On July 6, 1942, the Japanese moved a force consisting of troops and labourers to Guadalcanal in the Solomon Islands and began constructing an airfield. The Allies recognized that land-based planes operating from this field would seriously menace bases in the New Hebrides and New Caledonia as well as Port Moresby in New Guinea. Immediate steps were taken to eject the Japanese, utilizing forces that were available in the South Pacific.

On August 7, 1942, some 6,000 men of the U.S. 1st Marine Division, commanded by Maj. Gen. Alexander Vandegrift, launched an amphibious assault on Guadalcanal and Florida Island, surprising Guadalcanal’s 2,000 Japanese defenders. The landings were made with strong naval and air support and met with little initial resistance, and the airfield on Guadalcanal and the harbour on Florida Island were seized in the first 36 hours. The Marines named the airstrip Henderson Field, after Maj. Lofton Henderson, a Marine aviator who had perished while leading a bombing run at the Battle of Midway the previous month. Henderson Field would quickly become the centre of gravity for the conflict on Guadalcanal.

The Japanese reacted quickly, and just before 2:00 AM on August 9 they struck hard at the Allied naval force supporting the operation. A force of Japanese cruisers and destroyers engaged the Allied fleet in a furious night battle that came to be called the Battle of Savo Island. The result was a disaster for the Allies. Over the course of roughly a half hour, the Japanese sank the U.S. cruisers Astoria, Quincy, and Vincennes and crippled the Australian cruiser Canberra while suffering negligible losses.

Over the following months, some two dozen Japanese and Allied ships would be sunk in the waters to the north of Guadalcanal; the sea lane between Guadalcanal and Florida Island would subsequently be known to Allied sailors as Ironbottom Sound.

… a Japanese resupply convoy under the command of Rear Adm. Tanaka Raizo attempted to force its way through to Guadalcanal without the benefit of air cover on the morning of August 25. Dive-bombers from Guadalcanal struck Tanaka’s flagship, the cruiser Jintsu, and inflicted heavy damage on a Japanese troop ship. U.S. Army Air Forces B-17s scored a direct hit on the destroyer Mutsuki, sinking it. Tanaka was forced to retire, but he quickly revised his tactics, and his destroyer squadron—the so-called “Toyko Express”—would ferry tens of thousands of Japanese troops and tons of vital supplies to Guadalcanal over the following months.


Two weeks later the much larger Battle of Santa Cruz occurred against the backdrop of a major Japanese ground offensive on Guadalcanal. U.S. commanders were anticipating a Japanese attack, and Vice Adm. William (“Bull”) Halsey, who had succeeded Ghormley as commander of U.S. naval forces in the South Pacific on October 18, concentrated his available assets into two carrier battle groups. The aircraft carrier USS Enterprise, which had spent nearly a month at Pearl Harbor undergoing repairs, sailed with the battleship USS South Dakota, the heavy cruiser USS Portland, and a screen of light cruisers and destroyers.

The carrier USS Hornet was supported by the heavy cruisers USS Northampton and USS Pensacola and a light cruiser and destroyer escort. Against this force was arrayed Vice Adm. Nagumo Chuichi’s fleet carriers Shokaku and Zuikaku—both of which had participated in the Pearl Harbor attack—the light carrier Zuiho, the escort carrier Junyo, four battleships, and an assortment of destroyers and other support craft.

The two forces met north of Guadalcanal on October 26, and the result was a tactical victory for Japan. The Hornet was sunk, as was the destroyer USS Porter, and the Enterprise was seriously damaged. Nagumo was forced to retire, however, as the Zuiho and the Shokaku had suffered numerous bomb hits and the loss of nearly 100 aircraft had left him without a significant portion of his naval air complement. The Japanese retreat bought the Americans a much needed breathing spell.
