What did the British call Germany's Operation "Steinbock" during World War II?

"Unternehmen Steinbock" (Operation "Steinbock") was the Luftwaffe's attempt to re-create what the British had nicknamed "the Blitz" during 1940 and 1941. So, during January to May 1944, the Luftwaffe carried out a series of attacks against southern England; "Steinbock" proved to be the last large-scale bombing campaign against England using conventional aircraft.

Militarily it was a dismal failure for the Germans. Although, three years on from the 1940/1 attacks, they now had much-improved night-bombing aircraft and improved electronic capabilities, they found themselves up against much better organised and better equipped defences. The Luftwaffe was never able to get the concentration of destructive power that, by that stage of the war, the Allied bomber forces were able to use against German cities. During "Steinbock" the Luftwaffe lost 329 of the 524 bombers that were eventually deployed (the wreckage of one is in the photo); the Royal Air Force lost just one aircraft in combat.

The British were adept at pinning nicknames on things they disliked or despised. The 1944 raids did cost civilian lives in England, but the deaths were on a much smaller scale compared with the 1940/1 campaign. For every 100 civilians that had been killed during "the Blitz" period, just three or four were killed in this new assault. So the British derisively referred to Operation "Steinbock" as "the Baby Blitz."
