History of the Peloponnesian War

The Peloponnesians, when they failed likewise of this, retaining a part of their army and dismissing the rest, enclosed the city about with a wall, dividing the circumference thereof to the charge of the several cities. There was a ditch both within and without it out of which they made their bricks;

and after it was finished, which was about the rising of Arcturus, they left a guard for one half of the wall (for the other was guarded by the Boeotians) and departed with the rest of their army and were dissolved according to their cities.

The Plataeans had before this sent their wives and children and all their unserviceable men to Athens. The rest were besieged, being in number of the Plataeans themselves four hundred, of Athenians eighty, and a hundred and ten women to dress their meat.

These were all when the siege was first laid and not one more, neither free nor bond, in the city. In this manner was the city besieged.
