Okinawa: The Last Barrier

By 1945, Okinawa stood as the last barrier before the homeland, vital to both Japanese defense and American invasion plans. The Japanese abandoned beach defenses and instead transformed ridges, caves, and limestone plateaus into layered strongholds, preparing to bleed the invaders inland. The United States assembled the Tenth Army to launch the largest amphibious assault of the Pacific. The episode closes on L-Day, April 1, 1945, as four divisions landed across Hagushi beaches, beginning the climactic battle that would test Okinawa's terrain, its people, and both armies to the limit.
