Hellenica (2.4.4-2.4.8)

Then the Thirty, knowing that the enemy would also gather plunder from the farms if there were no force to protect them, sent out all but a few of the Laconian guardsmen and two divisions of the cavalry to the outlying districts about fifteen stadia from Phyle. These troops made their camp in a bushy spot and proceeded to keep guard.

Now by this time about seven hundred men were gathered at Phyle, and during the night Thrasybulus marched down with[*] them; and about three or four stadia from the guardsmen he had his troops ground their arms and keep quiet.

Then when it was drawing towards day and the enemy were already getting up and going away from their camp whithersoever each one had to go, and the grooms were keeping up a hubbub as they curried their horses, at this moment Thrasybulus and his men picked up their arms and charged on the run. They struck down some of the enemy and turned them all to flight, pursuing them for six or seven stadia; and they killed more than one hundred and twenty of the hoplites, and among the cavalry Nicostratus, nicknamed the beautiful, and two more besides, catching them while still in their beds.

Then after returning from the pursuit and erecting a trophy and packing up all the arms and baggage they had captured, they went back to Phyle. And when the cavalry from the city came to the rescue, there were none of the enemy left to be seen; so after waiting until their relatives had taken up the bodies of the dead, they returned to the city.
