Mr. Brown, I don't recall the title of the book, but it wasn't that one. Some of the things I DO remember, besides the need for/use of shotguns, are the skepticism of Allied commanders that these reservists (mainly mining engineers and suchlike trash) left behind could lead and that the Philippinos could be led. The pre-war Army was still very much a class-ridden organization, with a strong racial flavor. It took WWII to get us over that stuff. (And to be fair, the Phillipines IS a very different sort of "nation" than we were or are used to!).
