One does simply what one can in order to apply what one knows. - Ferdinand Foch

The truth is, no study is possible on the battle-field; one does there simply what one can in order to apply what one knows. Therefore, in order to do even a little, one has already to know a great deal and to know it well.

I was convinced then—and my conviction has not since faltered—that the Treaty [of Versailles] then in the making, which I was not allowed to modify, was bad for the safety of France. Very bad. It was full of flaws, it was fundamentally wrong, and cannot fail one day to have the worst results. On the day when it is apparent in all its evil, when France perceives that her interests were improperly defended, she will rise in deep anger against those who so imperfectly handled that defence.
