How was the Schlieffen plan meant to work?
The Schlieffen plan was first acknowledged by Alfred Schlieffen in 1905. He had made it for a back up system so Germany would know what they would do if they had a war with France and Russia. But it was made to avoid the war on the two fronts and was supposed to wipe France out of the war.
In the following year, 1906, the plan had changed. When 1914 came around the war had started and German general Moltke decided to put the plan in action. The difference in the war was that 90% of Germany’s troops went through Holland, Belgium and Luxemburg to get into France without them noticing. After they achieved this the German army was supposed to encircle Paris and attack them from a different angle. The plan would avoid the French strong defence and the German front. If then the plan worked France would have been defeated and would not be in the war, so it would mean that Germany would not have a war on two fronts any longer.
