At that period, Dr. Thomas Hutton, a man of intellect and perception, was in Brittany as English embassador, ostensibly to ascertain whether or not Duke Francis gave any countenance to the Woodvilles, but, doubtless, with secret instructions to defeat the machinations of the exiles at Vannes. Hutton, who had an eye to see and a brain to comprehend, soon became aware of Buckingham's plot, and endeavored to persuade the Duke of Brittany to detain Richmond. But, when the duke, who was already committed, declined to interfere, the embassador sent such intelligence to England as enabled Richard to form a clear notion of the conspiracy formed to hurl him from the throne. Nevertheless, Richmond, with forty ships and five thousand Bretons, sailed from St. Malo. But his voyage was the reverse of prosperous; and on the very evening when the adventurers put to sea a violent tempest dispersed the fleet. Only the ship which carried Richmond, attended by a single bark, held on her course, and reached the mouth of Poole Harbor, on the coast of Dorset. And now the Welsh earl had startling proof of Hutton's vigilance. On approaching the English coast, Richmond perceived crowds of armed men, and immediately suspected a snare. However, he sent a boat ashore to ascertain whether they were friends or foes, and his messengers returned with information that the soldiers were friends, waiting to escort him to Buckingham's camp. But Richmond, too cautious to land with so slender a force in an enemy's country, resolved on sailing back to St. Malo. The wind being favorable, Richmond soon came in sight of Normandy, and after a short stay on that coast he returned to Brittany. Meanwhile, Buckingham's insurrection began, and in autumn Richmond was proclaimed king at various places in England. At the same time, the duke, at the head of a large body of Welshmen, marched from his castle and moved toward the Severn, his first object being to join the Courtenays. Matters immediately assumed a gloomy aspect; and Buckingham found that heading an insurgent army was less agreeable than dancing with princesses at Windsor, or displaying his gorgeous attire before the citizens of London. While he was blundering along the right bank of the Severn in search of a ford, autumnal rains rendered every ford impassable; and the river, rapidly overflowing its banks, inundated the country around. A scene replete with horrors was the consequence. Houses were overthrown; men were drowned in their beds; children were carried about swimming in cradles; and beasts of burden and beasts of prey were drowned in the fields and on the hills. Such a flood had never been experienced within the memory of man; and, for centuries after, it was remembered along the banks of the Severn as "the Duke of Buckingham's water."
