The
general must be first in the toils and fatigues of the army. In the
heat of summer he does not spread his parasol, nor in the cold of
winter don thick clothing ... . He waits until the army's wells have
been dug and only then drinks; until the army's food is cooked before
he eats; until the army's fortifications have been completed, to
shelter himself.
