Fighter pilots' guts

This sounds much better.
Yes to virtually all British, German and other authors the French Campaign ended on 3 June 1940 with the end of the Dunkerque evacuation. Most of their books don't even mention the Battle of France (5-24 June), they jump directly from Dk. to the BoB, clearly showing that the French are wholly unimportant and uninteresting, only the British part being interesting.
I don't think that ANY French pilot went to England before June 17. Certainly some aircraft landed there for various reasons but they were not joining the RAF (not yet). I have explained why not already. During the Dk. operation (Dynamo) one French unit was sent to England (GC II/8 equipped with about 20-25 Bloch 152s and having 25-30 pilots) and based at Lympne from 30 May to 5 June (for 5-6 days). This was ordered by French HQ and certainly government. I believe the reason was not so much the Dk. evacuation but the fact that they could better intervene over N. France from Lympne. (No warranty). GC II/8 shot down 1 Ju 88 on 1 June, nothing else (much ado...), and had no losses.
