Editor says, in authoring this post we have repurpose content from Wikipedia which reports ~ Montfort divided his army into three squadrons, and then led them across the Garonne to meet the Aragonese forces. Peter's ally and brother-in-law, Count Raymond, advised a defensive posture in order to weaken the advancing enemy with bowshot and javelins. Peter rejected this suggestion as unknightly and dishonorable. King Peter rode to the front line, forsaking his royal armor for the plain armor of a common soldier. His army was disorderly and confused. When Montfort's first squadron charged the field, the Aragonese cavalry was crushed and Peter himself was unhorsed. He cried out, "I am the king!" but was killed regardless. With the realization that their king had been killed, the Aragonese forces broke in panic and fled, pursued by Montfort's Crusaders.
