“We are made weak both by idleness and distrust of ourselves. Unfortunate, indeed, is he who suffers from both. If he is a mere individual he becomes nothing; if he is a king he is lost.”

“He who fears being conquered is sure of defeat.”

“A commander in chief ought to say to himself several times a day: If the enemy should appear on my front, on my right, on my left, what would I do? And if the question finds him uncertain, he is not well placed, he is not as he should be, and he should remedy it.”

“He who cannot look over a battlefield with a dry eye, causes the death of many men uselessly.”

“Never interrupt your enemy when he is making a mistake.”

“Never tell your enemy he is doing the wrong thing.”

“A commander-in-chief cannot take as an excuse for his mistakes in warfare an order given by his sovereign or his minister, when the person giving the order is absent from the field of operations and is imperfectly aware or wholly unaware of the latest state of affairs. It follows that any commander-in-chief who undertakes to carry out a plan which he considers defective is at fault; he must put forward his reasons, insist on the plan being changed, and finally tender his resignation rather than be the instrument of his army's downfall.”
