At 20.46 hours on 1 May 1942 the unescorted and neutral Parnahyba (Master Raul Francisco Diegali) was hit on the port side aft of amidships in the empty port bunker by one G7e torpedo from U-162 while steaming on a non-evasive course at 10.5 knots in clear weather and calm sea about 220 miles east of Trinidad. The ship was flying a Brazilian flag but was attacked without warning because she was armed with a 5in gun aft. The crew of 71 men and one passenger immediately abandoned ship in three lifeboats after sending a distress signal, although she was only settling slowly by the stern. The U-boat surfaced 10 minutes later and finished off the Parnahyba with 66 rounds from the deck gun and 20 rounds from the 37mm anti-aircraft gun. The ship caught fire and sank by the bow after two hours and a half. In the afternoon of 3 May, the 26 occupants of one lifeboat were picked up by the Canadian motor merchant Turret Cape and landed at Georgetown the next day. Another lifeboat with 16 occupants made landfall on Trinidad and the remaining survivors were picked up by the Spanish steam passenger ship Cabo de Hornos and taken to Rio de Janeiro.
