They who maintain that an enemy should be attacked in his own country,
cite the advice given by Croesus to Cyrus, when the latter had come to
the frontiers of the Massagetæ to make war on that people. For word
being sent by Tomyris their queen that Cyrus might, at his pleasure,
either enter her dominions, where she would await him, or else allow
her to come and meet him; and the matter being debated, Croesus,
contrary to the opinion of other advisers, counselled Cyrus to go
forward and meet the queen, urging that were he to defeat her at a
distance from her kingdom, he might not be able to take it from her,
since she would have time to repair her strength; whereas, were he to
defeat her within her own dominions, he could follow her up on her
flight, and, without giving her time to recover herself, deprive her of
her State. They cite also the advice given by Hannibal to Antiochus,
when the latter was meditating a war on the Romans. For Hannibal told
him that the Romans could not be vanquished except in Italy, where an
invader might turn to account the arms and resources of their friends,
whereas any one making war upon them out of Italy, and leaving that
country in their hands, would leave them an unfailing source whence to
draw whatever reinforcement they might need; and finally, he told him,
that the Romans might more easily be deprived of Rome than of their
empire, and of Italy more easily than of any of their other provinces.
They likewise instance Agathocles, who, being unequal to support a war
at home, invaded the Carthaginians, by whom he was being attacked, and
reduced them to sue for peace. They also cite Scipio, who to shift the
war from Italy, carried it into Africa.
Those who hold a contrary opinion contend that to have your enemy at a
disadvantage you must get him away from his home, alleging the case of
the Athenians, who while they carried on the war at their convenience
in their own territory, retained their superiority; but when they
quitted that territory, and went with their armies to Sicily, lost
their freedom. They cite also the fable of the poets wherein it is
figured that Antæus, king of Libya, being assailed by the Egyptian
Hercules, could not be overcome while he awaited his adversary within
the bounds of his own kingdom; but so soon as he was withdrawn from
these by the craft of Hercules, lost his kingdom and his life. Whence
the fable runs that Antæus, being son to the goddess Earth, when thrown
to the ground drew fresh strength from the Earth, his mother; and that
Hercules, perceiving this, held him up away from the Earth.
