Having arranged for the defence of the fort by a scion of his family, the enemy may run in an opposite direction where it is possible for him to meet with friends, relatives, or wild tribes, or with his enemy's treacherous friends of vast resources, or where he may separate his enemy from the latter's friends, or where he may capture the enemy's rear, or country, or where he may prevent the transport of supplies to his enemy, or whence he may strike his enemy by throwing down trees at hand, or where he can find means to defend his own country or to gather reinforcements for his hereditary army; or he may go to any other country whence he can obtain peace on his own terms.
