Guadalcanal’s Naval Battle Opened

On 12 November 1942, Allied and Japanese naval forces began fighting in the Solomon Islands in what became the Naval Battle of Guadalcanal. It continued through 15 November. The Americans prevailed after days of intense fighting, and the engagement helped isolate the Japanese forces still on Guadalcanal.

The contest came during a wider struggle for the island. American forces had landed on Guadalcanal on 7 August, beginning the first American ground operations in the long campaign against Japan. By November, the battle at sea had become closely tied to the fate of Japanese forces ashore: the outcome, as the fighting ran through four days, was their isolation. Japan lost the battleships Hiei and Kirishima, and its attempt to reinforce the island in strength failed; the Americans lost the cruisers Atlanta and Juneau, and Rear Admirals Daniel Callaghan and Norman Scott were killed.

The date also fell amid a rapidly widening Allied offensive. Four days earlier, on 8 November, American and British forces had landed in French North Africa under Operation Torch. In late October, British forces had inflicted a decisive defeat on Erwin Rommel’s army at El Alamein. The naval fighting off Guadalcanal therefore unfolded while Allied operations were advancing in two other theaters, though the immediate consequence described for the battle was local: Japanese forces remaining on the island were isolated.

That distinction mattered. Guadalcanal’s naval battle was not simply a clash recorded alongside the island campaign; its result bore directly on the forces still there. The fighting ran from 12 to 15 November, and the Americans held the field. By 15 November, the naval battle had ended with the Japanese forces on Guadalcanal isolated, as the Allied effort in the Pacific continued.
