Her surviving crew abandoned ship, after which I-10 surfaced and fired nine rounds at Alchiba. Alchiba broke in two and sank at . Some of her survivors mistakenly claimed that two submarines had attacked her. I-10 returned to Penang on 30 July 1942. August–October 1942 I-10 departed Penang on 1 August 1942 bound for Yokosuka, which she reached on 12 August. She remained in Japan until 21 October 1942, when she departed Yokosuka heading for Truk Atoll. She arrived at Truk on 27 October 1942. Guadalcanal campaign The Guadalcanal campaign had begun with United States Marine Corps landings on Guadalcanal in the southeastern Solomon Islands on 7 August 1942. While I-10 was at Truk, she was reassigned to the "C" Patrol Unit on 31 October 1942. On 24 November 1942 she got underway from Truk to patrol off San Cristobal in support of a midget submarine attack against Allied shipping in Lungga Roads off the north coast of Guadalcanal. She returned to Truk on 18 December 1942. Third war patrol With a Yokosuka E14Y1 (Allied reporting name "Glen") floatplane aboard, I-10 departed Truk on 5 January 1943, ordered to attack Allied shipping south of the Solomon Islands and conduct a reconnaissance of Nouméa on Grande Terre in New Caledonia, of New Zealand waters, and of the Torres Strait. She passed east of the Solomons on 10 January. She sighted what she identified as an aircraft carrier escorted by two destroyers on 16 January south-southeast of Nouméa and attempted a pursuit and attack, but she failed to achieve a good attack position and all of her torpedoes missed. At 00:15 on 20 January 1943 she sighted what she identified as an unescorted transport south of Nouméa, and at 00:20 on 23 January she sighted two destroyers east of Nouméa. After dark on 24 January, she launched her floatplane for a reconnaissance flight over the Nouméa area — at a time when United States Secretary of the Navy Frank Knox and the Commander-in-Chief of the United States Pacific Fleet, Chester W. Nimitz, were in Nouméa for a Commander, South Pacific Area conference — and at 01:00 on 25 January its crew reported seeing several battleships, cruisers, destroyers, and transports in the harbor. On 30 January 1943, I-10 was in the Coral Sea south of the Amédée Lighthouse on Amédée Island in New Caledonia when she hit the American 7,176-gross register ton Liberty
