The approach of Stephen’s army, early in February, warned the Scottish leaders that it was time to collect their scattered forces either for battle or retreat; but David, who was in secret correspondence with many of Stephen’s barons, entertained the hope of finishing the war by a stratagem, without the hazard of a contest. All of the wretched country-people who had escaped the slaughter--and they were principally women--were either bartered for cattle on the spot, or driven northward with the prospect of a hopeless captivity; whilst the main body of the Scottish army withdrew to a small morass in the neighbourhood of Roxburgh, inaccessible except to the few who possessed an intimate knowledge of the locality. The burghers of the town were instructed to throw open their gates, and admit the English army without resistance; as it was David’s intention to enter with his followers in the dead of night, and surprise Stephen in his fancied security, calculating, that by the capture of the English king and his principal adherents, the war would be brought to a successful conclusion; the accession of the empress secured; and his own claims upon Northumberland readily acknowledged by his grateful niece. But though in the multitude of counsellors there may be wisdom, in the multitude of confidants there is little chance of secrecy; and through some unknown channel Stephen became aware of his enemy’s intentions. Avoiding Roxburgh, he retaliated upon other Scottish districts the injuries which had been inflicted on the north of England; but as he began to entertain suspicions of the fidelity of certain barons, and his army was weakened, as well by the want of provisions as by the religious scruples--either real or pretended--of several of his followers who objected to bearing arms in Lent, he soon retraced his steps towards the south, first possessing himself of Bamborough on his passage through Northumberland, and placing in it a garrison on which he could depend. The castle belonged to Eustace Fitz-John, a powerful baron, of whose fidelity the king was so mistrustful, that, contrary to all feudal precedent, he caused his person to be seized whilst in actual attendance at court upon a summons of military service; and Eustace was not restored to liberty until he yielded up to Stephen the key-stone of his power in the north, long famous as the ancient residence of the royal race of Ida, and the strongest fortress in Northumberland.[241]
