World War I The Schlieffen Plan was the German army’s for war against France and Russia. It was created by German Chief of Staff Alfred Von Schlieffen in 1903. The countries reacted in different ways. The Belgium fought hard against the Germans and delayed the German advance. The Belgians prevented the Germans from taking the French ports by flooding their land. France responded to the German attack by launching an invasion of Alsace and Lorraine, but this did not work. They then made troops go to the front line. The german’s were then pushed back 40 miles. After this, the French and British went to secure the ports. The plan didn’t work out as well as they had wanted to. It was revised in 1905 due to the threat of Russia and France.
