Featherstone (who sometimes used his middle initial and sometimes didn't) served in the Royal Armoured Corps in World War II before becoming a physiotherapist. He worked for Southampton Football Club and Hampshire County Cricket Club, writing books on sporting, dancing, and industrial injuries.
Later, he turned his attention to his childhood hobby of toy soldiers, writing dozens of books on the subject and becoming instrumental in the development of wargaming as a pasttime. He also wrote books on military history.
I've read several books by the prolific Donald Featherstone and this is my favorite so far. In it he does what he does best: write detailed and interesting reports on famous historical battles and offers advice on how to make them into wargames. Whether or not you follow his outlines for creating wargames. you should find this an interesting and lively read.
