I visited the Museum of the Pacific War in Fredericksburg, TX this week and samples of the Japanese war propaganda found therein aren't all that different from what we see here. BTW, this is a world-class museum since Admiral Chester Nimitz, Commander of the Pacific Theater after Pearl Harbor, was born there. Highly recommended for the war buff and/or historian.
This sounds like a perfectly terrifying adventure, and history is full of them. And now I have to read more to learn about how they handled the lack of water.
