The most terrible of all my battles was the one before Moscow. The French showed themselves to be worthy of victory, but the Russians showed themselves worthy of being invincible.
As to moral courage, I have very rarely met with the two o'clock in the morning kind. I mean unprepared courage, that which is necessary on an unexpected occasion, and which, in spite of the most unforeseen events, leaves full freedom of judgement and decision.
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.
