I googled whatshisname's PhD
http://www.plymouth.ac.uk/pages/view.asp?page=18359
on the grounds that it might make interesting reading. Some of the other offerings defy belief:
Development of an objective method of recording medieval wall plaster in Dorset churches
Still, as long as it's not my tax money....
Perhaps the point is, did the RAF win the BoB? Yes, because Goering didn't come back for more. So the role of the RN was secondary. But if the Luftwaffe had won, then what? Germany never had the capability to launch a large scale amphibious assault on the UK, even with complete air superiority. But why invade when Doenitz and a few more U-boats could have achieved victory by starvation?
I genuinely believe that Hitler had no idea what to do when Guderian reached the Channel in 7 days.
