Stephan Bungay has pointed out the low military value of shooting down DAF fighters, rather than the bombers that, by mid-1942, were having a highly damaging effect on Axis ground units and convoy routes. Referring to 1 September 1942, Bungay points out that even if Marseille shot down 15 of the 17 he claimed that day, "the rest of the 100 or so German fighter pilots between them only got five. The British lost no bombers at all... During this period the DAF lost only a few bombers, but all fell to anti-aircraft defences and evidence shows that Rommel was forced onto the defensive because of the losses inflicted by bombers.
