Personal information
Adolf Piening began his navy career on the armored cruiser Deutschland, then spent a few years on torpedo boats and minesweepers before transferring in October 1940 to the U-boat arm. After the usual training he made one patrol on U-48 as Kommandantenschüler in June 1941. In August 1941 he took command of U-155. He was very successful with this boat and on 15 November, 1942 sank the British escort carrier HMS Avenger (13.875 tons).
In March 1944 he became the commander of the 7th Flotilla. On 30 April, 1945 he laid mines outside St. Nazaire with U-255. After the war he spent more than two years in Allied captivity. In 1956 the later Kapitän zur See Adolf Piening joined the Bundesmarine, serving for 13 years.
Piening is famous for the so-called Piening Route which he invented as a means to escape Allied aircraft in the Bay of Biscay.
