[tater]

At 01.35 hours on 13 Sep, 1942, the unescorted Patrick J. Hurley (Master Carl Stromgren) was attacked with all guns by U-512 about 950 miles northeast of Barbados just when a lookout spotted the U-boat about 150 yards off the starboard bow, running parallel to the ship. The U-boat had missed the tanker with a torpedo during daylight the day before and apparently had a long time to catch the tanker, which was running at 15 knots. The gunfire hit the midships cabins, destroyed the radio antenna, wrecked the lifeboats, destroyed the forward 3in gun (the ship was armed with one 4in, one 3in, two 50mm and two 20mm guns), damaged the engine room and holed the tanker at the waterline, starting a fire in the cargo.
The tanker increased speed to about 17 knots and tried to escape by evasive maneuvres, while the armed guards fired six rounds from the stern gun and the 20mm guns, but to no avail. The U-boat fired about 30 shells, which turned the ship into a flaming inferno within ten minutes and caused her to sink shortly after dawn. The most of the ten officers, 34 crewmen and 18 armed guards on board abandoned ship in two lifeboats and two rafts when she was still under way and later redistributed into the two boats. The master, three officers, nine crewmen and four armed guards were lost.

Caught a tanker on fire, and it took a few hours to sink, looks like (attack at 1:35, sinking near dawn). 30 rounds from the DG.

Only one large ship was sunk by a US boat in the whole war with the DG. Very few above 1000 tons were ever even fired on by USN boats.
