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."

Buckingham was rudely awakened from his delusions. The flooded river and broken bridges created difficulties with which he could not cope. His enterprise—from the beginning never very promising—became utterly hopeless; and the Welshmen, losing heart and finding no provision made for their subsistence, turned their thoughts affectionately to the rude homes and the rude fare they had left behind. The result soon appeared. The Celtic warriors pretended to regard the flood as a sign that the insurrection was displeasing to Heaven, deserted their standards in crowds, and, without exception, returned to their mountains.

Buckingham now lost courage; and, while his confederates—Dorset, the Courtenays, Lord Welles, Sir William Brandon, and Sir John Cheyney—escaped to Richmond in Brittany, the duke fled to Shrewsbury, and took refuge in the house of one of his retainers, named Humphrey Bannister. Tempted by the reward offered for Buckingham's apprehension, Bannister betrayed his master; and the duke, having been conveyed to Salisbury, was beheaded, without trial, in the market-place.

When the conspiracy of Brecknock had been crushed, Richard summoned a Parliament, which declared him lawful sovereign, entailed the crown on his son, and passed a bill of attainder against those who had taken part in Buckingham's attempt at king-making. Nevertheless, Richard did not feel secure. The dread of an invasion, and of his enemies uniting Richmond and Elizabeth, kept the usurper uneasy, and he set himself boldly to the scheme of getting both the Welsh earl and the English princess in his power. The persons who could aid him in this were Peter Landois and Elizabeth Woodville.

The Duke of Brittany now reigned no longer save in name, and Peter Landois—son of a tailor—ruled the province with more than ducal power. Peter, though elevated to so high a position, was not proof to the temptation of a bribe; and Richard, by means of gold, converted him from a friend to an enemy of Richmond, and obtained his promise to send the Welsh earl a prisoner into England.

With Elizabeth Woodville Richard was equally successful. That lady, weary of the sanctuary, not only listened to his proposals, but went with her daughters to court, where Elizabeth, the eldest, was treated with the utmost distinction. Richard is supposed to have intended to match the princess with his son, a boy of eleven, but the death of the prince at Middleham defeated this plan for reconciling conflicting claims.
