Et quoniam augebat iras militum scelestum facinus perfugae, quasi decurrentes in planum, ita iaculantes diversa missilia lacertis fortibus incumbebant, ut vergente in meridiem die, gentes acri repulsa disiectae, lacrimantes complurium mortes, tentoria repeterent vulnerum metu.
Translation :
And since the wicked deed of the deserter increased the soldiers' wrath, as if they were entering a level ground in a sham fight they used such strength of arm as they hurled their various weapons, that as the day inclined towards noon the enemy were scattered in bitter defeat, and lamenting the death of many of their number, retreated to their tents through fear of wounds.
