I just read a ghastly article on the horrors of the Battle of the Somme and it got me thinking — why didn’t Britain mount an aquatic invasion of Germany in WWI? Britain had already decimated the German fleet at Jutland, they knew German forces were spread thin across the fronts, and the hopelessness of trench-based offensive were already quite obvious. Was there anything stopping the British / French from landing ships behind enemy lines and attacking from behind?
