History of the Peloponnesian War

When they once gave ground, then were the lightarmed soldiers much more confident than before and pressed upon them with a mighty noise; and as many of the Lacedaemonians as they could intercept in their retreat they slew; but the most of them recovered the fort and together with the watch of the same put themselves in order to defend it in all parts that were subject to assault.

The Athenians following could not now encompass and hem them in, for the strong situation of the place, but, assaulting them in the face, sought only how to put them from the wall.

And thus they held out a long time, the better part of a day, either side tired with the fight and with thirst and with the sun, one endeavouring to drive the enemy from the top, the other to keep their ground. And the Lacedaemonians defended themselves easilier now than before because they were not now encompassed upon their flanks.
