In the mid-1943, following the Guadalcanal campaign, the Allies launched their next offensive in the Solomon Islands. Their objective was to seize the major Japanese Airstrip at Munda on New Georgia Island. As a preliminary step, the US forces landed troops on the island of Rendova on the 30th of June. The goal was to set up an initial beachhead from which they could move troops across Blanche Channel to New Georgia. After securing Rendova, the US forces initiated the westward advance towards Munda.

On the afternoon of the 5th of July, Rear Admiral Walden L. Ainsworth's US Navy Task Group 36.1, consisting of light cruisers USS Honolulu, USS St. Louis, and USS Helena, along with four destroyers - Nicholas, O'Bannon, Radford, and Jenkins - were returning to the Coral Sea to resupply. However, they were redirected to intercept a Japanese Tokyo Express mission down the Slot in the Solomon Islands.

The Japanese sought to reinforce the Munda area by moving troops and supplies via barge from the shortlands via Kolambongara. In the early hours of the morning, Ainsworth's task force encountered a Japanese naval reinforcement group off the coast of Kolambongara, consisting of two transport units carrying troops and escorted by Admiral Teru Akiyama's support unit. The Japanese force included a total of ten destroyers.
