. The first U-boats sent, U-21 and the two small coastal boats, UB-7 and UB-8, achieved initial success, U-21 sinking the Royal Navy pre-dreadnought battleships HMSTriumph and HMSMajestic on 25 and 27 May, respectively, on her way to Constantinople, but ran into severe limitations in the Dardanelles, where swarms of small craft and extensive anti-submarine netting and booms restricted their movements. By law, the sites are considered inviolable gravesites. On 2 June 1918, known to some historians as "Black Sunday", U-151 sank six US ships and damaged two others off the coast of New Jersey in the space of a few hours. The seasoned 58-year-old captain believed in the abilities of the Lusitania to outrun any submarine, technology that was still considered relatively primitive at the time. The Japanese ships were very effective in patrol and anti-submarine activity. 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. By the end of World War I, German submarines known as U-boats had managed to sink 10 vessels off North Carolina alone, and 200 American shipsin total. On February 18, 1915, Germany offered fair notice to its rivals by declaring unrestricted submarine warfare in the waters surrounding the British Isles.

Nevertheless, the archeologists don't want to miss the opportunity to try to recover other signs of the erstwhile sailors in the underwater crypts. 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. Dunkley is an underwater archeologist who dives for lost treasures. 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. In August 1915, a German submarine sunk the British ocean liner S.S. Arabic and claimed self-defense. It was disliked by both merchant and naval captains, and derided as a defensive measure. [5] Their aim was to sink capital ships of the British Grand Fleet, and so to reduce the Grand Fleet's numerical superiority over the German High Seas Fleet. It appeared to be cobbled together with .

Germans lost many U-boats to the Allied submarine forces during 1939-1945. "We owe it to these people to tell their story," says Dunkley. By 1918 the Allied anti-submarine measures had continued to become more effective. On 21 December 1917 the British government requested that a Brazilian naval force of light cruisers be placed under Royal Navy control and a squadron comprising the cruisers Rio Grande do Sul and Bahia, the destroyers Paraba, Rio Grande do Norte, Piau, and Santa Catarina, and the support ship Belmonte and the ocean-going tug Laurindo Pitta was formed, designated the Diviso Naval em Operaes de Guerra ("Naval Division in War Operations").

The new policy of unrestricted submarine warfare was initially a success. FACT CHECK: We strive for accuracy and fairness. 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.

In an attempt to justify the devastating attack, Germany later cited the 173 tons of war munitions the ship had also been carrying. Venturing inside would definitely be extremely dangerous," Dunkley says. Other successes followed. Further mines were laid off the southeast coast by UC-1, UC-3, UC-6, and UC-7. But after a German U-boat sank three English armored cruisers, an unbridled enthusiasm erupted in the German Empire for this still relatively untested form of naval warfare. By spring of the next year, Germany had roughly 35 functioning U-boats, many of which utilized torpedoes and had been highly effective in targeting ships passing through their vicinity.

Now they are in a race against time to learn the secrets hidden in their watery graves. But the strategy was difficult to implement because it was very difficult to coordinate such complex maneuvers at the time. On 19 August 1915, U-24 sank the White Star liner SSArabic, outward bound for America, 50mi (80km) south of Kinsale. He was dismayed to be informed by the Admiralty that Germany would win the war if its submarines went unchecked, and cabled Washington to have USN destroyers despatched to Queenstown, Ireland, from where they were to patrol to the west.

Eventually, a shell from the merchant's gun fell 50 meters away from the submarine, prompting the U-boat to submerge and retreat.[41]. [51], By the end of 1918, Allied shipping losses were 2 million GRT for the year overall (averaging 323,000 tons through March and declining thereafter) at a cost of 69 submarines, the U-boat Arm's worst year.[44]. The British could see it as a peculiar irony of history that these measures are now benefiting the heritage of their former enemy. [45], The logical response to the convoy system, which concentrated forces for the defence, was to similarly concentrate the attacking force. With the war coming to an end, overwhelming allied forced all around them, Germany lost over 120 U-boats in action in the first 5 months of the year. On May 7, 1915, a German U-boat torpedoed the British-owned luxury steamship Lusitania, killing1,195people including 128Americans, according to the Library of Congress.

The sinking of Lusitania didnt directly cause the United States to enter the war. . Allied countermeasures during this period had mixed success. On May 7, 1915, German submarine U-20 torpedoed the Lusitania, a Cunard passenger liner, off the coast of Ireland. [29] In addition, UB-7 was reportedly sunk by Russian aircraft in October. Only 13 people died in the seven sinkings, their deaths caused by a capsized lifeboat. With the establishment of a comprehensive convoy system, Allied shipping losses fell to non-critical levels, while U-boat losses increased alarmingly. As they continued to divert blame, British propaganda against them snowballed.
