The Battle of Kolombangara (Japanese: コロンバンガラ島沖海戦) was a naval battle of the Pacific campaign of World War II, fought on the night of 12 July, 1943 – 13 July, 1943 off Kolombangara in the Solomon Islands.

Background

A Japanese "Tokyo Express" reinforcement force, commanded by Rear Admiral Shunji Izaki and comprising the light cruiser Jintsu, the destroyers Mikazuki, Yukikaze, Hamakaze, Kiyonami and Yugure and the destroyer transports Satsuki, Minazuki, Yunagi, and Matsukaze, made a run down "The Slot" from the upper Solomons to land troops at Vila on Kolombangara by way of Kula Gulf on the night of 12 July 1943.

An Allied force, commanded by Rear Admiral Walden L. Ainsworth and comprising the light cruisers USS Honolulu, USS St. Louis and HMNZS Leander, and the destroyers Nicholas, O’Bannon, Taylor, Jenkins, Radford, Ralph Talbot, Buchanan, Maury, Woodworth and Gwin, were deployed in a single column with five destroyers in the van followed by the cruisers and five destroyers in the rear.

The United States had landed troops of the 37th Infantry Division on New Georgia to attack Munda the week before, and had just placed Marine Raiders ashore at Rice Anchorage on its northern shore to seize Bairoko. Admiral Ainsworth's mission was to protect the north shore beachhead from attack by the "Tokyo Express" and if possible to prevent reinforcements from landing.

Battle

At 01:00 on 13 July the Allied ships established radar contact about twenty miles (30 km) east of the northern tip of Kolombangara. Ainsworth assumed he had complete surprise but the Japanese had been aware of the Allied force for almost two hours. The destroyers increased speed to engage the Japanese force while the cruisers turned to deploy their main batteries but the Japanese destroyers had already launched torpedoes and turned away. Jintsu engaged the Allied ships but all American fire was concentrated on the largest ship and she was reduced to a wreck while Leander was struck by a torpedo and, severely damaged, retired from the battle escorted by Radford and Jenkins. Jintsu was finally broken in two by torpedo hits and sank at about 01:45, with the loss of nearly the entire crew, including Admiral Izaki.

Ainsworth pursued the Japanese destroyers but both St. Louis and Honolulu were struck by torpedoes and damaged while Gwin was struck amidships and scuttled at 09:30 the next morning.

Aftermath

Honolulu and St. Louis were out of action for several months while Leander was under repair for a year and never returned to action.

Except for Jintsu the Japanese force escaped damage and the transport destroyers successfully landed 1,200 men at Vila. The Japanese had won a tactical victory, but of the action the naval historian Samuel Eliot Morison wrote: "A string of such victories added up to defeat."

Though at a severe cost, Ainsworth also accomplished his mission of preventing an attack on the Marines, and combined with the earlier Battle of Kula Gulf, successfully deterred the Japanese from future use of Kula Gulf in reinforcing Munda. After the battle off Kolombangara the Japanese chose to use Vella Gulf, Blackett Strait, and the more constricted passage at Wana Wana, resulting in a series of nightly attacks by U.S. destroyers and PT Boats against their reinforcement efforts.
