Niccolò Machiavelli,
The Art of War — Book 7
(1675)
“ What benefits the enemy, harms you; and what benefits you, harm the enemy. Whoever is more vigilant in observing the designs of the enemy in war, and endures much hardship in training his army, will incur fewer dangers, and can have greater hope for victory. Never lead your soldiers into an engagement unless you are assured of their courage, know they are without fear, and are organized, and never make an attempt unless you see they hope for victory. It is better to defeat the enemy by hunger than with steel; in such victory fortune counts more than virtu. ”
