Palm Sunday and the chronicle's case against Welsh resistance

A hostile chronicle describes the Welsh crossing their borders on Palm Sunday and attacking people taking part in religious processions. Its account portrays the Welsh as unwilling to live in peace. Part of its siege description is tentatively linked to Flint. It also presents Llywelyn, acting on his brother Dafydd's advice, as betraying his lord and king. A biblical comparison casts the king as someone betrayed by a person he loved. These are partisan accusations, and the passage is explicitly treated as propaganda. The religious framing gave Edward a way to justify a severe response after roughly five years of peace, short of actually calling a crusade.
