Dear Hans,

Sorry to pour cold water on your suggestion, but not a single one of the surrendered U-Boats in US Navy custody after May 1945 could have been involved.

They were all met their ends well to the east/north, as follows:

U-234 Sunk on 20 Nov 1947 by US S/M Greenfish off Cape Cod.

U-505 On display at the Chicago Museum of Science and Industry.

U-530 Sunk on 21 Nov 1947 by US S/M Toro off Cape Cod.

U-805 Scuttled off Cape Cod (at 42.32n/69.37w) on 8 February 1946

U-858 Sunk on 20 Nov 1947 by a US S/M off Cape Cod.

U-873 Sold for scrap in New York on 10 Mar 1948.

U-889 Sunk on 20 Nov 1947 by a US S/M off Cape Cod.

U-977 Sunk on 13 Nov 1946 by US S/M Atule off Cape Cod.

U-1105 Sunk on 18 Nov 1948 after demolition tests in Chesapeake Bay. Raised in July/August 1949, and sunk again on 21 December 1949 at the mouth of the Potomac River.

U-1228 Scuttled off Cape Cod (at 42.32n/69.37w) on 5 February 1946

U-1406 Sold for scrap in New York on 18 May 1948.

U-2513 Sunk on 7 Oct 1951 off Key West by the destroyer USS Robert A Owens.

U-3008 Sold for scrap to Loudes Iron & Metal Co, Puerto Rico on 15 September 1955. Loudes took possession of it on 17 January 1956, and it was subsequently broken up in Puerto Rico in 1956.

Hope that helps.
