Excerpt: SM UC-42 was a German Type UC II minelaying submarine or U-boat in the German Imperial Navy (German: ) during World War I. The U-boat was ordered on 20 November 1915 and was launched on 21 September 1916. She was commissioned into the German Imperial Navy on 18 November 1916 as SM UC-42. In a career that encompassed six patrols, operating from 1 January 1917, UC-42 succeeded in sinking thirteen vessels totaling 9,636 tons, and disabling a warship of 1,210 tons displacement. UC-42 sailed on her last patrol on 1 September 1917. On 31 October 1917 Torpedo Boat TB 055 was accompanying minesweepers operating at the entrance to Cork harbour. At 1500 hours an oil track was seen floating on the surface of the water. Following it to its source, TB 055 used its hydrophone to see if the oil was coming from a submarine. Loud mechanical sounds, of "hammering" and "turbine-like noises" were reported and, believing this to be a U-boat, a marker buoy was dropped, followed shortly after by a depth charge. Following detonation of the charge, TB 055 returned to the area and found that the volume of floating oil had increased, and there were bubbles rising to the surface. TB 055 signalled the nearby armed minesweeper HMT Sarba for assistance. Sarba used her hydrophone but detected no sounds from the presumed submarine. A second depth charge was dropped and Sarba remained on station overnight. The following morning HMD Sunshine and TB 058 swept around the spot, to confirm that the incident had not been a false alarm caused by old wreckage. On 2 November oil was still coming to the surface and dockyard divers arrived to inspect the assumed wreck. The divers reported a German U-boat lying on the seabed with her stern blown off, and a brass plate on her conning tower reading "C42, 1916" identified her as UC-42. No survivors were ever reported even though some of the hatches were found to have been opened. It was thought likely that the submarine had been sunk by one of her own mines detona
