French endurance and the Allied method of repeated blows

The American Army learned quickly after arriving in Europe, but manpower alone could not reproduce years of combat experience. France held a far longer front and, in John Bull's interpretation, supplied a holding force capable of powerful attacks while the coalition's resources accumulated. Experienced Canadian and Australian formations became particularly effective striking forces. Repeated attacks at different points stopped Germany moving reinforcements along the line or withdrawing units to recover. Foch's overall command coordinated French, British, Dominion, American, and Indian contributions according to the roles they could perform. American units adopted useful Allied methods, although they had too little time to build the same depth of veteran experience throughout their ranks.
