> - Field Marshal Alfred von Schlieffen writes a plan which becomes the sacred text of how the German army is to conduct a two front war against France and Russia. One of the critical parts of that plan is marching a truly massive German army through neutral Belgium. > - When France Germany and Russia go to war Germany following the Schlieffen plan marches through Belgium triggering UK involvement in the war. Neither of these points are true. Schlieffen produced several different war plans for different potential scenarios and in WW1 Germany wound up following a very heavily modified version of one of those plans. While Britain officially gave the violation of Belgian neutrality as its reason for entering the war, and it certainly swayed public opinion in favor of the conflict, they had signed a treaty with France in 1911 pledging military support in the event of a German invasion regardless; and more generally had been in an increasingly antagonistic relationship with Germany for years. Perhaps had Schlieffen not been so obsessed with Cannae he would have made different recomendations, but the fact is that the rest of the German general staff generally agreed with the logic behind those recomendations. Then when their plans were put into action, they were largely vindicated as the invasion through Belgium did allow Germany to gain a massive advantage in the opening weeks of the war and sieze territory from which it would take years and millions of men to dislodge them. Indeed the main issue was that the plan assumed Russia would be slow to mobilize, giving the German army time to defeat France before they would have to reposition forces to the eastern front, but to everyone's surprise Russia instead mobilized quickly. A generation later, when the men who were boots on the ground at the time now led the German military, and had decades to study the previous conflict, they decided on attempting a plan that was broadly similar and again had great initial success. It's possible that Germany employs a totally different strategy in WW1 if Schlieffen isn't obsessed with Cannae, but there's no real evidence that they would.
