Thousands of pages of documentation describe atrocities carried out in both Eastern and Western Europe
Much of the original material was gathered when British and US intelligence services bugged a small number of prisoner of war camps near London and Washington DC during World War Two. For years the documents were kept under wraps by the intelligence services because the prisoner-of-war camp bugging program would have been regarded as illegal under international law – and, more importantly, because, during most of the Cold War, the US and Britain did not want to alert the Soviets to the fact that they had developed this intelligence gathering technique.
“All the relevant material was of course known to the British and American intelligence services during and after the war – and was in the public domain after its declassification in the US in the 1970s and the UK in 1996. However, prior to 2009, no use was ever made of the material to track down war criminals. If the direct evidence and the indirect leads contained in the material, had been used earlier by official war crime investigators, there is no doubt that a number of war criminals would have been arrested and brought to trial,” said London School of Economics historian, Professor Sönke Neitzel, co-author of Soldaten: On Fighting, Killing and Dying – a recently published book on the World War Two allied prisoner-of-war camp bugging operation.
A Channel 4 documentary – Spying on Hitler’s Army – on the secret bugging operation will be broadcast on Sunday evening.
In total some 3000 hours of clandestine recordings were made of German prisoners- of-war in UK and US PoW camps. Of those 3000 hours, up to 200 hours referred to war crimes. The US material was declassified in the 1970s, while the UK material was declassified in 1996. Professor Neitzel started his research into the material in 2001.
His first academic article was then published in 2004. In 2009 German government investigators heard that Professor Neitzel was carrying out academic research on the British and American documents and requested the material from him, which he then supplied. However, by that time, most of the suspects had died.
Because of the illegal nature of the bugging and the wish to keep it secret from the Soviets, the material was not used in the Nuremberg war crime trials.
Commenting on what appears to have been a proposal by the British Army’s department responsible for war crimes prosecutions (the Judge Advocate General’s Branch), MI19 (the Intelligence Service section responsible for the bugging operation) insisted that the existence of the transcripts could not be revealed in any way. This precluded their use in any war crime trials – and almost certainly greatly limited their use even in investigations.
A formerly top secret, and up till now unpublished, letter written by an MI19 lieutenant colonel on 16 November 1945, found by Professor Neitzel, in the National Archives at Kew, states that the organisation considers
The letter went on to say this was partly because “these methods” (ie. the bugging of German prisoners) “would presumably again feature largely in any future war” – ie against the Soviets.
What’s more, the letter pointed out that, at the time, those methods were “still being employed” inside prisoner-of-war camps by allied intelligence services outside the UK. The letter added that MI19 wanted to “avoid at any cost” anything that might disclose “the names of [German] PoWs who have been actively working for us”.
The MI19 lieutenant colonel also made clear the advanced nature of the British bugging techniques and equipment.
Professor Neitzel also believes that British war crimes prosecution authorities were not particularly interested in pursuing relatively junior war criminals even if their crimes were extensive and horrific.
Of the 10,000 prisoners who were secretly bugged, more than 300 were recorded as stating that they had participated in activities which were obviously war crimes or had witnessed such activities. That information in turn provided evidence that may have helped identify hundreds of other German soldiers who had committed war crimes, but had not been taken prisoner.
The transcripts reveal information about many types of war crime, including the mass-murder of Jews, the killing of PoW’s, the slaughter of civilians in anti-partisan operations and the rape of women in Nazi occupied territories in both Eastern and Western Europe. They provide evidence of war crimes which occurred in Russia, Lithuania, Latvia, Poland, Serbia, Belgium, France, Italy and Greece.
The suspects referred to in the bugging documentation – virtually all of whom have now died – include members of the Waffen SS and of the Wehrmacht – mostly from the lower ranks but including some more senior officers.
If the transcripts had been used for war crimes investigations at a much earlier stage, it’s likely that Lieutenant-General Heinrich Kittel (who died in 1969) may have faced prosecution as an alleged accessory because the documentation reveals that, when he was a colonel, he had witnessed serious war crimes – but apparently did nothing to stop them. General Dietrich von Choltitz, who died in 1966, might also have faced prosecution for his alleged role in the Holocaust, as revealed in the transcripts.
Other potential suspects died in the later 20th century and early 21st – including a Waffen SS non-commissioned officer called Fritz Swoboda who died in 2007 – just two years before the German investigators had access to the bugging operation transcripts.
