The first XXIII, U-2321, was launched from Deutsche Werft in Hamburg on 17 April, 1944, she was one of the 6 XXIII's that went on operational patrol around the British Isles in early 1945. U-4712 was the last one launched, on April 19, 1945.
The first XXIII to go out on patrol was U-2324 on 29 Jan 1945. The U-2336 under the command of Kptlt. Klusmeier sank the last ships sunk in WWII on May 7 when he sank two British freighters inside the Firth of Forth.
None of the 6 operational XXIII's (U-2321, U-2322, U-2324, U-2326, U-2329 and U-2336) was sunk by the allies during Jan - May 1945. 3 of these boats sank 4 ships for a total of 7,392 tons.
