In March 1309, Bruce held his first parliament at St. Andrews and by August he controlled all of Scotland north of the River Tay. The following year, the clergy of Scotland recognised Bruce as king at a general council. The support given him by the church, in spite of his excommunication, was of great political importance. On 1 October 1310 Bruce wrote Edward II of England from Kildrum in Cumbernauld Parish in an unsuccessful attempt to establish peace between Scotland and England. Over the next three years, one English-held castle or outpost after another was captured and reduced: Linlithgow in 1310, Dumbarton in 1311, and Perth, by Bruce himself, in January 1312. Bruce also made raids into northern England and, landing at Ramsey in the Isle of Man, laid siege to Castle Rushen in Castletown, capturing it on 21 June 1313 and denying the English the island's strategic importance.
