History of the Peloponnesian War

Advancing to Orestheum in Maenalia, they directed the Arcadians in their league to follow close after them to Tegea, and going on themselves as far as Orestheum, from thence sent back the sixth part of the Spartans, consisting of the oldest and youngest men, to guard their homes, and with the rest of their army arrived at Tegea; where their Arcadian allies soon after joined them.

Meanwhile they sent to Corinth, to the Boeotians, the Phocians, and Locrians, with orders to come up as quickly as possible to Mantinea. These had but short notice; and it was not easy except all together, and after waiting for each other, to pass through the enemy's country, which lay right across and blocked up the line of communication. Nevertheless they made what haste they could.
