On October 14, 1942 at 1:33am floatplanes release flares to mark Henderson Field on Guadalcanal. At 1:37am Kongō and Haruna commence a shore bombardment of Henderson Field on Guadalcanal. Meanwhile, Isuzu and destroyers provide covering firing targeting shore batteries. The force steams eastward passing Lunga Point firing to starboard, then made a 180 degree turn and fires to port while departing. On the ground, the shelling damaged the two runways, burned fuel and destroyed 48 parked planes and resulted in 41 KIA. Although PT Boats attempt to intercept, they are driven away by Naganami. At 2:30am the force retires northward up "The Slot" at 29 knots.

Assigned to the Northern Mobile Force under the command of Admiral Jisaburo Ozawa that will serve as a decoy to divert American aircraft carriers.

The Northern Mobile Force includes Carrier Division 1 Zuikaku and Zuihō, Chitose and Chiyoda screened by Isuzu with destroyers Kuwa, Sugi, Maki, Kiri, Akizuki, Hatsuzuki, Wakatsuki and Shimotsuki. Carrier Division 4 Hyuga and Ise screened by light cruiser Oyodo and Tama.

At 8:35am the planes score a hit on Chitose that floods, lost power and develops a list. At 9:25am Isuzu unsucessfully attempts to tow the damaged carrier before it rolls over and sinks twelve minutes later. Afterwards, Isuzurescues 480 crew and Shimotsuki rescues 121 crew before they withdraw with black smoke on the horizon as U.S. warships approach.

PARTIAL HISTORY

On April 4, 1945 departs Surabaya (Surabaja) with an Army detachment aboard to transport them to Bima on Sumbawa Island escorted by torpedo boat Kari and minesweeper W-12 and minesweeper W-34. Off Paternoster Island, the group is spotted by by a U.S. Navy submarine wolf pack including USS Charr (SS-328), USS Besugo (SS-321) and USS Gabilan (SS-252) and two days later are joined by HMS Spark. The presences of Japanese planes force the submarines to dive and are unable to attack. Afterwards, shadowed by a RAAF Mosquito from No. 87 Squadron until spotted by a Japanese plane and driven off.

On April 6, 1945 bombed by NEIAF B-25 Mitchells from No. 18, Squadron that scored a near miss off her starboard bow. Later in the day, she disembarked the Army soliders at Bima Bay on Sumbawa Island then withdrew into the Java Sea. Next, bombed off Flores Island by RAAF B-24J Liberators from No. 21 Squadron an No. 24 Squadron that score a direct hit on the bow but the bomb was a dud and two near misses around 9:40am that disable steering and require manual steering. During the strike, two Liberators were shot down by Japanese Army Air Force (JAAF) fighters. Later, USS Besugo (SS-321) fired nine torpedoes at the convoy and hit an escorting minesweeper.

Sinking History
On April 7, 1945 while in the Java Sea off Sumbawa Island hit by a torpedo in the port side causing flooding as one of five fired by USS Gabilan (SS-252). The damage caused her speed to drop to below 10 knots and began to list to port and settle by the bow. As her crew attempted emergency repairs, USS Charr (SS-328) fired torpedoes with two hitting the port side near the aft engine room then fired two more torpedoes that hit the bow causing it to break off and sink at roughly sank at roughly Lat 7°38′S Long 118°09′E. A total of 190 crew were lost in the attacks and sinking. Officially removed from the Navy list on June 20, 1945.
