Translation of a Letter From Marshal Foch to Major General A. W.
Greely, Dated Malsherbe, October 23, 1920
MY DEAR GENERAL:
Colonel Ardant du Picq was the exponent of moral force, the most powerful element in the strength of armies. He has shown it to be the preponderating influence in the outcome of battles.
Your son has accomplished a very valuable work in translating his writings. One finds his conclusions amply verified in the experience of the American Army during the last war, notably in the campaign of 1918.
Accept, my dear General, my best regards.
F. FOCH.
