Good posts parsival, I have read similar before as I see it the LW were accustomed to fighting Bi Planes in the main while against the UK they had an opposing force equal in quality and numbers to their own(or almost) when they attacked an airfield there wasn't a mechanised division rumbling over the horizon. Having crossed the channel a good few times I cant get my head around someone mistaking it for a river, especially a senior military commander. There have been times when the weather has been so bad IN THE HARBOUR that boarding a car on a ferry in the port wasnt possible and at other times I was stuck in the channel for 4 hours with fog, all around Calais.
