Image:\u00a0U.S. Navy<\/figcaption><\/figure>\n<p>Another typically grandiose element of MacArthur\u2019s strategy was to include the pivotal Japanese air and sea base at Rabaul as an objective for the operation, now code-named Dexterity. Even members of his own staff sided with the Marines objecting to that as a bridge too far. Since the Japanese had landed at Rabaul on the northeast point of New Britain in 1942, they had developed a sprawling base with port facilities and airfields manned by a formidable number of defenders. Reluctantly, MacArthur agreed that Rabaul should be bypassed and pummeled continuously by air strikes rather than subject to a ground attack. The focus of Operation Dexterity was narrowed to western New Britain and the seizure of the all-important Japanese airstrip at Cape Gloucester. Get that done, and MacArthur\u2019s flanks would be safe from enemy airstrikes as he fought on New Guinea and drove toward the Philippines.<\/p>\n<figure class=\"wp-block-image size-full flush\"><picture loading=\"lazy\" decoding=\"async\" class=\"wp-image-60275\"><source type=\"image\/webp\" srcset=\"https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2025\/02\/Major-General-William-H-Rupertus-coammder-at-Cape-Gloucester.jpg.webp 1115w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2025\/02\/Major-General-William-H-Rupertus-coammder-at-Cape-Gloucester-637x800.jpg.webp 637w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2025\/02\/Major-General-William-H-Rupertus-coammder-at-Cape-Gloucester-319x400.jpg.webp 319w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2025\/02\/Major-General-William-H-Rupertus-coammder-at-Cape-Gloucester-768x964.jpg.webp 768w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2025\/02\/Major-General-William-H-Rupertus-coammder-at-Cape-Gloucester-600x753.jpg.webp 600w\" sizes=\"auto, (max-width: 1115px) 100vw, 1115px\"\/><img loading=\"lazy\" decoding=\"async\" width=\"1115\" height=\"1400\" src=\"https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2025\/02\/Major-General-William-H-Rupertus-coammder-at-Cape-Gloucester.jpg\" alt=\"Major General William H Rupertus coammder at Cape Gloucester\" srcset=\"https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2025\/02\/Major-General-William-H-Rupertus-coammder-at-Cape-Gloucester.jpg 1115w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2025\/02\/Major-General-William-H-Rupertus-coammder-at-Cape-Gloucester-637x800.jpg 637w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2025\/02\/Major-General-William-H-Rupertus-coammder-at-Cape-Gloucester-319x400.jpg 319w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2025\/02\/Major-General-William-H-Rupertus-coammder-at-Cape-Gloucester-768x964.jpg 768w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2025\/02\/Major-General-William-H-Rupertus-coammder-at-Cape-Gloucester-600x753.jpg 600w\" sizes=\"auto, (max-width: 1115px) 100vw, 1115px\"\/>\n<\/picture><figcaption class=\"wp-element-caption\">Maj.

Much of his fighting strength was tied up defending in New Guinea or the northern Solomons.<\/p>\n<figure class=\"wp-block-image size-full\"><picture loading=\"lazy\" decoding=\"async\" class=\"wp-image-60278\"><source type=\"image\/webp\" srcset=\"https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2025\/02\/US-Marines-move-through-thick-jungle-to-engage-the-Japanese.jpg.webp 1400w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2025\/02\/US-Marines-move-through-thick-jungle-to-engage-the-Japanese-800x643.jpg.webp 800w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2025\/02\/US-Marines-move-through-thick-jungle-to-engage-the-Japanese-400x321.jpg.webp 400w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2025\/02\/US-Marines-move-through-thick-jungle-to-engage-the-Japanese-768x617.jpg.webp 768w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2025\/02\/US-Marines-move-through-thick-jungle-to-engage-the-Japanese-600x482.jpg.webp 600w\" sizes=\"auto, (max-width: 1400px) 100vw, 1400px\"\/><img loading=\"lazy\" decoding=\"async\" width=\"1400\" height=\"1125\" src=\"https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2025\/02\/US-Marines-move-through-thick-jungle-to-engage-the-Japanese.jpg\" alt=\"US Marines move through thick jungle to engage the Japanese\" srcset=\"https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2025\/02\/US-Marines-move-through-thick-jungle-to-engage-the-Japanese.jpg 1400w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2025\/02\/US-Marines-move-through-thick-jungle-to-engage-the-Japanese-800x643.jpg 800w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2025\/02\/US-Marines-move-through-thick-jungle-to-engage-the-Japanese-400x321.jpg 400w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2025\/02\/US-Marines-move-through-thick-jungle-to-engage-the-Japanese-768x617.jpg 768w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2025\/02\/US-Marines-move-through-thick-jungle-to-engage-the-Japanese-600x482.jpg 600w\" sizes=\"auto, (max-width: 1400px) 100vw, 1400px\"\/>\n<\/picture><figcaption class=\"wp-element-caption\">The U.S. Marines moved through mud and thick jungle to engage the Japanese.

Army Air Corps B-25 bombers headed for New Britain on a bombing run in support of the Marines. The Japanese had similar plans and sent their own bombers and fighters from Rabaul to support defenders on Cape Gloucester. At some point over the landing sites, the two air forces tangled. Nervous Navy gunners aboard ships in the beachhead area, blazed away at the Japanese aviators with an intense curtain of AA fire. Unfortunately, the gunners aboard LSTs out in the bay got confused in the melee and shot down several American planes. The Japanese were on the losing end of the air battle with most of the planes they sent shot down, but they did some damage. They managed to seriously damage a U.S. destroyer that later sank.<\/p>\n<figure class=\"wp-block-image size-full\"><picture loading=\"lazy\" decoding=\"async\" class=\"wp-image-60287\"><source type=\"image\/webp\" srcset=\"https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2025\/02\/Japanese-bombers-are-engaged-by-anti-aircraft-guns-during-the-Battle-of-Cape-Gloucester.jpg.webp 1400w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2025\/02\/Japanese-bombers-are-engaged-by-anti-aircraft-guns-during-the-Battle-of-Cape-Gloucester-800x636.jpg.webp 800w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2025\/02\/Japanese-bombers-are-engaged-by-anti-aircraft-guns-during-the-Battle-of-Cape-Gloucester-400x318.jpg.webp 400w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2025\/02\/Japanese-bombers-are-engaged-by-anti-aircraft-guns-during-the-Battle-of-Cape-Gloucester-768x611.jpg.webp 768w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2025\/02\/Japanese-bombers-are-engaged-by-anti-aircraft-guns-during-the-Battle-of-Cape-Gloucester-600x477.jpg.webp 600w\" sizes=\"auto, (max-width: 1400px) 100vw, 1400px\"\/><img loading=\"lazy\" decoding=\"async\" width=\"1400\" height=\"1113\" src=\"https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2025\/02\/Japanese-bombers-are-engaged-by-anti-aircraft-guns-during-the-Battle-of-Cape-Gloucester.jpg\" alt=\"Japanese bombers are engaged by anti-aircraft guns during the Battle of Cape Gloucester\" srcset=\"https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2025\/02\/Japanese-bombers-are-engaged-by-anti-aircraft-guns-during-the-Battle-of-Cape-Gloucester.jpg 1400w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2025\/02\/Japanese-bombers-are-engaged-by-anti-aircraft-guns-during-the-Battle-of-Cape-Gloucester-800x636.jpg 800w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2025\/02\/Japanese-bombers-are-engaged-by-anti-aircraft-guns-during-the-Battle-of-Cape-Gloucester-400x318.jpg 400w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2025\/02\/Japanese-bombers-are-engaged-by-anti-aircraft-guns-during-the-Battle-of-Cape-Gloucester-768x611.jpg 768w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2025\/02\/Japanese-bombers-are-engaged-by-anti-aircraft-guns-during-the-Battle-of-Cape-Gloucester-600x477.jpg 600w\" sizes=\"auto, (max-width: 1400px) 100vw, 1400px\"\/>\n<\/picture><figcaption class=\"wp-element-caption\">During the fighting on Cape Gloucester, Japanese bombers attempted to sneak in under the cover of night.

When Rupertus got wind of this, he decided to advance the schedule and brought the 5<sup>th<\/sup>\u00a0Marines ashore without further delay.<\/p>\n<figure class=\"wp-block-image size-full\"><picture loading=\"lazy\" decoding=\"async\" class=\"wp-image-60292\"><source type=\"image\/webp\" srcset=\"https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2025\/02\/US-Marines-man-a-75mm-M116-howitzer-during-the-Battle-for-Cape-Gloucester.jpg.webp 1400w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2025\/02\/US-Marines-man-a-75mm-M116-howitzer-during-the-Battle-for-Cape-Gloucester-800x639.jpg.webp 800w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2025\/02\/US-Marines-man-a-75mm-M116-howitzer-during-the-Battle-for-Cape-Gloucester-400x320.jpg.webp 400w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2025\/02\/US-Marines-man-a-75mm-M116-howitzer-during-the-Battle-for-Cape-Gloucester-768x614.jpg.webp 768w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2025\/02\/US-Marines-man-a-75mm-M116-howitzer-during-the-Battle-for-Cape-Gloucester-600x480.jpg.webp 600w\" sizes=\"auto, (max-width: 1400px) 100vw, 1400px\"\/><img loading=\"lazy\" decoding=\"async\" width=\"1400\" height=\"1119\" src=\"https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2025\/02\/US-Marines-man-a-75mm-M116-howitzer-during-the-Battle-for-Cape-Gloucester.jpg\" alt=\"US Marines man a 75mm M116 howitzer during the Battle for Cape Gloucester\" srcset=\"https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2025\/02\/US-Marines-man-a-75mm-M116-howitzer-during-the-Battle-for-Cape-Gloucester.jpg 1400w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2025\/02\/US-Marines-man-a-75mm-M116-howitzer-during-the-Battle-for-Cape-Gloucester-800x639.jpg 800w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2025\/02\/US-Marines-man-a-75mm-M116-howitzer-during-the-Battle-for-Cape-Gloucester-400x320.jpg 400w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2025\/02\/US-Marines-man-a-75mm-M116-howitzer-during-the-Battle-for-Cape-Gloucester-768x614.jpg 768w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2025\/02\/US-Marines-man-a-75mm-M116-howitzer-during-the-Battle-for-Cape-Gloucester-600x480.jpg 600w\" sizes=\"auto, (max-width: 1400px) 100vw, 1400px\"\/>\n<\/picture><figcaption class=\"wp-element-caption\">Marines pass ammunition to the M116 howitzer crew during a fire mission on Cape Gloucester.

Those fights ranged from small meeting engagements to full-blown, battalion-level attacks, but it was clear that the Japanese in the Cape Gloucester area of New Britain had shot their bolt. Japanese General Matsuda issued orders for his remaining 1,100 troops to fall back toward Rabaul. They were chased by long-range Marine artillery that had come ashore during the preceding days as well as Marines sent by Rupertus to try and cut off their retreat.<\/p>\n<figure class=\"wp-block-image size-full\"><picture loading=\"lazy\" decoding=\"async\" class=\"wp-image-60300\"><source type=\"image\/webp\" srcset=\"https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2025\/02\/combined-arms-action-on-Cape-Gloucester-M4-Sherman-tank-and-Marine-riflemen.jpg.webp 1400w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2025\/02\/combined-arms-action-on-Cape-Gloucester-M4-Sherman-tank-and-Marine-riflemen-800x611.jpg.webp 800w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2025\/02\/combined-arms-action-on-Cape-Gloucester-M4-Sherman-tank-and-Marine-riflemen-400x306.jpg.webp 400w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2025\/02\/combined-arms-action-on-Cape-Gloucester-M4-Sherman-tank-and-Marine-riflemen-768x587.jpg.webp 768w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2025\/02\/combined-arms-action-on-Cape-Gloucester-M4-Sherman-tank-and-Marine-riflemen-600x459.jpg.webp 600w\" sizes=\"auto, (max-width: 1400px) 100vw, 1400px\"\/><img loading=\"lazy\" decoding=\"async\" width=\"1400\" height=\"1070\" src=\"https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2025\/02\/combined-arms-action-on-Cape-Gloucester-M4-Sherman-tank-and-Marine-riflemen.jpg\" alt=\"combined arms action on Cape Gloucester M4 Sherman tank and Marine riflemen\" srcset=\"https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2025\/02\/combined-arms-action-on-Cape-Gloucester-M4-Sherman-tank-and-Marine-riflemen.jpg 1400w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2025\/02\/combined-arms-action-on-Cape-Gloucester-M4-Sherman-tank-and-Marine-riflemen-800x611.jpg 800w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2025\/02\/combined-arms-action-on-Cape-Gloucester-M4-Sherman-tank-and-Marine-riflemen-400x306.jpg 400w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2025\/02\/combined-arms-action-on-Cape-Gloucester-M4-Sherman-tank-and-Marine-riflemen-768x587.jpg 768w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2025\/02\/combined-arms-action-on-Cape-Gloucester-M4-Sherman-tank-and-Marine-riflemen-600x459.jpg 600w\" sizes=\"auto, (max-width: 1400px) 100vw, 1400px\"\/>\n<\/picture><figcaption class=\"wp-element-caption\">Close to Cape Gloucester\u2019s airport, this M4 Sherman tank just fired into a Japanese pillbox and is ready to advance with the infantrymen.

They also emphasized the importance of Engineers and Shore Party support, and demonstrated effective ways to use those assets in adverse weather and terrain conditions.<\/p>\n<figure class=\"wp-block-image size-full\"><picture loading=\"lazy\" decoding=\"async\" class=\"wp-image-60302\"><source type=\"image\/webp\" srcset=\"https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2025\/02\/Cape-Gloucester-airport-secured-by-US-Marines.jpg.webp 1400w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2025\/02\/Cape-Gloucester-airport-secured-by-US-Marines-800x639.jpg.webp 800w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2025\/02\/Cape-Gloucester-airport-secured-by-US-Marines-400x319.jpg.webp 400w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2025\/02\/Cape-Gloucester-airport-secured-by-US-Marines-768x613.jpg.webp 768w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2025\/02\/Cape-Gloucester-airport-secured-by-US-Marines-600x479.jpg.webp 600w\" sizes=\"auto, (max-width: 1400px) 100vw, 1400px\"\/><img loading=\"lazy\" decoding=\"async\" width=\"1400\" height=\"1118\" src=\"https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2025\/02\/Cape-Gloucester-airport-secured-by-US-Marines.jpg\" alt=\"Cape Gloucester airport secured by US Marines\" srcset=\"https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2025\/02\/Cape-Gloucester-airport-secured-by-US-Marines.jpg 1400w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2025\/02\/Cape-Gloucester-airport-secured-by-US-Marines-800x639.jpg 800w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2025\/02\/Cape-Gloucester-airport-secured-by-US-Marines-400x319.jpg 400w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2025\/02\/Cape-Gloucester-airport-secured-by-US-Marines-768x613.jpg 768w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2025\/02\/Cape-Gloucester-airport-secured-by-US-Marines-600x479.jpg 600w\" sizes=\"auto, (max-width: 1400px) 100vw, 1400px\"\/>\n<\/picture><figcaption class=\"wp-element-caption\">Securing this Japanese airbase was one of the main objectives of the Battle of Cape Gloucester.
