War is like a game of chess ... but with this little difference, that in chess you may think over each move as long as you please and are not limited for time, and with this difference too, that a knight is always stronger than a pawn, and two pawns are always stronger than one, while in war a battalion is sometimes stronger than a division and sometimes weaker than a company. The relative strength of bodies of troops can never be known to anyone.... Success never depends, and never will depend, on position, or equipment, or even on numbers, and least of all on position.
