The complete confirmation, however, of his weak, unsettled, poorly-ambitious mind, which led to his final defection and action against Richard, was doubtless due to the persuasive powers of his prisoner-guest, the wary, far-seeing, intellectual Morton, in whose hands, with plans carefully prepared, and subtle knowledge of the world and human life, Buckingham would be little more than a child. There is not however much to admire in this ecclesiastic's furtive flight from the custody of his host,--for his enforced sojourn at Brecknock Castle could be called in its conditions but little otherwise than that of a visitor. Then speedily placing himself in a position of safety, he left the seeds of disaffection he found sown in the mind of Buckingham, and which he had carefully nurtured, to ripen into foolish, hasty, miscalculated action, which revealed to Richard truly enough the character of the movement, that was destined in the end to deprive him of his kingdom and his life, but enabled him, as it turned out, easily to send this its first pioneer to the scaffold.
Sufficient stress does not appear to have been laid on this incident, and the influence it probably exercised, connected with the fate of Buckingham. His wretched downfall and unenviable character have consigned him to unpitying oblivion--the fate of many a better, but unsuccessful man,--while the brilliantly fortunate career of his quondam prisoner, has caused this circumstance to be forgotten, or passed over in silence. It is not inferred that Morton originally unsettled Buckingham's mind,--_that_ had taken place before,--but the fact remains he confirmed that unsettledness, pointed out the way in which he could be useful by hostile movement in the western counties, and then took speedy flight beyond seas to Richmond, where he remained in safety from the wrath of Richard, until after the battle of Bosworth.
Buckingham naturally did not want to part with his genial strong-minded prisoner and adviser,--but some excuse must nevertheless be allowed Morton for his hasty exit. He well knew the suspicion Richard had of him, and that king's jealousy of the strength of his ability and influence, which he believed was not loyal toward him, and the Bishop consequently being remitted to the custody of Buckingham. After Morton had tampered with Buckingham, completed his other traitorous negociations against Richard, and when circumstances were rapidly shaping themselves, if not with very defined and concentrated purpose, yet sufficiently large and apparent, as to render a hostile movement against Richard's authority an event of the shortest notice; and having also made full estimate of Buckingham's unreliable character and incapacity, and that no mercy would be meted out to him in such company, should an unsuccessful storm break forth and he fall into the hands of his victor,--which was just what did happen in Buckingham's case,--the first law of nature persuaded him, and he made for a place of safety under the shadow of his idol, there to wait further opportunity to aid, when the course of events afforded it.
