Richard, of course, soon found out the character of the insurrection and those implicated in it. To Buckingham he first sent a "very kind obliging letter," inviting him to come to London, but the Duke "pretended indisposition," and so excused himself. The King thereon being enraged, sent him "a letter in a rougher stile, commanding him on his allegiance to attend him." But the die was cast, matters had gone too far to recede, and the message was returned by the Duke, "that he would not expose himself to his mortal enemy, whom he neither loved nor would serve."
Buckingham gathered together as soon as possible his "rash-levied" strength. These consisted of a number of his tenants and a host of ill-disciplined Welshmen, and he endeavoured by long marches, passing through the Forest of Dean, to get to Gloucester, and thence onward to join the western contingent. The Earl of Richmond set sail from Brittany, the twelfth of October, with a fleet of forty ships and five thousand Bretons on board. They appear to have at once encountered a storm, which dispersed the fleet, but
"the ship in which was the Earl in person, was driven on the coast of England, to the mouth of the haven of Poole, in Dorsetshire; where, finding the shore was crowded with troops to oppose his descent, he forbad any of his men to land until the whole navy came up. However he sent out his boat with some officers to demand of the men who stood on the shore, whether they were friends or enemies? These traitors instructed by king Richard, answered, 'They were friends posted there by the Duke of Bucks to receive the Earl of Richmond.' The Earl suspecting the deceit, and perceiving he was alone, the rest of his fleet not appearing, weighed anchor, returned to France, and landed in Normandy."
But how fared Buckingham and his motley host? Not only circumstances, but Nature fought against him. The river Severn, swollen by ten days continuous rain, overflowed all the adjoining country, doing immense damage, and the inundation was so large, and of such remarkable character, that for a hundred years afterward it was named and recollected as _The Great Water_, or _Buckingham's Water_, and tradition delivers it was so severe "that men, women, and children were carried away in their beds with the violence of it."
