He might have been speaking of the V-1 Buzz Bombs (or the V-2's) which were unguided flying bombs launched on innocent populations by the Nazis "between 13 June 1944 and 29 March 1945."
Compare that to the German losses in the Battle for Berlin April - May 1945.Almost 30,000 V-1s were made. Approximately 10,000 were fired at England; 2,419 reached London, killing about 6,184 people and injuring 17,981. The greatest density of hits were received by Croydon, on the SE fringe of London.
