On January 6, 1949, two starving Japanese machine gunners walked out of the caves on Iwo Jima and surrendered to American airmen who had no idea they were there. The war had been over for more than three years. They're where this episode ends, and they're the reason it exists. Before them came the battle. This one goes deep into the fight for a stinking scrap of volcanic ash 650 miles south of Tokyo, and the general who turned it into one of the worst killing grounds of the Pacific war. 

Tadamichi Kuribayashi knew Japan couldn't win, so he buried his garrison 16 miles deep in the rock and ordered his men to make the island cost more than it was worth. It worked. American casualties came out higher than the entire Japanese force defending the place, the only major Pacific battle where that ever happened. We walk through the ash-trap landing, the flag on Mount Suribachi and what the famous photograph left out, the blowtorch-and-corkscrew cave fighting up north, and the roughly 3,000 Japanese soldiers still alive inside the island the day it was declared secure.

Then the episode follows the men who never stopped. Two Navy machine gunners held out in the tunnels until 1949. A captain named Sakae Oba ran a guerrilla campaign on Saipan until his own chain of command ordered him to quit. A group of stranded sailors on the island of Anatahan came apart into something far darker over six years cut off from the world. Sergeant Shoichi Yokoi hid in the jungle on Guam for 28 years, suspecting the war was over and staying hidden anyway.

Lieutenant Hiroo Onoda fought his own private war on Lubang in the Philippines until 1974 and killed around 30 local people who had nothing to do with it. And Teruo Nakamura, the last holdout of all, walked out the same year and got almost none of the welcome Onoda did, for reasons that say a lot about the empire he'd served. It comes down to what an institution can put inside a young man's head, and how long that programming keeps running after everything that built it is gone.

 There are still more than 10,000 Japanese soldiers sealed inside Iwo Jima. Most of them are never coming home.
