As with all Osprey titles this book is not meant to be anything more than a general overview and a jumping off point for greater research. On that basis I recommend it.
However, there is one part of the book that I must criticize. On page 24 there is a reference to St. Ignatius Loyola and the Jesuits. The author posits that Himmler took his organizational model from the Jesuits and that Hitler often referred to him as "my Ignatius Loyola".
Of course none of these remarks are place in any kind of context and the reader is left with the impression that Hitler, Himmler and the SS were buddy-buddy with the Jesuits.
That the editors allowed this to go to print I find appalling and insulting. The Waffen SS had about as much in common with the Jesuits as they did with the Salvation Army.
It is a well known F-A-C-T that both Hitler and Himmler especially hated both Christianity and the Catholic Church. Nazi ideology, especially as practiced by the Waffen SS, was daimetrically opposed to everything the Jesuits stood for and for the author to leave his reader with any other impression is a gross error and monumental misrepresentation.
This flaw almost makes the book not worth buying.
