take them 6 weeks (40 days) but it took them a total of 10 days. The plan was changed after Schlieffen was no longer chief of staff the time when the war broke out.
He was replaced by Helmut von Moltke (the younger). The changes he made to the plan is for them not to invade Netherlands but to only invade Belgium. Just looking at the numbers of men objectively, it seems unsure that there were enough numbers of german troops to attain and achieve the encirclement of Paris and to take the remaining french troops southwards. Not only that there weren’t the right amount of men initially, but casualties couldn’t be properly replaced. The regular german army was well equipped, but the replacement troops weren’t. They were not even trained with the new types of equipment. Germans misinterpreted on how things would be in the east. They dismissed Russia as a strong enemy and did not really think on how they would fight the Russians since they lost to japan in the Russo-Japanese war. The plan in 1914 ignored how Russia had modernized. Unfortunately, after the Archduke Franz Ferdinand was assassinated things did not go as planned. One of the german troop was just ready to give up as there were many adjustments to the plan. He said that not most of it went on how they
expected. While marching through Belgium, little did they know that they were connected with Britain, and Britain and France and allies. They did not expect that the British army would interfere. At that point, Moltke was not in a good position. He was forced to take troops from Belgium, so difficult and time consuming. He was facing many problems, and that vexed him very much. He had some difficulties with making the generals obey his exact orders. He was in shock in did not know what to do when things just went out of hands. Many families of the soldiers were shook about the failure.
