"[H]e far transcended the two great inspirations of his life: Scharnhorst and Napoleon. Out of Scharnhorst's fragmentary and aphoristic heritage he developed the systematic, closely knit, perfectly balanced theory, in which every factor, every aspect, every argument had its place from which it could not be removed without fatally endangering the delicate balance of the whole. From the deep appreciation of the revolution wrought by Napoleon in the art of war, he reached an infinitely broader conception embracing within its elastic framework and majestic sweep every conceivable form of warfare and strategy... [T]he impression it made when it was published after his death through the devoted efforts of his widow and friends was extraordinary. The circle of those who noticed it was at first not large, and the magnitude of his achievement, even in its fragmentary form, was far too great to be taken in at once. But his perfect mastery of his subject, the intuitive genius with which he had succeeded in expressing what his contemporaries consciously or subconsciously felt, the charm of his style deeply affected all those who read it. By a process of infiltration, the influence of his ideas spread through the higher ranks of the army, influencing the thoughts of men and replacing the far more superficial, if much more easily assimilable, doctrines of his Swiss contemporary and rival Jomini. That process, going on unobtrusively throughout the middle decades of the 19th Century, came to a full and open conclusion after the sudden death of Reyher when the leadership of the General Staff was entrusted to Moltke, who combined in an almost perfect balance the technical mastery of the conduct of operations developed in the General Staff with his profound insight into the deeper issues developed in Clausewitz's great treatise."
