On the show "Modern Marvels", they did a show about ice breakers. One of their comments was during WWII, the only vessel to capture a German surface vessel was a Coast Guard Ice Breaker.
So it appears we have at least five: A German Naval Auxillary, "Externsteine",
the German Weather ships "Munchen" and "Lauenburg" and the German supply
ship "Gedania". Plus the German trawler, "Krebs".
We're talking from 9/1/39 to 5/7/45 right? 'Cause if we are talking post war, the got the Prince Eugen after the war was over. But I guess that would be called repirations and maybe not a caputure.
Altmark wasnt captured. She was boarded, and searched, and the british seamen held in her released, after the norwegians claimed to have serched her and found nothing....
Altmark was in breach of international law, by housing POWs in a non-combatabt that was also in neutral waters.
The Nrowegians were no happy at being caught out as nazi collaborators. Mind you the British Destroyer that undertook the operation was also flouting Norwgian neutrality
