USS Sand Lance (SS-381)

Before entering her patrol area off Paramushiro on 24 February, she passed through two typhoons and encountered fields of slush ice and patches of drift ice. Sand Lance encountered her first victim, Kaika Maru, taking shelter from a blizzard in the lee of Paramushiro's southeast point. Her well-aimed torpedoes sent that enemy cargo ship to the bottom. Though her number-one periscope had been heavily damaged by drift ice, she pressed home attacks on a convoy on the night of 2 March and 3 March, sinking the 4521-ton cargo ship Akashisan Maru, and damaging other ships. A ship sunk by SS-381 on 3 March 1944 was the Soviet merchant ship "Byelorussia"[7]

On the night of 12–13 March, Sand Lance was running on the surface toward Honshū when a marauding airplane forced her to submerge. At about 0200, she came up to periscope depth and found herself in the midst of a Japanese convoy, consisting of five merchantmen and three heavily armed warships. Sand Lance had only six torpedoes remaining, but she made them count. She loosed four from the stern tubes and two from the bow tubes. All six hit the mark. Two of the four stern torpedoes hit a merchantman and the other two ripped into a light cruiser, while the two from the bow tubes smashed into another freighter. At least two of the ships went to the bottom, light cruiser Tatsuta and cargoman Kokuyo Maru, carrying over 1,000 enemy troops. For her success, Sand Lance underwent a 16-hour, 100-depth charge pounding from the accompanying destroyers. Finally, she was able to head home. She arrived in Pearl Harbor on 23 April 1944. The successes of her maiden war patrol brought Sand Lance a Presidential Unit Citation.

Sand Lance spent her second war patrol in the vicinity of the Marianas Islands and terminated it on the eve of the American invasion of those islands. She contributed to the success of that campaign by depriving the defending Japanese of the war material carried by five ships. On 3 May 1944, just north of Saipan, she torpedoed and sank the 3129-ton cargo ship Kenan Maru. Eight days later, she damaged Mitakesan Maru, a 4441-ton passenger cargo ship, while evading the bombs from an attacking enemy plane. Sand Lance sent the 4291-ton freighter Koho Maru to the bottom on 14 May off Apra Harbor, Guam, and found two more targets off Saipan on 17 May. This last attack, the sinking of Taikoku Maru and Fukko Maru, exhausted her supply of torpedoes, and she headed south to Fremantle, Australia, arriving on 5 June 1944.

The submarine put to sea on 3 July to patrol the Molucca Sea and Celebes Sea. She sank the converted gunboat Taiko Maru on 14 July and damaged another ship in the same attack. Four days later, she received a good shaking from fast patrol craft while trying to press an attack on a large transport in the Sulu Islands. Sand Lance did not find another target until 1 August when she damaged a freighter south of Lombok Island. Two days later, she barely escaped the bombs of a plane which almost caught her in the shallow waters of Amoesang Bay. She sped back through the entrance to the bay and the safety of deeper water.

More bombs exploded astern on the morning of 6 August as she stalked some small freighters along the coast of Celebes. The force of the explosion lifted her several feet and damaged her port shaft.

Soon, the submarine had two additional problems, enemy escorts bearing down on her and a torpedo running hot in one of her stern tubes. Sand Lance came up to 100 feet (30 m) and fired the torpedo. Eight seconds later, it exploded prematurely, adding to the damage to her stern. Fortunately, the explosion apparently convinced the Japanese that they had destroyed the submarine, for Sand Lance received no further attacks. She surfaced after dark, but the damaged gear could not be repaired. Forced to make the voyage back to Fremantle on one shaft, she made port on 19 August. On 10 September, she headed east for Pearl Harbor and, from there, on to Mare Island Naval Shipyard, where she arrived on 1 November.

Repairs were completed by 13 March 1945 when she sailed back to Pearl Harbor. On her fourth war patrol from 10 April to 6 June 1945, Sand Lance encountered only one target, an unidentified coastal freighter which she torpedoed on 14 May. She departed from her patrol area, along the coasts of Honshū and Hokkaidō, and returned to Midway Island on 6 June. One month later, she sailed from Midway on her fifth and last war patrol. She fueled at Saipan, then took up lifeguard station for the bombers raiding the Japanese home islands. Hostilities ceased on 15 August, and, on the next day Sand Lance made for San Francisco, California, via Midway and Pearl Harbor. She entered the San Francisco Naval Shipyard at Hunter's Point on 7 September for inactivation overhaul. Sand Lance decommissioned at San Francisco on 14 February 1946.

Sand Lance remained inactive until designated for loan to the Brazilian Navy under the terms of the Military Assistance Program. After reconditioning, she recommissioned at Pearl Harbor on 6 April 1963 with Commander Carl H. Sebenius Jr., in command. She departed Pearl Harbor on 24 June and made San Francisco on 1 July to embark officers and men of the Brazilian Navy for training. The training was completed by 7 September 1963 when she was decommissioned and loaned to Brazil.

On transfer she was renamed Rio Grande do Sul (S-11) (variously misspelled in American records as "...de Sol," "...del Sol," &c.) and served for eight years in the Brazilian Navy.

On 15 September 1972, Brazil returned her (at least on paper), and promptly purchased her back for US$55,000 on 12 October. Upon that purchase, Sand Lance was struck from the Naval Vessel Register.

Brazil cannibalized the submarine for parts and within three years the boat was reduced to scrap.

Sand Lance (SS-381) earned five battle stars and a Presidential Unit Citation (US) for World War II service.
