The beginning of the war.. Considered a ‘War of Attrition.’ This means that both sides had no huge strength or advantage. Also, both had very similar materials.
Middle of the War.. Towards the middle of the war, the allies began to block Germany’s overseas supplies from coming into the country. Meanwhile, the allies were getting some resources through America.
The Allies Victory Germany spent all of their remaining resources on one more big push that led to them failing. Germany started running out of men, funs, shells, bullets, food, horses, and more. When the United States came into battle, they bought along a whole new group of soldiers and more, fresher materials.
