 By this point , the Luftwaffe had subjected the UK to a major air campaign and caused an enormous amount of destruction and displacement of civilians . However , it failed to bring the UK to peace talks , nor had any obvious effect on economic output . At the end of May the Germans called off The Blitz , and from then on the UK would be subject to dramatically lower rates of bombing . How much of this was due to the effects of the night fighter force has been a matter of considerable debate among historians . The Germans were turning their attention eastward , and most of the Luftwaffe was sent to support these efforts . Even in May , the losses represent only 2 @.@ 4 % of the attacking force , a tiny number that was easily replaceable by the Luftwaffe .
