Jochen Mohr
The lucky Kapitänleutnant 'Jochen' Mohr after a patrol.

'Jochen' Mohr was one of a handful of U-boat officers who spent their entire U-boat careers on a single boat. He completed his first three patrols under the command of Kapitänleutnant Georg-Wilhelm Schulz.

Mohr achieved great success against enemy warships. On his first patrol as commander, in November 1941, he sank the British light cruiser HMS Dunedin and in 1942 he sank the French corvette Mimosa. Especially remarkable was the night of 12 May, 1942, when U-124 sank four ships with a total of 21,784 tons from convoy ONS-92.

A doggerel composed by Mohr on his way back from the US East Coast:

The moon night is as black as ink
Off Hatteras the tankers sink
While sadly Roosevelt counts the score
some fifty thousand tons. Mohr

Mohr was killed when his boat was sunk with all hands on 2 April, 1943 west of Oporto, Portugal, by the British corvette HMS Stonecrop and the sloop HMS Black Swan (Niestlé, 1998).
