Dunkley and his colleagues examine the wrecks with ultrasound sonar devices they wear on their wrists like watches. All of the sunken U-boats are relatively close to the coast, at depths of no more than 15 meters (about 50 feet). January 13. The first success was the sinking of U-68 off Kerry, Ireland, on 22 March 1916 by the Q-ship Farnborough.

At the beginning of the war, there were only 28 U-boats under the supreme command of Kaiser Wilhelm II, a tiny number compared to the Allied fleet. The might of the U-boat, however, wasn't enough to hold back the combined strength of U.S. and British forces, including the ongoing blockade that ultimately strangled Germany's access to key resources like raw materials and food. [44] Said Winston Churchill, First Lord of the Admiralty, The poor babies who perished in the ocean struck a blow at German power more deadly than could have been achieved by the sacrifice of 100,000 men..
