The Philippines became the centerpiece of General Douglas MacArthur’s promise to return. The Army was to lead, but when setbacks on Leyte bogged down operations, Marine aviation and artillery were rushed in. Within hours after their arrival, they were flying convoy cover, striking Japanese shipping, and dueling enemy aircraft. Despite crude airfields and poor coordination under Fifth Air Force control, Marines flew over 260 missions in their first few weeks.

By campaign’s end, Marine air had won Distinguished and Presidential Unit Citations, reshaped close air support doctrine, and proven indispensable. What began as reinforcement became central to victory, cementing Marine aviation’s legacy in modern warfare.

The 7th Marines landed on Peleliu under the command of Colonel Herman H. Hanneken. Veterans of Guadalcanal and Cape Gloucester, they now faced a new kind of hell. Their mission was to seize the island’s eastern shore, then pivot south to clear Japanese positions threatening the airfield.

Over weeks of unrelenting combat, they fought through blockhouses, mangrove swamps, and the notorious Bloody Nose Ridge, in brutal, close-quarters action. Acts of valor, like PFC Arthur J. Jackson’s Medal of Honor assault, stood against staggering casualties, disease, and exhaustion.

The episode follows the 7th Marines from their D-Day landing through the grinding fight inland, their eventual relief, and the debate that still surrounds whether Peleliu was worth the cost.

In this episode, we examine the 5th Marine Regiment’s role in the brutal Battle of Peleliu. As part of the 1st Marine Division, the 5th Marines were tasked with seizing the island’s strategically vital airfield. They advanced across open terrain under withering fire, securing the airfield despite intense Japanese resistance and extreme environmental conditions. By mid-October, after nearly a month of combat, the 5th Marines were physically spent and heavily depleted.
