Digging In at Corregidor

In this episode, the 4th Marines move from Olongapo to Corregidor, just as the Japanese close in on Manila. What follows is a scramble to destroy U.S. naval bases, build up beach defenses, and dig in for a siege. We'll break down the geography of Corregidor, the fractured command structure, and the brutal reality of jungle survival. As Japanese air raids intensify and supplies dwindle, Marines rely on improvisation, grit, and foxholes to hold their ground. This is the start of one of the hardest chapters in Marine Corps history—the long, slow fight for the Philippines.
