It depends on him alone to conquer difficulties by his own superior talents and resolution. Never lose sight of this maxim, that you should establish your cantonments at the most distant and best protected point from the enemy, especially where a surprise is possible. By this means you will have time to unite all your forces before he can attack you. Artillery is more essential to cavalry than to infantry, because cavalry has no fire for its defense, but depends on the sabre. In war, the moral element and public opinion are half the battle.
Unity of command is essential to the economy of time.
War must be made as intense and awful as possible in order to make it short, and thus to diminish its horrors. I believe one bad general to be worth two good ones. War is like government, a matter of tact. The art of war is to gain time when your strength is inferior. An army which cannot be regularly recruited is a doomed army.
