a diesel fuel leak soon afterward and received orders to abort her patrol and return to Truk, where she called from 6 to 7 October 1942 before getting back underway bound for Kure, which she reached on 13 October 1942. She underwent repairs at Kure. New Guinea campaign, December 1942–January 1943 With her repairs complete, I-32 left Kure on 4 December 1942 bound for Truk, then got underway from Truk on 14 December 1942 making for Rabaul on New Britain. During her voyage, she was submerged in the Bismarck Sea off the Admiralty Islands on 16 December 1942 when she detected a surfaced Allied submarine at 22:00 and began an approach, but the submarine dived before she could attack. She arrived at Rabaul on 17 December 1942. Upon arrival at Rabaul, I-32 was assigned to Submarine Group B, and she began a series of supply runs to New Guinea to support Japanese forces fighting in the New Guinea campaign. Carrying a cargo of 22 tons of food and ammunition, she departed Rabaul on her first run on 19 December 1942, arrived off the Mambare River estuary at Buna on the coast of New Guinea on 24 December 1942, got back underway the same day after unloading her cargo, and returned to Rabaul on 26 December 1942. Her second supply run was unsuccessful: She departed Rabaul on 27 December and arrived at the Mambare River on 29 December, but after failing to contact any Japanese forces ashore she headed back to Rabaul, arriving there with her cargo still aboard on 31 December 1942. I-32 made two more supply runs in January 1943, departing Rabaul on 7 January, arriving off the Mambare River estuary to unload her cargo and embark 43 passengers on 9 January, calling at Rabaul from 11 to 12 January, and returning to the Mambare River on 14 January, where she unloaded 22 tons of food and ammunition. She then headed for Truk, where she arrived on 18 January 1943. Third and fourth war patrols On 24 January 1943, I-32 departed Truk to begin her third war patrol, assigned to a submarine patrol line south of Guadalcanal, where the six-month Guadalcanal campaign was in its final stages. It concluded while I-32 was on patrol, when the Japanese completed Operation Ke, the evacuation of their forces from the island, on 8 February 1943. On 11 February, I-32 sighted a U.S.
