As we all know, the German offensives of March to June 1918 swept throgh the British and French lines, capturing huge quantities of men and matériel. This was achieved without tanks (in any quantity), but using the "new" stormtroop tactics.
It seems, though, that the stormtroop tactics went back to 1915, and weren't new at all. So the question is: why didn't the Allies think of them and save themslves the Somme, Chemin des Dames, Passchendaele, etc?
