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.
In warfare, first lay plans which will ensure victory, and then lead your army to battle; if you will not begin with stratagem but rely on brute strength alone, victory will no longer be assured.
The conviction of the justification of using even the most brutal weapons is always dependent on the presence of a fanatical belief in the necessity of the victory of a revolutionary new order on this globe.
