Unless you know the mountains and the forests, the defiles and impasses, the lay of the marshes and swamps, you cannot maneuver with an armed force. Unless you use local guides, you cannot get the advantages of the land.
Despite those titles, power, and pelf, The wretch, concentred all in self, Living, shall forfeit fair renown, And, doubly dying, shall go down To the vile dust, from whence he sprung, Unwept, unhonor'd, and unsung.
