This soldier, I realized, must have had friends at home and in his regiment; yet he lay there deserted by all except his dog. I looked on, unmoved, at battles which decided the future of nations. Tearless, I had given orders which brought death to thousands. Yet here I was stirred, profoundly stirred, stirred to tears. And by what? By the grief of one dog. Napoleon Bonaparte, on finding a dog beside the body of his dead master, licking his face and howling, on a moonlit field after a battle. Napoleon was haunted by this scene until his own death.
Sometimes a single battle decides everything and sometimes, too, the slightest circumstance decides the issue of a battle. There is a moment in every battle at which the least manoeuvre is decisive and gives superiority, as one drop of water causes overflow.
In politics nothing is immutable. Events carry within them an invincible power. The unwise destroy themselves in resistance. The skillful accept events, take strong hold of them and direct them.
