Meanwhile word came from their friends[*](As opposed to the faction mentioned at the end of ch. lxii.) in Tegea that, unless they should come quickly, Tegea would go over to the Argives and their allies, and already had all but done so.

Whereupon succour was sent, both of the Lacedaemonians themselves and of the Helots, in full force, promptly and on such a scale as never before.

These advanced to Orestheum in Maenalia, and gave orders to their allies among the Arcadians to get together and come close upon their heels to Tegea. After going, all together, as far as the Orestheum, they sent home from there a sixth part of their force—in which were included the older and younger men—to keep guard at home, and with the remainder of their army reached Tegea, where not long afterwards the allies from Arcadia arrived. They sent also to Corinth and to the Boeotians, Phocians and Locrians, bidding them bring aid in all haste to Mantinea.

But to some this was a sudden call, and it was not easy for them, except in a body and after waiting for one another, to go through the enemy's country; for that closed the way, lying just between. Nevertheless they hurried on.

But the Lacedaemonians, taking up the allies of the Arcadians that were present, invaded Mantinea, and encamping at the sanctuary of Heracles proceeded to ravage the country.
