According to the linked German language source, forced repatriation of Germans was conducted with the American troop transports SS Marine Robin, SS Marine Jumper, and SS General Black from 1946 through 1947 on the order of the Nationalist Chinese government.
We searched the National Archives Catalog and located the file unit Germany: Repatriation of Germans from Japan and China in the series titled Security Classified General Correspondence Relating to Refugees, 1944 - 1954 (Record Group 165). There may be additional records related to German repatriation in Army, Merchant Marine, and Department of State records. However, we could not find any documents that have already been digitized and made available through the Catalog. Please contact the National Archives at College Park - Textual Reference (RDT2) via email at email@example.com for assistance with these records. If you are able to identify relevant records but are unable to visit our location in College Park, Maryland, they can assist you with purchasing digital copies.
We hope this information is helpful. Best of luck with your research!
Hi Mr. Gronemann;
Are you still working on the subject? My father was repatriated on the Marine Robin in 1946. What kind of information are you looking for?
