USS Grenadier (SS-210)
USS "Grenadier" (SS-210), a , was the first ship of the United States Navy to be named for the grenadier fish, relatives of cod that are very common in bathyal and abyssal habitats. Construction and commissioning. "Grenadier"′s keel was laid down by Portsmouth Navy Yard in Kittery, Maine, in April 1940. She was launched on 29 November 1940, sponsored by Mrs. Virginia E. Anderson, wife of Rear Admiral Walter S. Anderson, Director of Naval Intelligence. "Grenadier" was commissioned on 1 May 1941 with Lieutenant Commander Allen R. Joyce in command. Pre-World War II service. On 20 June  1941 "Grenadier" participated in the search for , which had failed to surface after a deep test dive, and was present two days later as memorial exercises were conducted over the spot where "O-9" and her crew lay. After shakedown in the Caribbean Sea, "Grenadier" returned to Portsmouth on 5 November for refit. Less than three weeks after the Japanese attack on Pearl Harbor, she sailed for the Pacific to join the submarine fleet. COMSUBPAC patrols, 1942. "Grenadier"s first war patrol from 4 February to 23 March 1942 took her near the Japanese home islands, off the coast of Honshū, and  brought her several targets but no sinkings. On 12 April "Grenadier," now under command of LCDR Willis Lent, departed Pearl Harbor for her second war patrol, along the Shanghai-Yokohama and Nagasaki-Formosa shipping lanes. On 8 May she torpedoed and sank one of her most important victories of the war, transport . Post-war examination of Japanese records showed "Taiyō Maru" to be more than just the ordinary transport; she was en route to the East Indies with a group of Japanese scientists, economists, and industrial experts, including renowned hydraulic engineer Yoichi Hatta who designed Chianan Irrigation and built Wusanto  Reservoir in Taiwan, bent on expediting the exploitation of the conquered territory. Their loss was a notable blow to the Japanese war effort. On 25 May "Grenadier" was diverted from her patrol area to Midway Island, where she formed part of the submarine patrol line as the American fleet in a bloody but brilliant battle handed the Imperial Navy its first defeat in some three hundred years. "Grenadier"s third war patrol was in the Truk area, heavily patrolled by enemy ships and planes. Although she sighted some 28 Japanese ships, enemy planes effectively hampered her, and she returned to her  new base, Fremantle, Australia, empty-handed. Deployment to Australia. The Malay Barrier was the site of "Grenadier"s fourth war patrol from 13 October to 10 December. After laying a minefield off Haiphong, Indochina, the submarine made an unsuccessful attack on a large freighter. During the severe depth charging which followed, sea water seeped into the batteries; "Grenadier"s crew suffered headaches and nausea from chlorine gas poisoning for the remainder of the patrol. On 12 November, she attacked and sank by torpedo the rescue tug () off the coast of Vietnam (11°18'N 109°02'E). To increase the misery, on  20 November "Grenadier" spotted a -class aircraft carrier, escorted by a cruiser and a destroyer, heading through the Strait of Makassar too distant to shoot. "Grenadier" surfaced to radio the aircraft carrier's location and course to Fremantle submarine base in hope that another submarine could capitalize on it. "Grenadier"s fifth war patrol, under the command of LCDR John Allison Fitzgerald, between 1 January and 20 February 1943, brought her considerably better fortune than earlier patrols. A 75-ton schooner fell victim to her deck guns 10 January, and two days later "Grenadier" sighted a small tanker with a barge  in tow. Judging the target not worth a torpedo, she slipped silently into the column behind the two Japanese ships. At dusk she battle surfaced. With binoculars lashed to the deck guns as sights, she raked the tanker and barge, sinking them immediately. The remainder of her patrol, along the Borneo coast through shallow and treacherous waters, was hampered by fathometer failures. She conducted an aggressive attack on two cargo ships 22 January but did not sink them. The submarine departed Australia on 20 March on her last war patrol and headed for the Strait of Malacca, gateway between the  Pacific and Indian Oceans. Patrolling along the Malay and Thai coasts, "Grenadier" claimed a small freighter off the island of Phuket on 6 April. She remained in the area and late in the night of 20 April sighted two merchantmen and closed in for the attack. Running on the surface at dawn 21 April, "Grenadier" spotted, and was simultaneously spotted by, a Japanese plane. The submarine dived, and as it passed her executive officer commented, "We ought to be safe now." Just then, explosions rocked "Grenadier" and heeled her over 15 to 20 degrees. Power and lights failed completely and  the fatally wounded ship settled to the bottom at . She tried to make repairs, while a fierce fire blazed in the maneuvering room. After 13 hours of sweating it out on the bottom "Grenadier", managed to surface after dark to clear the boat of smoke and inspect damage. The damage to her propulsion system was irreparable. Attempting to bring his ship closer to shore so that the crew could scuttle her and escape into the jungle, Commander Fitzgerald even tried to jury-rig a sail. But the long night's work proved futile. As dawn broke on 22 April, "Grenadier"s  weary crew sighted two Japanese ships heading for them. The skipper "didn't think it advisable to make a stationary dive in 280 feet of water without power," and the crew began burning confidential documents prior to abandoning ship. A Japanese plane attacked the stricken submarine, but "Grenadier", though dead in the water and to all appearances helpless, blazed away with her machine guns. She hit the plane on its second pass. As the damaged plane veered off, its torpedo landed about from the boat and exploded. Loss. Opening all vents, the crew of "Grenadier" abandoned ship and watched her  sink to her final resting place. A Japanese merchantman picked up eight officers and 68 enlisted men and took them to Penang, Malay States, where they were questioned, beaten, and starved before being sent to other prison camps. They were then separated and transferred from camp to camp along the Malay Peninsula and finally to Japan. Throughout the war they suffered brutal, inhuman treatment, and their refusal to reveal military information frustrated and angered their captors. First word that any had survived "Grenadier" reached Australia on 27 November 1943. Despite the brutal and sadistic treatment, all but four of "Grenadier"s  crew survived their two years in Japanese hands. "Grenadier" received four battle stars for World War II service. Discovery of wreck. A sunken wreck identified as the "Grenadier" was found by a team of four divers—Jean Luc Rivoire, Lance Horowitz, Benoit Laborie and Ben Reymenants—sitting upright under about of water and partly covered in fishing nets. Announced in 2020, the discovery of the wreck came in a series of dives as part of a six-month, $110,000 expedition beginning in October 2019. The divers sent their findings to the Naval History and Heritage Command for verification; confirmation  will place the wreck under the protections of the Sunken Military Craft Act.
