Cornelius,
I am not prone to flights of fancy, but if you reread some of your posts to Bobadilla, they do seem somewhat rude (at least, if they were directed at me, I would take offense, and I have a pretty thick skin).
While the Kriegsmarine may not have taken any treasure, many KM Officials got their share. Just like the Luftwaffe didn't really confiscate anything, but it's Commander (Hermann Goering) was the single largest holder of stolen war loot. He also used his authority to comandeer trains and motor vehicles to transport his loot, and troops of men to help hide it. Why is it so hard to believe that other commanders would have done the same?
I wanted to chime in here a little. As this is not my main area of interest, I don't know many of the details of the German U-Forces at the end of the war.
Even though Bremen was where the last of the German UBoats escaped, they still served as escape vessels for many high ranking Nazis. With the express (or implied) consent of Pope Pius XII, Catholic Priests assited some Nazis in escaping their impending doom. They helped them get through Italy, to other locations in Spain, Southern Italy, and Africa for further legs of the trip South America and the Middle East. Some of these Nazis were put on submarines for the trips.
Just My two cents.
best,
Mike
