It was probably on the night of August 6-7 that Douglas led the Scots army out of Stanhope Park. He took them across the morass, about a mile wide, over a causeway of branches, which the rear demolished as they passed. The men led their horses, and only a few baggage animals stuck fast. By daybreak the Scots were far on the way homewards. The English had been completely outwitted. On the day before, they had captured a Scots knight, who told them that orders had been issued 'for all to be armed by vespers and to follow the banner of Douglas,' he did not know where. The English lords suspected a night attack, and remained under arms. In the morning, two Scots trumpeters, who had been left to blow misleading blasts, were brought into camp. 'The Scots,' they said, 'are on the march home, since midnight; they left us behind to give you the information.' The English, fearing a ruse, continued to stand to their arms till their scouts confirmed the mortifying intelligence. The Scots were soon met by a considerable body of their countrymen under the Earl of March and Sir John the Steward. They all hurried back to Scotland by the western march. The English retired to Durham, and then to York, where the army was disbanded on August 15. Edward is said to have shed bitter tears over the collapse of his expedition. Some of the chroniclers allege unsupported charges of treachery, and mistakenly accuse Mortimer of accepting a heavy bribe to wink at the escape of the Scots. But the plain fact is that the English were outgeneralled at every turn. It was neither age nor sickness, as the chroniclers allege, that prevented King Robert from leading the Weardale foray. He was away in Ireland, creating a diversion. On July 12, at Glendun in Antrim, he granted a truce for a year to Henry de Maundeville, the English seneschal of Ulster, and his people, on condition of their delivering a certain quantity of wheat and barley at Lough Larne. The expedition does not seem to have been directly prosperous; the Irish, whom he had expected to rise and join him in Ulster, having apparently broken faith.
