The war against the Athenians and their allies both parties shall wage in common;
and if they make peace, both shall make it in common. "4. Whatsoever forces shall be in the territory of the King, on the summons of the King, shall be maintained at the expense of the King. “5.
If any of the cities that have entered into this compact with the King shall go against the country of the King, the rest shall strive to prevent this and aid the King to the extent of their power; and if any of those who inhabit the King's territory or any territory over which the King has dominion shall go against the territory of the Lacedaemonians or of their allies, the King shall strive to prevent this and give aid to the extent of his power.”
After making this compact Therimenes turned over the command of the fleet to Astyochus and sailing away in a skiff was never seen again.[*](He was doubtless lost at sea. The word is used of unexplained disappearance in 4.80.4. Cf. also Xen. Hell., 1.6.38.)
