For King and Kaiser The Making of a Prussian Army Officer. This was recommended to me as rather dry stuff. Actually I liked it. This is THE definitive work on the convoluted commissioning process. I have an article under the article tab. that explains this. The book looks and feels like a doctoral thesis. It is super exhaustively researched. Not much to say. No pictures just hard research. Not fir the weak but if you have an interest you will find a younger, less educated Prussian Officer who became part of the social elite. If you are steeped in the traditions of American commissioning you will find a wildly different technique. Almost eye opening but the system is so complex you get to slog through it.
