First published in 1965, Jackboot traces the story of German militarism from the 17th century up to the date of print. The tone is decidedly German-biased, but you can generally spot where this is a problem - I found that wherever overly bombastic language was in use, this indicated some gargantuan exaggerations of fact and could be mentally toned down accordingly. Ince you allow for this, you actually do learn some useful information. However, you then tend to treat much of the historical detail - much of which is unsupported - as suspect. I am surprised that, in spite of its dubious historical credentials, this book has been reprinted as recently as 2000, but opinions will vary.
