New Cumnock known as Castle William, for upon this sted Sir William Wallace held a ryall house, a crown property. On 10 February 1306, Robert the Bruce killed John Comyn at Greyfriars Kirk, Dumfries. 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
Battle of Glen Trool most powerful men in Scotland, the previous year 1306. This led to a bitter civil war between the Bruce's faction and the Comyns and their allies, notably Edward I. After his defeat at the Battle of Methven and subsequently at the Battle of Dalry in the summer of 1306 the recently crowned King Robert was little better than a fugitive, disappearing altogether from the historical record for a number of months. It wasn't until the spring of 1307 that he made a reappearance, landing in the south-west of Scotland with soldiers recruited, for the most part, from the Western Isles.
