Marines in World War II Commemorative Series: Cape Gloucester: The Green Inferno, Major General WIlliam Rupertus, New Britain, Borgen Bay, Volupai-Talasea, LCMs, DUKWs

On the early morning of 26 December 1943, Marines poised off the coast of Japanese-held New Britain could barely make out the mile-high bulk of Mount Talawe against a sky growing light with the approach of dawn. Flame billowed from the guns of American and Australian cruisers and destroyers, shattering the early morning calm. The men of the 1st Marine Division, commanded by Major General William H. Rupertus, a veteran of expeditionary duty in Haiti and China and of the recently concluded Guadalcanal campaign, steeled themselves as they waited for daylight and the signal to assault the Yellow Beaches near Cape Gloucester in the northwestern part of the island. For 90 minutes, the fire support ships blazed away, trying to neutralize whole areas rather than destroy pinpoint targets, since dense jungle concealed most of the individual fortifications and supply dumps. After the day dawned and H-Hour drew near, Army airmen joined the preliminary bombardment. Four-engine Consolidated Liberator B-24 bombers, flying so high that the Marines offshore could barely see them, dropped 500-pound bombs inland of the beaches, scoring a hit on a fuel dump at the Cape Gloucester airfield complex and igniting a fiery geyser that leapt hundreds of feet into the air. Twin-engine North American Mitchell B-25 medium bombers and Douglas Havoc A-20 light bombers, attacking from lower altitude, pounced on the only Japanese antiaircraft gun rash enough to open fire.

The warships then shifted their attention to the assault beaches, and the landing craft carrying the two battalions of Colonel Julian N. Frisbie's 7th Marines started shoreward. An LCI [Landing Craft, Infantry] mounting multiple rocket launchers took position on the flank of the first wave bound for each of the two beaches and unleashed a barrage intended to keep the enemy pinned down after the cruisers and destroyers shifted their fire to avoid endangering the assault troops. At 0746, the LCVPs [Landing Craft, Vehicles and Personnel] of the first wave bound for Yellow Beach 1 grounded on a narrow strip of black sand that measured perhaps 500 yards from one flank to the other, and the leading elements of the 3d Battalion, commanded by Lieutenant Colonel William K. Williams, started inland. Two minutes later, Lieutenant Colonel John E. Weber's 1st Battalion, on the left of the other unit, emerged on Yellow Beach 2, separated from Yellow 1 by a thousand yards of jungle and embracing 700 yards of shoreline. Neither battalion encountered organized resistance. A smoke screen, which later drifted across the beaches and hampered the approach of later waves of landing craft, blinded the Japanese observers on Target Hill overlooking the beachhead, and no defenders manned the trenches and log-and-earth bunkers that might have raked the assault force with fire.
