anchorage there on 7 November 1943. She suffered a diesel engine breakdown on 12 November and on 13 November 1943 was ordered back to Truk, which she reached safely. Departing Truk on 24 November 1943, I-32 called at Kwajalein from 27 November to 5 December 1943. She returned to Truk on 8 December 1943, took aboard torpedoes from the auxiliary submarine tender on 10 December, then put to sea on 14 December 1943 bound for Japan, where she arrived at Kure on 20 December 1943 for an overhaul. February–March 1944 With her overhaul complete, I-32 departed Kure on 28 February 1944 bound for Truk, which she reached on 8 March 1944. During her stay in Japan, American forces had captured Kwajalein, Majuro, and Eniwetok in the Marshall Islands, leaving some bypassed Japanese garrisons in the islands isolated. On 15 March 1944, I-32 departed Truk on a run to carry supplies to the isolated garrison on Wotje Atoll, with orders to follow delivery of the supplies with an anti-shipping patrol in the Pacific Ocean east of the Marshalls. During her voyage to Wotje, she reported sighting an American carrier plane south-southwest of Kusaie at 14:30 Japan Standard Time on 17 March 1944, and on 23 March 1944 at 22:21 Japan Time she reported sighting an Allied task force. It was the last time that the Japanese ever heard from I-32. Loss Fleet Radio Unit Pacific, a U.S. Navy signals intelligence and cryptanalysis organization in Hawaii, intercepted and decrypted I-32′s 23 March 1944 message. Based on the information, a U.S. Navy hunter-killer group made up of the destroyer , the destroyer escort , and the submarine chaser rendezvoused at Erikub Atoll and set out to intercept I-32. At 04:22 on 24 March 1944, Manlove detected a surfaced submarine south of Wotje on radar at a range of . Manlove closed with the submarine, which submerged when she was away, causing Manlove to lose radar contact. Manlove quickly gained sonar contact on the submarine, however, and Halsey Powell moved in, expending all of her depth charges in a series of attacks. Manlove and PC-1135 then attacked, Manlove dropping depth charges and firing Hedgehog salvos and PC-1135 attacking with Mousetrap projectiles. The submarine sank at . The submarine Halsey Powell, Manlove, and PC-1135 sank probably was I-32. On 24 March 1944, the Imperial Japanese Navy declared her to be presumed lost with all hands.
