Next day the army marched for Hexham; But the rebels having already passed southward, General Wade retraced. his steps to Newcastle to gain the high road leading to Yorkshire, whither he marched in all haste; and for a time his army lay before Leeds on fields now covered with streets, some of which still bear the names of Wade-lane, Camp-road, and Camp-field, in consequence of the event. On the retreat of Prince Charles from Derby, General Wade again proceeded to Newcastle, while the Duke of Cumberland hung upon the rear of the rebels along their line of retreat by Penrith and Carlisle. Wade's army proceeded by forced marches into Scotland, and at length came up with the Highlanders at Falkirk. Metcalf continued with Captain Thornton and his company throughout all these marchings and countermarchings, determined to be of service to his master if he could, and at all events to see the end of the campaign. At the battle of Falkirk he played his company to the field; but it was a grossly-mismanaged battle on the part of the Royalist General, and the result was a total defeat. Twenty of Thornton's men were made prisoners, with the lieutenant and ensign. The Captain himself only escaped by taking refuge in a poor woman's house in the town of Falkirk, where he lay hidden for many days; Metcalf returning to Edinburgh with the rest of the defeated army. Some of the Dragoon officers, hearing of Jack's escape, sent for him to head-quarters at Holyrood, to question him about his Captain. One of them took occasion to speak ironically of Thornton's men, and asked Metcalf how he had contrived to escape. "Oh!" said Jack, "I found it easy to follow the sound of the Dragoons' horses-- they made such a clatter over the stones when flying from the Highlandmen. Another asked him how he, a blind man, durst venture upon such a service; to which Metcalf replied, that had he possessed a pair of good eyes, perhaps he would not have come there to risk the loss of them by gunpowder. No more questions were asked, and Jack withdrew; but he was not satisfied about the disappearance of Captain Thornton, and determined on going back to Falkirk, within the enemy's lines, to get news of him, and perhaps to rescue him, if that were still possible.
