Satisfied with the earl’s concessions, the king withdrew from his territories; again proceeding northwards as far as Nairn in the course of the same autumn, to await the fulfilment of the treaty. On his return from hunting late one evening, he found Earl Harald in attendance with two children, his nephews, whom he offered in the place of his own son as hostages for his fidelity and allegiance. Surprised at this evasion of their agreement, the king demanded the reason of it, remarking upon the absence of Thorfin, whom Harald had promised as a hostage. The earl’s reply was remarkable, though it could scarcely be considered satisfactory. Thorfin, he said, was his only son, and he was reluctant to part with the sole heir of his earldom; and as for the enemies of the king whom he had promised to deliver into his hands, they had actually accompanied him as far as the port of Lochloy, within a few miles of Nairn, when he had suffered them to escape, reflecting that their doom was certain if once surrendered to the king.[477] As it is impossible that the earl could have imagined for one moment that William would permit so palpable an evasion of their treaty, it can only be supposed that, repenting of his promise as he approached Nairn, he preferred braving the royal anger by conniving at the escape of his prisoners, to surrendering friends, and probably connections, of his own, or of his wife, to the certain doom of death; or the even worse alternative of perpetual imprisonment, with probable mutilation or loss of sight. William and his barons in council--the peers of the earl, before whom he was immediately arraigned--at once pronounced him guilty of a breach of fealty, declaring that he had thereby forfeited his liberty; and he was carried in the train of William to the south, and retained in custody until, upon the arrival of his son Thorfin, he was released from captivity, and permitted to return to the Orkneys.[478] [Sidenote: A.
