Giovanna, I see that you are keeping up the good work, very nice writing!
Since you are making a summary of the whole crusade, allow me to fill some parts with little bit more details if you don't mind.
For instance, the inexplicable defeat of king Perre (known to me as Pedro) II of Aragon...
As you said, he did not approve of Simons growing ambitions. Being the man of the match on July 16, 1212. near Las Navas de Tolosa where the Christian army won a crushing victory over the Moors, Perre became an untouchable paladin of the Church, a secular saint. It came as a surprise when he demanded that the crusade in Languedoc be suspended immediately. He confronted Arnold Amaury on that matter, proposing to the pope that he would govern over all lands of Toulouse until Count Raymond's son attains manhood. He argued that Simon had overstepped himself, attacking lands over which Perre was suzerain, not infected with heresy, carving out a kingdom for himself. Perre had in mind a unification of Occitan- and Catalan-speaking lands under one monarch. He didn't like the idea of northern France taking the South...
The pope had written to Simon: "The illustrious king of Aragon complains that, not content with opposing heretics, you have led crusaders against Catholics, that you have shed the blood of innocent men and have wrongfully invaded the lands of his vassals, the counts of Foix and Comminges, Gaston of Bearn, while the king was making war on the Saracens." It was an order to end the crusade.
Amaury wasn't about to let the decade of his work be undone. He retorted that Perre never made any move in confronting heresy in his lands. And Simon had been doing precisely that. His work was not done.
The pope had to choose, between Perre and Simon and Amaury, between law of the land and the law of the Church.
On May 21, 1213. he reinstated the crusade.
The two armies met near Toulouse, at the castle of Muret, lying on the Garrone. Simon has managed to gather some 800-1000 heavy cavalry and about 1200 infantrymen. He was outnumbered approx. 20:1.
It was September 11, 1213, and Simon had made his last will and testament that morning. He was riding to give out to give battle.There was some last minute diplomacy that day but to no avail. The time for talk was over. Simon spend the night with his confessor and Perre with his mistress.
The next morning Perre summoned his council. Count Raymond of Toulouse was the only one who advised caution. Why not fortify their camp and wait for Simon to attack? He was ridiculed and put in charge of the reserve in case of emergency. Perre's plan was simple: he let Simon enter Muret unmolested where he would have to choose between an inevitable defeat in a long siege, or venture out to attack against overwhelming odds. Simon chose to attack. "If we cannot draw them a very long way form their tents, then there's nothing we can do but run." Those were his words, supposedly. The northerners armed themselves and a collective blessing had been given. They were ready for battle.
Simon's cavalry filed out a gate, forming three corps. They rode north of the castle, by the river bank, with Perre and the Occitans to their left. Perre led his cavalry into the plain, dividing it into two groups. Infantry was left behind, so the numbers were now 2:1 in Perre's favor. Simon's cavalry turned left and charged the first corps of the southerners. Stretched into a line, the first corps of Simon's cavalry, led by William of Contres, smashed into the southerners who reacted poorly to the charge. The melee was well under way when the second column of Simon's cavalry led by Bouchard de Marly made the second, decisive blow to the disorganized southerners. They were already dispersing when the second corps of southern cavalry led by king of Aragon appeared. The disciplined crusaders of William and Bouchard re-formed their lines quickly, and charged Perre. (According to the chronicles, Perre changed armor with one of his knights before the battle) As the crusaders were hacking their way to the man wearing the king's armor, Perre revealed himself and shouted in the confusion, "I am the king!" Was it in defiance or admission of defeat we'll never know. He wasn't heard, and was killed.
Back in the southern camp Raymond, never being accused of braver, did nothing to aid the cavalry and the disaster was complete. The news of Perre's death soon spread and the army at the camp started to disintegrate, fleeing in panic. The third crusader corps, Simon's corps, hunted them down some time and then turned on to the citizen soldiery from Toulouse that was before the walls of Muret, harassing the besieged, having heard a fatally false rumor that the Simon's men have been routed by king Perre. I suppose they were somewhat surprised when they saw Simon and his knights bearing down on them. The rest is an epic butchery, the lower estimation speaking of 7000 dead....
And that was the Battle of Muret.
And after lunch, a few quotations from the Council of Lateran...
