They advanced to Orestheum, in the Maenalian territory; and commanded those of the Arcadians who were their allies to muster and march close after them to Tegea; while they themselves, after coming all of them as far as Orestheum, from that place sent back home the sixth part of their force, in which were included those who were too old or too young for foreign service, to protect their property at home, and with the remainder of their army arrived at Tegea, where their allies from Arcadia joined them not long after.
