Xenophon Hellenica 7.2.4

[4] Again, when the enemy had retired from Lacedaemon, ¹ and the Argives, in anger at the devotion of the Phliasians toward the Lacedaemonians, had invaded the territory of Phlius in full force and were laying waste their land, even then they did not yield; but when the Argives were withdrawing, after having destroyed as much as they could, the horsemen of the Phliasians sallied forth and followed after them, and, although all the Argive horsemen and the companies posted behind them were employed to guard their rear, the Phliasians nevertheless, who were but sixty in number, attacked these troops and turned to flight the entire rearguard; to be sure they killed but few of them, yet they set up a trophy, with the Argives looking on, precisely as if they had killed them all.
