The earl, struck dumb at this recital, gave the soldier time to recount the particulars. When he had finished, Lord Mar saw the necessity for instant flight, and ordered horses to be brought from the stables. Though he had fainted in the well, the present shock gave such tension to his nerves, that he found, in spite of his wound, he could now ride without difficulty. Halbert went as commanded, and returned with two horses. Having amongst rocks and glens to go, he did not bring one for himself; and begging the good soldier might attend the earl to Bothwell, he added, "He will guard you and this box, which Sir William Wallace holds as his life. What it contains I know not: and none, he says, may dare to search into. But you will take care of it for his sake, till more peaceful times allow him to reclaim his own!" "Fatal box!" cried the soldier, regarding it with an abhorrent eye, "that was the leading cause which brought Heselrigge to Ellerslie." "How?" inquired the earl. Grimsby then briefly related, that immediately after the return to Lanark of the detachment sent to Ellerslie, under the English garrison in Douglas, and told the governor that Sir William Wallace had that evening taken a quantity of treasure from the castle. His report was, that the English soldiers who stood near the Scottish knight when he mounted at the castle gate, saw a long iron coffer under his arm, but not suspecting its having belonged to Douglas, they thought not of it, till they overheard Sir John Monteith, as he passed through one of the galleries, muttering something about gold and a box. To intercept the robber amongst his native glens, the soldiers deemed impracticable, and therefore their captain came immediately to lay the information before the Governor of Lanark. As the scabbard found in the affray with young Arthur had betrayed the victor to have been Sir William Wallace, this intimation of his having been also the instrument of wrestling from the grasp of Heselrigge perhaps the most valuable spoil in Douglas exasperated him to the most vindictive excess. Inflamed with the double furies of revenge and avarice, he ordered out a new troop, and placing himself at its head, took the way to Ellerslie. One of the servants, whom some of Hambledon's men had seized for the sake of information, on being threatened with the torture, confessed to Heselrigge, that not only Sir William Wallace was in the house when it was attacked, but that the person whom he had rescued in the streets of Lanark, and who proved to be a wealthy nobleman, was there also. This whetted the eagerness of the governor to reach Ellerslie; and expecting to get a rich booty, without the most distant idea of the horrors he was going to perpetrate, a large detachment of men followed him.
