Research what it would have taken for an invasion force to invade England as it is quite interesting. To think; crossing the channel would be hard, there is the Navy and even sporadic attacks by the RAF. To be safe from the Navy, the landing scraft would need destroyers to protect them, but they can't travel anywhere near the landing-craft because they would be tipped over by the ships wake. So there would be no close sea-borne protection for the landing craft.
The time to cross the channel in this way was reportedly over 12 hours, and so picking the time of day would be tricky. Plus there is the weather to take into account, and the number of landing craft (and soldiers) needed to make an invasion this way, it really is not feasible in my opinion.
I am more of Zorin's opinion that English defeat would lie in submission, rather than all-out annhialation or invasion
Quite interesting really
