The Marine pilots shot down three B5Ns on their first pass and severely damaged another pair which were also forced to crash-land. The US fighters then shot down the three remaining bombers after they missed Lardner. The defending Zeros were able to shoot down only one Wildcat at the cost of one of Hiyōs fighters forced to crash land, although they claimed to have shot down thirteen Marine fighters. A fire in the ship's generator room occurred on 21 October and reduced her top speed to so Kakuta transferred his flag to Jun'yō while Hiyō returned to Truk for repairs. Three Zeros, one D3A and five B5Ns were also transferred to Jun'yō before she left. The remaining aircraft of her air group (16 Zeros and 17 D3As) were flown off for Rabaul, on the island of New Britain, on 23 October, from where the fighters escorted bombers attacking Guadalcanal the following day. A detachment from the air group was transferred to Buin, New Guinea, on 1 November and attacked American ships off Lunga Point on 11 November. Escorted by 18 Zeros from Hiyō and the 204th Naval Air Group, 9 D3As slightly damaged three cargo ships in exchange for 4 dive bombers shot down and another forced to crash land. The Zeros were able to ambush six Wildcats in the heavy cloud and shot down four while losing two of their own. That same day, those aircraft that remained at Rabaul flew back to Truk, but the Buin detachment remained there until 14 December when they were ferried back to Japan. Captain Michio Sumikawa relieved Beppu on 30 November. Hiyō spent November in Truk before returning to Japan in early December where she was rejoined by the rest of her air group. Aside from a brief refit at Kure from 26 February to 4 March 1943 that saw her anti-aircraft armament augmented and an additional radar installed, the ship was training in the Inland Sea until she sailed for Truk on 22 March. Her air group consisted of 27 Zeros and 12 D3As and they were detached from Hiyō in early April to participate in Operation I-Go, a land-based aerial offensive against Allied bases in the Solomon Islands and New Guinea. On 7 April her aircraft formed most of the third wave of attacks on Guadalcanal. Escorted by 24 Zeros from Hiyō and another 6 from the light carrier ,
