Ystrad Tywi
By early 1282, many of the lesser princes who had supported Edward against Llywelyn in 1277 were becoming disillusioned with the exactions of the royal officers. On Palm Sunday that year, Dafydd ap Gruffydd attacked the English at Hawarden Castle and then laid siege to Rhuddlan. The revolt quickly spread to other parts of Wales, with Aberystwyth castle captured and burnt and rebellion in Ystrad Tywi in south Wales, also inspired by Dafydd according to the annals, where Carreg Cennen castle was captured.
