because in German 'blitz' means lightning or very fast, and 'blitz krieg' effectifly translates in 'lightning campaign' or 'war like lightning'. when the Germans attacked the british it happened so...
Blitz is short for Blitzkrieg, German for lightning war
The Blitz is when the German Planes started very quickly bombing London Martha Peck
It was a series of bombing all over Britain
