My centre is giving way, my right is in retreat, situation excellent. I attack. - Ferdinand Foch

There you have a country against which the Allies must take well-defined precautions. It is possible that its republican form of government will profoundly modify the German mentality. I devoutly hope so, but we cannot be sure. A well-organized, militarized Republic, however, might be as great a menace to its neighbours as the old Empire—although as yet we have no proof that the Republic can establish itself firmly in Germany.

Far from being a sum of distinct and partial results, victory is the consequence of efforts, some of which are victorious while others appear to be fruitless, which nevertheless all aim at a common goal, all drive at a common result: namely, at a decision, a conclusion which alone can provide victory.

This absence of similarity among military questions naturally brings out the inability of memory to solve them; also the sterility of invariable forms, such as figures, geometrical drawings (épures), plans (schémas), etc. One only right solution imposes itself : namely, the application, varying according to circumstances, of fixed principles.
