"Ye shall give credence to the bringer of this letter, and I beseech you to reward him to his costs; for I am not in power at the making of this letter to give him but as I was put in trust by favor of strange people. Also, ye shall send me, in all haste, all the ready money ye can make, and as many of my men as can come well horsed, and that they come in divers parcels. Also, that my best horses be sent with my steel saddles, and bid the yeoman of the horse cover them with leather.
"Also, ye shall send to my mother and let her weet of this letter, and pray her of her blessing, and bid her send me my casket, by this token, that she hath the key thereof, but it is broken. And ye shall send to the Prior of Thetford, and bid him send me the sum of gold that he said I should have; also say to him, by this token, that I showed him the first Privy Seal....
"Also, ye shall be of good cheer, and take no thought; for I shall bring my purpose about now, by the grace of God, who have you in His keeping."
Oxford soon learned the truth of the homely proverb that there is much between the cup and the lip; and when Tewkesbury extinguished his hopes of victory, the earl, attended by Lord Beaumont, betook himself to France. His reception in that country not being such as to tempt a prolonged residence, he fitted out a fleet, and for a while made the ocean his home. Indeed, it would seem that, when exiled from his kindred and his castles, the heir of the De Veres reverted to the habits of his Scandinavian ancestors, and that, during the summer of 1471, the thirteenth of the proud earls of Oxford roved the narrow seas as a pirate. About the close of September, however, Oxford, having, in the words of Speede, "gotten stores of provisions by the strong hand at sea," landed in Cornwall; and with a body of men, whom some chroniclers represent as well-nigh four hundred, and others as less than a sixth of that number, appeared suddenly at St. Michael's Mount.
The monks of St. Michael and the soldiers who garrisoned the Mount were in no condition to resist a body of men so determined. They therefore yielded without a struggle; and Oxford set himself to the task of repairing the fortifications, getting men and ammunition to defend the Mount in the event of a siege, and procuring provisions to subsist them in case of the operations being prolonged. Men and supplies were both forthcoming, for the earl happened to be grandson of an heiress of Sir Richard Sergeaux of Colquite, and their regard for the memory of that lady made the Cornishmen most eager to prove their devotion to his service. When, therefore, Oxford or his men descended into the villages adjacent to the Mount, they were received with enthusiasm, and, in the words of the chronicler, "had good cheer of the inhabitants."
Oxford's enterprise seemed to have prospered; but the period was the reverse of favorable for a Lancastrian lord being left in undisturbed possession of a strong-hold. No sooner did Edward hear of the exploit, than he issued a proclamation branding De Vere and his adherents as traitors; and, at the same time, he ordered Sir John Arundel, Sheriff of Cornwall, to retake St. Michael's Mount without delay. Arundel raised an army in the locality, advanced to the Mount, and sent a trumpeter to summon Oxford to surrender to the king's mercy, and thus save the effusion of Christian blood. The earl was uninfluenced by the ceremony. He resolutely refused to listen to the conditions. "Rather than yield on such terms," said he, "I and those with me will lose our lives."
The sheriff, seeing no hope of a capitulation, proceeded to storm the Mount. Oxford, however, far from being daunted, defended the strong-hold with such energy that, after a struggle, the besiegers were beaten at all points and repulsed with loss. Nor was this the worst; for the garrison, sallying from the outer gate, pursued the assailants down to the sands. There Arundel was slain with many of his soldiers; and the survivors—most of whom were newly levied—fled in dismay.[14]
Arundel was buried in the Church of the Mount; and Edward, on hearing of the sheriff's death, appointed a gentleman named Fortescue as successor in the office. Having been ordered to prosecute the siege, Fortescue commenced operations. But the new sheriff was little more successful than his predecessor. Moreover, the Mount, which was connected with the main land by an isthmus, dry at low water, but at other times overflowed, gained the reputation of being impregnable; and the king, who ascribed the want of success to the want of loyal zeal, and described Cornwall as "the back door of rebellion," instructed Fortescue to hold a parley with Oxford in order to ascertain the earl's desires and expectations.
