The USA was the “deciding” factor. England was exhausted and even their leaders were fighting amongst themselves, including a great disagreement with Gen.Haig. They had no more reserves, and France was in like condition, having defended the huge majority of the battle line. America’s fresh troops, fresh supplies, tightly held control over contributing forces by Pershing, enabled the new troops to fight decisively. It was a weight of factors Germany couldn’t deal with, being exhausted themselves from the long war of attrition. Belleau Wood was a tremendous victory and the place is still called the Marine’s Wood even though in size as battles go, it was quite small. The third battle of Passchendaele was important for the Brits and Anzacs in 1917. Verdun was the site of five battles and many other sites like Chateau Thierry and St.-Mihiel tell the story. It was a ghastly war and was truly a World War, taking place everywhere. Even though we ignored the sinking of the Lusitania, we were bound to get in it.
But was it our business and who was actually the “right” side? Or was anyone?
