ww2dbaseI-58, a 2140-ton "B(3) Type" submarine, was built at Yokosuka, Japan. Completed in September 1944, she was modified in 1945 to carry the "Kaiten" manned torpedo. Her captain, Lieutenant Commander Mochitsura Hashimoto, did not get a chance to attack an enemy ship until 30 Jul 1945, when she ran across the unescorted heavy cruiser Indianapolis between the Marianas and the Philippines. After confirming the Indianapolis as a hostile warship (though misidentifying her as a battleship), Hashimoto launched six conventional torpedos toward the American cruiser. Each torpedo carried 1,210 pounds of explosives. Two of them scored hits, and sank the Indianapolis within minutes. Due to a series of miscommunication and blunders by the US Navy, the sinking of the Indianapolis went unnoticed for several days before a rescue effort was launched. Of the approximately 900 men who survived the explosions and the sinking, only 316 survived the shark-infested waters of the Pacific with little food and no water to tell the tale.

I-58 Operational Timeline

10 Dec 1941 Japanese submarine I-58 spotted British battleship HMS Prince of Wales and battlecruiser HMS Repulse off British Malaya, launched five torpedoes, but all of them missed; beginning at 1117 hours, Japanese aircraft began to attack. Overwhelmed, HMS Repulse was sunk at 1233 hours (513 killed), followed by HMS Prince of Wales at 1318 hours (327 killed); destroyers HMS Electra, HMS Express, and HMS Vampire rescued 1,862 survivors. On land, the British commanders dispatched the 1st Battalion of the 14th Punjab Regiment and the 2nd Battalion of the 1st Gurkha Rifles regiment to Changlun and Asun in northern British Malaya to counter the Japanese advance; contact was made at Changlun at 2100 hours, where two Japanese tanks were destroyed before the Punjabi troops fell back toward Asun.
9 Jan 1942 Japanese submarine I-58 sank Dutch ship Camphuijs in the Java Sea.
1 Apr 1946 I-58 was decommissioned from service.
