British intelligence sent false reports via their Double-Cross System implying that the rockets were over-shooting their London target by . This tactic worked; more than half of the V-2s aimed at London landed outside the London Civil Defence Region. Most landed on less-heavily populated areas in Kent due to erroneous recalibration. For the remainder of the war, British intelligence kept up the ruse by repeatedly sending bogus reports implying that the rockets were now striking the British capital with heavy loss of life.
