Ces péripéties ne semblent pas pouvoir expliquer en effet un nez retroussé pour l'U48 (si c'est lui) ...

attaque par grenadage :

attaque par grenadage :
22 Mar 1941
The boat was depth charged by British destroyers and suffered slight damage.
la seule tentative d'éperonnage (mais infructueuse ?) :
29 Mar 1941
The boat was fired on by several merchant ships while attacking the unescorted convoy HX 115 south of Iceland, moving through the columns at night on the surface, and at least one of the freighters, the British steam merchant Oakworth made an attempt to ram her. However, U-48 was undamaged and even managed to escape without being attacked when the escorts eventually arrived in the morning.
