The authority of Wallace, however, whether _conferred_ or _assumed_, unfortunately for his country, was not destined to be of long duration. Soon after the defeat of the Earl of Pembroke, Edward, now reconciled to his barons, entered Scotland by the eastern marches, with a formidable army, consisting, according to English writers, of 3000 horsemen, armed at all points, 4000 of a lighter description, called _hobelars_, and 80,000 foot. A further reinforcement overtook him on his march, which swelled his forces to upwards of 100,000 fighting men, a great proportion of whom were veterans, inured to arms in the French wars. To oppose a power so overwhelming in the open field, the Guardian well knew would be in vain; he, therefore, again resorted to those measures which had already been found so effective: the population retired with their cattle and provisions before the approaching enemy, after destroying whatever they conceived might be useful to the invaders. While the Scottish army kept far in the advance, a strict _surveillance_ was exercised over the motions of their adversaries, so that few of the English scouts were able to return with any satisfactory account of the position or numbers of their opponents; and though most of the fortified places made little or no resistance, yet the supplies the conquerors found in the garrisons, did little to relieve that scarcity which soon began to be severely felt among the multitudes who followed the banner of England. In the meantime, the fleet which Edward had ordered to attend him with provisions being detained by contrary winds, he was compelled to wait their arrival; and, for this purpose, he fixed his head-quarters in the preceptory of the Knights Templars at Torphichen;[16] while part of his army occupied Temple-liston, thus keeping open his communication with the sea. Edward, in his march, had met with little annoyance, except from the stronghold of Dirleton, and two other castles in his rear, the garrisons of which made frequent sorties, and cut off several of his foraging parties. The Bishop of Durham was therefore ordered to lay siege to these fortresses. His efforts, however, were at first unsuccessful; he was driven from the walls of Dirleton with considerable loss; and as the force under his command was in want of provisions, as well as of a sufficient battering train, he sent Sir John Fitz-Marmaduke to represent his situation at head-quarters. “Go back,” said Edward, “and tell Antony that he is right to be pacific when he is acting the Bishop, but that in his present business he must forget his calling: and as for you, Marmaduke,” addressing the messenger, “You are a relentless soldier; I have often had to reprove you for too cruel exultation over the death of your enemies; but return now whence you came, and be as relentless as you choose, you will deserve my thanks, not my censure;--but look you do not see my face again till these three castles are razed to the ground.”[17]
