Well, im willfully obtuse as many on this site probably correctly point out, but if the objective is to get the British to attack Germany, why did they drive them out of France? If they mean to Attack Britain, then attack Britain. But to my mind, attacking them to convince them to attack Germans... I dont get it. But thats just me.
As said, we let a piece of our sacred territory be occupied without much contest. Hell, we even sold Germany Heligoland before WW1, and that was a British territory as well. Churchill would give up any amount of territory up to Whitehall, as long as he was ideally placed to win.
They certainly did come do grips with the Brits in France. The RAF didn't fully commit to it to the chagrin of the French. Then the Brits left the continent so rudely at Dunkirk.
The Channel Islands comparison really isn't comparable since taking those led nowhere.
We know that a full Sealion had no chance, so this is a more plausible scenario to maintain the initiative and keep the pressure on.
Misnomer. The last Brits didnt leave France until the fall of France. The RAF tactical squadrons were still fighting till the end, and the 51st Highland Division got overrun at La Havre with their french counterparts IIRC. It was only French mythmakers that the British 'Abandoned' France that allowed this myth to take hold.
Yes, thats entirely my point. The channel islands led nowhere. You already said taking the Isle of Wight was designed not to lead anywhere because the British would attack. I submit, the British could happily have let the Germans starve whilst they sank all their amphibious shipping, and take all the rest after they had turned cannibal later. There was no reason for us to respond in such a situation. It would just be a smaller scale Stalingrad, with the water, which we dominated, the surrounding armies. It would achieve nothing.
Here are a couple of ideas that, sealion not working, would have achieved a lot more. Taking Gibraltar and Malta. I dont submit they were easy to take, or even likely to be taken. Just that they had more success than this, and their strategic outcome is far more clear.
