One silly question, - there are way too many links already. Yes, I am a lazy SoB.....
The LW had groups in Denmark and Norway at the time of the BoB. They tried an attack on the "flank", on the NE of England, presumably putting their money on that the British had no reserves left. The British however did (!)= and drove the LW back with some losses. It was not tried again.
So, did those units merge with those operating from France,or stay where they were?
BTW,if you're looking for numbers and such, I have an interesting game,- BOB strategy game from Talonsoft. Seems to have all numbers listed, and although not so playable, the outcomes in it are quite realistic. As LW, I won, as RAF,I also won

In both cases, I sucked all reserves to the front while my computer opponent did not!
