History of the Peloponnesian War

After this the Athenians told the Mendaeans that they might retain their civil rights, and themselves judge the supposed authors of the revolt; and cut off the party in the citadel by a wall built down to the sea on either side, appointing troops to maintain the blockade. Having thus secured Mende, they proceeded against Scione.

The Scionaeans and Peloponnesians marched out against them, occupying a strong hill in front of the town, which had to be captured by the enemy before they could invest the place.

The Athenians stormed the hill, defeated and dislodged its occupants, and having encamped and set up a trophy, prepared for the work of circumvallation.

Not long after they had begun their operations, the auxiliaries besieged in the citadel of Mende forced the guard by the sea side and arrived by night at Scione, into which most of them succeeded in entering, passing through the besieging army.
