What was the German submarine offensive called called operation drumbeat in 1942?
as this was an offensive, something martial-sounding and up-beat ( excuse the term) was appropriate. Probably the German phrase was Paukenschlag- a roll on the drums and this implies heavy bass drums used by military bands and parades- again a martial connotation. Pauker is a heavy drummer ( an occupational noun) Schlag- hit , beat, etc.
