Bomber Command did attack German airfields located in Holland and Denmark during August 1940. Two attacks were of note, in one a RAF squadron managed to destroy 9 He-111s on the ground with no losses, on the other almost a complete Blenheim squadron was wiped out before they got to the target (the one aircraft to get back aborted en route and the pilot was courts marshaled). Attacking the German Airfields in the Pas de Calais was a non starter. There were a lot of them, defended by a large amount of light flak and a large number of Bf-109s, of which 20% were held back for base defence at any one time as a result of the Bomber Command efforts, which did in a small part reduce to 109 threat to Fighter Command.
Fighter Command did do Fighter Sweeps over France in 1941/2 while Leigh Mallory was in charge of 11 group with big wing tactics and the net result was a German victory. Park or Saul would not have made that mistake.
