Battle Studies; Ancient and Modern Battle

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.
