King Edward attributed this ineffectual long siege of St. Michael’s Mount either to the cowardice or disloyalty of the Sheriffs and country people of Cornwall; but there was no just cause for this conjecture, since Sir John Arundell and several of his men lost their lives about it: at other times, he would say the inhabitants were more affected to the house of Lancaster than that of York; whereupon, when the said Mr. Fortescue went out of his office after four years’ service, he made his brother Richard Duke of Gloucester Sheriff of Cornwall during life; for that he was often heard to say he looked upon Cornwall only as the back-door of rebellion; so that those several persons set down in the catalogue of Sheriffs of Cornwall after Fortescue, were not absolute Sheriffs, but Deputies under the said Duke, viz. Daubeny, Carnesew, Willoughby, Nanfon, Grenvill, Fullford, Treffry, Terrill, and Houghton, who stiled themselves Vicecomes, and their under Sheriffs Sub-Vicecomes. PART IV. About the year of our Lord 1496, when James IV. King of Scotland, upon a truce with King Henry VII. of England, had expulsed from Scotland that counterfeit sham Prince, Perkin Warbeck (the pretended Richard of Shrewsbury, youngest son of King Edward IV. who had before been murdered in the Tower), to whom he had given in marriage his near kinswoman the Lady Katherine Gordon; he, together with his wife and family, sailed from thence over into Ireland, to seek friendship there of the rebels and all others well affected to the House of York; where being arrived, and fortune favouring him according to his expectation, news was brought him there that the Cornish rebels were ready to renew their former hostility, and venture their lives in battle upon the title of the house of York against that of Lancaster, had they a valiant and able General to lead them, notwithstanding Flammock and his confederates under the same engagement were defeated and executed in 1495.
