A standard schtick of films and children’s TV dramas in the sixties was the moment that a previously anonymous villain was revealed to be a former middle ranking Nazi official, seeking to act as a seed for the regeneration of the movement; and thenceforth filmed looking Aryan while standing on yachts in front of mountains with a 1,000 Year Reich stare accompanied almost invariably by the crescendo from Wagner’s Tanhauser overture.

This coincided with a lot of Nazi hunting stories sparked by the Eichmann trial in 1961, and the fact that no one had caught up with the Auschwitz “Angel of Death” Dr Josef Mengele, which gave the impression that the only surviving fragments of the old order – with the exception of Werner Von Braun, who was leading the US moon mission at the time and was therefore given a free pass – were leading lives of exiled obscurity in Argentina or Paraguay which, to be fair, some were. Mengele himself died when he drowned after suffering a stroke while swimming in Sao Paulo in 1979; having been given a passport in his own name by the West German Embassy in 1956 and actually visiting Europe using it in the late fifties.
This is a fairly extreme example of the way that former Nazis were reabsorbed into West German society in a wave of amnesia and omerta as the Cold War dug in. Von Braun, it turns out, was more the norm than Mengele or Eichemann. Though the Nuremburg Trials in 1945 -6 pronounced death sentences against 12 leading Nazis including Herman Goering and Joachim Von Ribbentrop, the number of former Nazis convicted of war crimes in the post war years up to 1958 was just 6,093. In the same period 729,176 had been amnestied. That looks like this.

Total Nazi Party membership in 1945 was 8 million, so most of them had no process at all.
Many others, not members of the Party, who committed war crimes were never held to account and simply melted back into their pre war roles. The unit of Hamburg policemen who formed an Einsatzgruppen execution squad (2) following on behind the Wehrmacht to march Jews, and sometimes Poles, out into the woods and shoot them in the back of the head, simply went back to Hamburg to direct traffic, follow up on petty crime and do all the usual things the police do. Only their commanding officer was held to account, executed after being extradited to Poland because of a massacre of Polish villagers. Their interviews in the early sixties were for historical purposes, and they were never held to account. Similarly, lower level former army, and even SS, officers provided the backbone of the Bundeswehr when it was reformed in 1955.
1 A belting piece of music which is well worth a listen if you’ve never heard it.
2 Documented in Ordinary Men. As grim a piece of reading as you’ll ever do. Its front cover illustration is of a squad of these men looking relaxed and grinning with local Jewish civilians kneeling in front of them with their hands up, was so abhorent that I couldn’t leave the book face up while I was reading it. It is chillingly echoed by some of the gloating social media posts by IDF soldiers in Gaza that show that fascism can infect anyone in the wrong circumstances.
