Comyn, it seems, had broken an agreement between the two, and informed King Edward of Bruce's plans to be king. The agreement was that one of the two claimants would renounce his claim on the throne of Scotland, but receive lands from the other and support his claim. Comyn appears to have thought to get both the lands and the throne by betraying Bruce to the English. A messenger carrying documents from Comyn to Edward was captured by Bruce and his party, plainly implicating Comyn. Bruce then rallied the Scottish prelates and nobles behind him and had himself crowned King of Scots at Scone less than five weeks after the killing in Dumfries. He then began a new campaign to free his kingdom. After being defeated in the Battle of Methven, he was driven from the Scottish mainland as an outlaw as Edward I declared that his supporters would be given no quarter. Bruce returned to the mainland in 1307. King Robert's forces continued to grow in strength, encouraged in part by the death of Edward I in July 1307. The Battle of Loudon Hill, the Battle of Brander Pass, and the captures of Roxburgh Castle and Edinburgh Castle saw the English continually lose ground in their control of the country. The Battle of Bannockburn in 1314 was a pivotal event in the course of the war after which the English were totally pushed out of Scotland.
