Of permanent worth and an important book and an interesting history of the military development of the world powers from the middle ages to the present. The author draws a fine line between the military way and the militaristic way; the former scientific, the latter traditional. The author is a German and an historian, with a practical experience of four and a half years in the army. His appreciation of the implications of his profession as historian forced him out of Nazi Germany... The book is fully annotated. Will be a valuable addition to reference shelves and of interest to students of world affairs and general history.
