 By May of that year Bruce was crowned King of Scots at Scone but early setbacks against English forces saw him seek refuge in the Western Isles and then in Ireland.In the spring of 1307 Bruce and his followers returned to the Scottish mainland and ambushed an English force under the command of Sir Aymer de Vallence at Glen Trool, Galloway.Worse was to follow for the beleaguered Vallence, when on 10 May 1307, he and his men were defeated by Bruce at Loudon Hill, Ayrshire.
