This is what the besieged Phocians did with the Thessalian footsoldiers. When the Thessalian horsemen rode into their country, the Phocians did them mortal harm; they dug a great pit in the pass near +Hyampolis [22.9,38.6] (Perseus) Hyampolis and put empty jars inside it. They then covered it with earth till all was like the rest of the ground and awaited the onset of the Thessalians. These rode on intending to sweep the Phocians before them, and fell in among the jars, whereby their horses' legs were broken.
