Churchill's Dream
Admiral Fisher's plan for an amphibious invasion of Pomerania in 1915/1916 to march on Berlin and end the war. He managed to get as far as three shallow-draught 32-knot cruisers (Courageous, Glorious, Furious) for fire support. Churchill went for Gallipoli instead.
Let's consider Churchill's Dream instead, his proposal to take the islands of Borkum and Sylt by an amphibious landing and to construct an artificial island with fortified caissons on Horn Reef. If nothing else, it might force the High Seas Fleet out into waters controlled by the Royal Navy. A landing on Heligoland might also be needed to safeguard the rear and provide a support base...
