Wars, therefore, are to be undertaken for this end, that we may live in peace, without being injured; but when we obtain the victory, we must preserve those enemies who behaved without cruelty or inhumanity during the war.
So the principles of warfare are: Do not depend on the enemy not coming, but depend on our readiness against him. Do not depend on the enemy not attacking, but depend on our position that cannot be attacked.
Still, I have been no one's enemy but my own. My easy nature, either in drinking or anything else, was always ready to submit to persuasions of profligate companions, who often led me into snares.
