First came across this book in the 70s due to a copy bought by my late Father in the 50s -a graphic, sometimes harrowing read, particularly on the subject of his girlfriend,tortures he endured or witnessed,etc,later bought in the 80s a revised copy which corrected information not in the original due to lack of official records or the(then) need for secrecy the war only finished a few years earlier when work on book first started this book also a very interesting read-reccomended(both books)
