The U. S entry into World war one was extremely important for the allies. It is fair to say that without the Americans, the allies might have lost Paris and therefore lost the war.
Their superior economy gave the allies and almost unlimited chain of supplies, ammunition and most importantly men. The effect was not just physical though. The morale of the German troops dropped greatly and mutinies and desertion was rife in their army, giving them one option, to retreat from the allies swarming fresh armies.
The immediate impacts that its entry brought about were on morale and naval warfare. The impact of America’s navy into the war had a sudden and prodigious effect. The effective cooperation between Britain and American navy staff delivered new and improved tactics and strategy. The most important of these was the convoy system. The allies had not adapted a convey system to protect their supply boats. Morison believed that “Sims found to his surprise, that the allies had not yet adopted the convey system… to be protected from submarines”.
The American’s instigated this system and it brought great results and enabled American troops to safely cross. After great success the US Navy also planned and executed a mine barrage across the North Sea, which blocked the exit to enemy submarines. Without the American navy it is probable that the allies would have been defeated before their ground troops even arrived. The American entry into the war had an enormous impact on morale. As American troops flooded in through Paris, the allies were joyous and finally believed that the war would now be won.
As R. Holmes believed “The Americans were like a transfusion of blood arriving to reanimate the pallid body of France”. Conversely, on the German side the soldiers now had to face the richest nation in the world, which would be able to send unlimited numbers of fresh men into the war. They were now battle worn and did not believe that they could win, only hoping they could live to see the allies win.
This morale decline brought desertion and mutiny, something the struggling German army could not cope with.Ludendorff knew what would come if they tried to play out the stalemate, so as a last roll of the dice affected the spring offensive. The American army did not have an immediate impact, but over time their ground troops proved instrumental in ending the spring offensive, and the successful counter offensive, which broke the German army. After German forces took more land in a few months than four years of war has experienced, allied generals panicked and if it were not for the new, fresh American troops we can never now whether Paris would have been conquered.When the allies coupled with the American forces in the consequential counter offensive it was the American armies huge numbers, which helped send Germany back.
It is evident that American had put a huge effort into the war as more than 116,000 died. The economic advantage the American entry offered was somewhat non-existent. England and the allies had heavily relied on American industry at the start of the war, as their own industry was largely mid-Victorian and could not build the huge and powerful war machines needed for war, or distribute the munitions quick enough. The Enemy is using tanks in large numbers.
When they appeared unexpectedly, especially after our positions were blanketed by smoke screens, they often broke the morale of our troops”. This meant that America was almost completely in control of Britain’s munitions supply, and by 1915 were equipping one-third of the British armies shells. However by 1917 the allies were no longer reliant on American industry with Britain taking over, supplying France, Italy and even American forces.
