There’s a number of books on the 442nd, can’t remember which one I read but it had really funny quotes throughout the book, sometimes anonymous that related to the text. There was also a movie made I think in the 60s that I heard was good but I’m thinking a remake might prove to be really successful.
Living in Hawaii you realize how tight island life is. Everyone knows each other - would have been more so then. You would be hard pressed to find a more cohesive group and I think that was one of the keys to their success. Most had never been in snow - or even cold. They were used to eating fish and pig and lots of rice. They were small compared to mainlanders and as a result the military didn’t have clothes that fit them. Some of them rarely wore shoes! One guy had a size 4EEE - almost a hoof. Just the immense physical and psychological shock of ending up in Europe in brutal conditions would have been enough, but they had to fight for their lives on top of that. Just an amazing story. I still see a few members from time to time, usually at fundraisers.
Also worth reading is the battle of Niihau.
