Most famous of all is the story that supposedly at the height of the fighting, as the crusaders forced their way into the town, someone asked the legate Arnaud-Amaury how they would separate the good Christians from the heretics. His apocryphal words, Kill them, God knows who are his, reported by a Cistercian monk with a fanciful imagination, have become a byword for religious intolerance, placing what happened at Béziers on the top rung of pre-modern atrocities. Though Arnaud-Amaury was not above executing heretics, in 1210 this inflexible and unyielding man gave Cathars who surrendered a fair chance to abjure their heresy and so avoid execution, which heaps more doubt on the credibility of Caesarius' report. The speed and spontaneity of the attack indicate that the legate may not have actually known what was going on until it was over.
