The author proved throughout the book that he has a very limited understanding of the world around him. He can never see the relation between actions and result (proudly states he was a member of a secret organisation planning sedition, pages later considers unfair that he is arrested by the state) and is borderline comical as he genuinely believes that the nazis are promoting him due to his wonderful activities. He just does not get it that he is simply a useful idiot that is assigned tasks that nobody wants to do (like spying on his comrades).
That being said, the book is filled cover to cover with... revisionist statements:
" the Romanians are the foreigners; they don't belong here. The Hungarians and Saxons, now minorities, are the rightful owners, or if you like, inhabitants." - page 6, talking about the present day Romania
... Nazi apologism:
"Adolf may be a nutcase, but he is right in many things." - Page 105
"I thought what a pity that the world could not have seen and heard us as we really were." -- page 28, about being a nazi.
... Racism:
"The area was now being built into one of the largest SS Truppenübungsplatz (training camp), labor being supplied by predominantly Jewish KZ (Konzentrazions- Lager— concentration camp) inmates. The only crime these unfortunate people ever committed was their accident of birth." -- page 25
"This discrimination was understandable as of all the Eastern European ethnic Germans, the Transylvanian Saxons were the only ones who were in every respect comparable with the Reichsdeutsche." -- page 99
"God, to think that the Western Powers had helped these apes to win the war." -- page 144, about the Russians
.. And of course, the occasional atrocity, fully justified in the author's opinion:
"Now and then we did, however, surprise large gatherings of partisans, and those of them who did not die fighting were either shot or, more often, hanged. The so- called free world made a lot of noise about these killings, but according to international law, which the Allies were very keen on bringing up when it suited them, these armed civilians were murderers to be hanged, at least as far as we were concerned." --page 32
"Next morning at the first opportunity, we untied their hands and sent them scampering across a large, apparently deserted square toward the Russians. Predictably, the Russians pounced like spiders in their webs and grabbed our two Commie sympathizers. Within a couple of minutes the only too- well- known tortured shrieks of agony told us the Russians lived up to our expectations." -- page 125
"We sent the Hungarians off, took possession of the Ivans, and marched them in small, terrified groups to the nearest site of Russian butchery where we shot each one through the head in blind reprisal." -- page 96
Besides this, the book has very little historical or literary value. The information is inaccurate, obviously embellished (the author has a thing about losing all his teeth, which he does at least 5 times through the book) and the writing style is plain at best.
