The time was now arrived when the support of Sir Ringan Redhough and his borderers was become absolutely necessary. Without their co-operation in a more close and decisive manner than that in which they had hitherto conducted themselves, he could not now proceed one foot, and his great cause was ruined. He therefore dispatched a pressing message to the chief, conjuring him as his friend and fellow-soldier, either to come and supply his place in the blockade of Roxburgh, or march with all expedition to Melrose, and give battle to the governor of Berwick. The dogged and unyielding Warden returned for answer, that it had always been his chief and undivided aim to act in concert with his noble and gallant friend, and lord superior, the Earl of Douglas and Mar. But that he had a peculiar charge from his Sovereign, of the English marches, which it was his bounden duty to attend to, prior to all other considerations. Whatever he could do conformable with this first duty, should not be wanting. Finally, he sent him word, as he had done formerly, "that if he coudna take the castle, and confessed that he coudna take it, he might send word to him, and he wad take it for him." "What does the crabbed carle always mean by that answer?" said the Douglas, when it was reported to him: "Perhaps he has some means of communication with those within the fortress, some secret friend in disguise among our enemies. Perhaps he knows of some weak or accessible point among these extensive bulwarks, or perhaps he reckons on some plausible means of surmounting them; for the devil's head is not more fruitful in expedients than his. This is a matter of such importance to me at present, that I must try to probe it to the bottom. Were I sure that he could accomplish his boasted feat, I had better engage him to it with one-third of my dominions; and at all events, I must procure the active assistance of his energetic force at present, whatever may be the equivalent required. Let my white stead Beaver be caparisoned, and my attendants in readiness; I must have an interview with this man of the mountains before I sleep."
