If the statement, commonly accepted by historians, be authentic, that 30,000 perished on the field and in the flight, then about one half of Edward's army must have been slaughtered—an unusual proportion even in the greatest disasters. No doubt the common soldiers fared miserably in their flight. Sir Maurice de Berkeley, in command of the Welsh, led them towards the Border; but the countrymen rose and slew many of them in detail among the moors. Væ victis! the power of England was shattered for the time, and none may reckon the amount of individual disaster.
