Why Did The Schlieffen Plan Fail

Alfred von Schlieffen, the brains behind the Schlieffen Plan, wanted to make a war plan that would take into account the factors that it would have in the way. First of all, the plan was built around the fact that the war would be a two-front war between France and Russia. Also Austria-Hungary being their only ally that they can depend on. This plan plan was formed in 1905, so the plan lacked in industrial issues. For example, machine guns and other modern weapons that could create a big hole in the plan.

The original plan was to have most of the German troops march through Belgium and the Netherlands to Northern France. They knew this would cause Britain enter the war because that would be invading a neutral zone, being Belgium. Aside from the British part, the German troops were

When the Germans invaded Belgium, the French and Belgians would completely destroy the tracks as the were backinging up and retreating. This took away a lot of time that was needed to execute the plan because they had to lay the tracks back down. Also when invading Belgium it was
