09.29 hrs, Bay of Biscay north of Corunna: four Mosquito aircraft (three from 307 Polish Sqdn RAF and one from 410 Sqdn RCAF) attacked a group of five outbound boats (U-68, U-155, U-159, U-415 and U-634). The leading Mosquito first strafed U-68 and then U-155, but its port engine stopped after being hit by flak and the aircraft was forced to return to base at Predannack, where it made a belly landing. A Mosquito piloted by F/O J. Pelka then made an attack run, but without firing, and the remaining aircraft were held off by an intense barrage of flak.Five of the crew of U-155 were wounded, two badly. The boat returned to base with U-68, whose doctor was transferred to treat the wounded on the way.

General notes on this boat

The crew of U-155 held their 25th meeting in September 1995! "Onboard" were the former Commander Oblt. Rudolph and the British pilot who bombed the boat in 1944 when she was returning to her base in Lorient.

The first commander of U-155, Adolf Piening, invented the so-called Piening-Route as a means to travel the Bay of Biscay.

15 Aug 1944. U-155 had the youngest U-boat Commander during the war, Leutnant zur See Ludwig-Ferdinand von Friedeburg. He took over the command of U-155 on 15 August 1944. He was 20 years and 3 months old at the time.

Schnorchel-fitted U-boat
This boat was fitted with a Schnorchel underwater-breathing apparatus and sailed equipped with it in August 1944 but it was of course installed prior to that date. Read more about the Schnorchel and see list of fitted boats.
