Battle Studies; Ancient and Modern Battle

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.

PREFACE

BY FRANK H. SIMONDS Author of "History of the World War," "'They Shall Not Pass'--Verdun," Etc.

In presenting to the American reading public a translation of a volume written by an obscure French colonel, belonging to a defeated army, who fell on the eve of a battle which not alone gave France over to the enemy but disclosed a leadership so inapt as to awaken the suspicion of treason, one is faced by the inevitable interrogation--"Why?"

Yet the answer is simple. The value of the book of Ardant du Picq lies precisely in the fact that it contains not alone the unmistakable forecast of the defeat, itself, but a luminous statement of those fundamental principles, the neglect of which led to Gravelotte and Sedan.

Napoleon has said that in war the moral element is to all others as three is to one. Moreover, as du Picq impressively demonstrates, while all other circumstances change with time, the human element remains the same, capable of just so much endurance, sacrifice, effort, and no more. Thus, from Caesar to Foch, the essential factor in war endures unmodified.

And it is not the value of du Picq's book, as an explanation of the disasters of 1870, but of the triumphs of 1914-18, which gives it present and permanent interest. It is not as the forecast of why Bazaine, a type of all French commanders of the Franco-Prussian War, will fail, but why Foch, Joffre, Petain will succeed, that the volume invites reading to-day.

Beyond all else, the arresting circumstances in the fragmentary pages, perfect in themselves but incomplete in the conception of their author, is the intellectual and the moral kinship they reveal between the soldier who fell just before the crowning humiliation of Gravelotte and the victor of Fere Champenoise, the Yser and the colossal conflict of 1918 to which historians have already applied the name of the Battle of France, rightly to suggest its magnitude.

Read the hastily compiled lectures of Foch, the teacher of the Ecole de Guerre, recall the fugitive but impressive words of Foch, the soldier, uttered on the spur of the moment, filled with homely phrase, and piquant figure and underlying all, one encounters the same integral conception of war and of the relation of the moral to the physical, which fills the all too scanty pages of du Picq.

"For me as a soldier," writes du Picq, "the smallest detail caught on the spot and in the heat of action is more instructive than all the Thiers and the Jominis in the world." Compare this with Foch explaining to his friend Andre de Mariecourt, his own emotions at the critical hour at Fere Champenoise, when he had to invent something new to beguile soldiers who had retreated for weeks and been beaten for days. His tactical problem remained unchanged, but he must give his soldiers, tired with being beaten to the "old tune" a new air, which would appeal to them as new, something to which they had not been beaten, and the same philosophy appears.
