Specific use of blitz. The Blitz was in truth not a blitzkrieg, which is a rapid ground offensive based on superior tank forces. However, the word was current at the time for the successful German campaigns in Poland and France, and was transferred to the attacks on Britain, perhaps by association of Blitz (“lightning”) with the bombings.
Often used with 'on' to indicate the target of the effort (e.g., 'a blitz on crime').
