I said no such thing.
The Germans developed the use of shock assault troops
using small unit tactics. Used earlier in the conflict
it might have made a difference in the out come.
The Kaiserschlact made a huge hole in the allied line
but they were in no position to continue the assault
and afterwards were always on the defensive until
the final collapse.
The French learned the lesson as well but they too
were in no condition to take it to victory.
...it was the French who figured out what needed to be done and how men needed to be trained in order to beat the Germans in WWone, but lacked the manpower to do it — so they were the key to the US’ Expeditionary Force’s record-time recruiting and deployment, and made a definite though under-credited contribution to the ultimate victory.
