Little fighting could be done against those of the enemy who were continually being caught up into their ranks or attacking them from the rear, and they wrought most harm to themselves. For when a man had drawn his sword or poised his spear, he could not recover or sheathe his weapon again, but it would pass through those who stood in its way, and so they died from one another's blows.
