Did the Romanian Special Intelligence Service know about Operation Tidal Wave? (2)

In the article that I mentioned last time, Mihai Pelin remarks that one the most exciting books on this subject is James Dugan and Carroll Stewart's Ploesti: The Great Ground-Air Battle of 1 August 1943, an extremely well documented book when it comes to the U.S. raid in the Prahova Valley, but less accurate when depicting Romania's real situation at that time, especially concerning the U.S. POWs' fate in Romania, after the raid. The two authors of the book also interviewed architect Gerald K. Geerlings, who supervised the creation of sand table models and mock-up of the target, based on some... ten-year old photographs from the British Museum, lacking any information about the German and Romanian air defences in the Ploesti area. Although, in December 1939, the American photojournalist Margaret Bourke-White, accompanied by the journalist Walter Graebner, took extensive up-to-date photos of the Prahova Valley... Mihai Pelin suspects that architect Gerald K. Geerlings didn't tell Dugan and Stewart all he knew, and the two authors had no access to the Romanian military archives and they didn't know at all that the U.S. B-24's were expected by the Romanians on August 1st 1943. All the authors admit was that the Luftwaffe signals intelligence station in Athens might have warned the defences in the Prahova Valley, but the German Freya and Würzburg early warning radar stations of that time, installed in the Balkans, were unable to detect enemy targets below 1,000 m...

I also found on YouTube three videos entitled USSAF Training Film For Ploesti (part I, part II and part III): Now let's see what the Germans have done to arrange the defenses of this vital target. Happily for the Nazis, they have been out of range for us. The Nazis know that and so the defenses are nothing like as strong here as they are on the Western front. The fighter defenses of Ploesti are not strong, and the majority of the fighters will be flown by Romanian pilots who are thoroughly bored with the war. [...] Now the defenses of Ploesti may look formidable on paper, but, remember, they are manned by Romanians and Ploesti is practically a virgin target... Oh, man!... That hurt.
