It now remained to attack the English garrisons who held the castles of Scotland. An invasion conducted by Edward II in 1310 proved fruitless, and the English king returned home to enter on a long quarrel with the Lords Ordainers, and to see his favourite, Gaveston, first exiled and then put to death. While the attention of the rulers of England was thus occupied, Bruce, for the first time since Wallace's inroad of 1297, carried the war into the enemy's country, invading the north of England both in 1311 and in 1312. Meanwhile the strongholds of the country were passing out of the English power. Linlithgow was recovered in 1311; Perth in January, 1312-13; and Roxburgh a month later. The romantic capture of the castle of Edinburgh, by Randolph, Earl of Moray, in March, 1313, is one of the classical stories of Scottish history, and in the summer of the same year, King Robert restored the Scottish rule in the Isle of Man. In November, 1313, only Stirling Castle remained in English hands, and Edward Bruce rashly agreed to raise the siege on condition that the garrison should surrender if they were not relieved by June 24th, 1314. Edward II determined to make a heroic effort to maintain this last vestige of English conquest, and his attempt to do so has become irrevocably associated with the Field of Bannockburn. In his preparations for the great struggle, which was to determine the fate of Scotland, the Bruce carefully avoided the errors which had led to Wallace's defeat at Falkirk. He selected a position which was covered, on one side by the Bannock Burn and a morass, and, on the other side, by the New Park or Forest. His front was protected by the stream and by the famous series of "pottes", or holes, covered over so as to deceive the English cavalry. The choice of this narrow position not only prevented the possibility of a flank attack, but also forced the great army of Edward II into a small space, where its numbers became a positive disadvantage. King Robert arranged his infantry in four divisions; in front were three schiltrons of pikemen, under Randolph, Edward Bruce, and Sir James Douglas, and Bruce himself commanded the reserve, which was composed of Highlanders from Argyll and the Islands and of the men of Carrick.[49] Sir Robert Keith, the Marischal, was in charge of a small body of cavalry, which did good service by driving back, at a critical moment, such archers as made their way through the forest. The English army was in ten divisions, but the limited area in which they had to fight interfered with their arrangement. As at Falkirk, the English cavalry made a gallant but useless charge against the schiltrons, but it was not possible again to save the day by means of archers, for the archers had no room to deploy, and could only make vain efforts to shoot over the heads of the horsemen. Bruce strengthened the Scots with his reserve, and then ensued a general action along the whole line.
