A point of correction - this is the mythology of Pershing. American’s probably would have done well to fight in concert with the experienced Brits and French. Pershing’s basic strategy was ‘mindless attack’, which ALL the other combatants had wisely ceased.
By the second week of the Meuse-Argonne campaign, raw replacement troops, who had never even loaded or fired a rifle, were being sent to front line units.
The German army was a hard shell with little backing it up, supported by a starving populace. Tens of thousands of American deaths and innumerable casualties could have been avoided with a more thoughtful approach.
Utterly immoral, and not supported by the facts. The experienced British generals gave us late 1917 Ypres and other battles such as Flanders in 1918 that killed well over a quarter million allies at a whack while barely changing the lines from 1915.
British Generals “experience” was feeding soldiers into a meat grinder and being feted as heroes.
