Hi Robbie, I can answer that 2nd question for you now
He and his crew were one of at least 10 Uboats that were stationed in Singapore (Panang) They were under the command of Kapitan zur See Wilhelm Dommes. The commander of U 181 at that time was Kapitan zur See Kurt Freiwald. Yopu might recognize the mans name that he took it over from who was Korvettenkapitan Wolfgang Luth.
ANyway, as of sometime in 1944, U 181 was transferred to operate in the areas near Singapore. When the war ended (with the Germans surrender of May the 8th) that meant that these men too had to lay down their arms.
The Japanese had always been cordial to the Germans but, when Germany surrendered, the Japanese though still treated them fairly respectively but, had to take them into custody supposedly for their own protection.
They were held in Japanese detention till I think November 1945 some weeks after Japan too had surrendered. When the war ended for the Germans, they had to give their Uboats over to the Japanese. The Japanese renamed the U 181 to I-501 I think?
If memory serves me well, these men were handed over to the British Authorities. Several of the U 181 crew stayed on and lived in England, Scotland and Wales. About 2 or so months ago, I was contacted by the daughter and grandchildren of one of the former U 181 crew who happened to still be living in Wales. I was able to reunite him with about 7 other U 181 vets.
The only living officer of U 181 Dietrich Hille, worked and lived in England many many years. He worked with the British Govt on Navy projects and Engineering projects.
I will be more than glad to ask Karl what John Wayne films he remembered seeing if he does not post them here first.
Take care and best regards--TRK.
