History of the Peloponnesian War

The Scionaeans and the Peloponnesians had come out against them and taken position on a strong hill before the city, which had to be taken by the enemy before the city could be invested with a wall.

So the Athenians made a furious assault upon the hill and dislodged those that were upon it; they then encamped and, after raising a trophy, prepared for the circumvallation.

But not long afterwards, when they were already at work, the auxiliaries who were besieged on the acropolis of Mende forced their way by night along the shore through the guard and reached Scione; and most of them escaped through the besieging army and got into the city.
