It was in vain that the guardians of young William exerted all their energies to establish his power. One pretender after another was put down by the strong hand. But the old Norman seigneurs, who had submitted with reluctance to the rule of legitimate princes, steeled their hearts against the humiliation of bending their knees to a bastard. Among the nobles of Normandy, by far the haughtiest and most turbulent were the seigneurs of Bessi and Cotentin. These men were proud to excess of their Norwegian descent, and very tenacious of their Scandinavian traditions and customs. Indeed, they treated with something like contempt the conversion of the Normans to Christianity, carried pagan devices on their shields, and rode into battle with the old Scandinavian war-cry of "Thor aide!" Rejoicing, above all things, in the purity of their blood, these ancient seigneurs not only talked with ridicule of the idea of submitting to the son of Arlette, but formed a strong league, marshalled their fighting men, and prepared to display their banners and seize William's person. When this conspiracy was formed, William had attained his seventeenth year, and, utterly unconscious of his danger, was residing in a castle unprepared for defence. The Counts of Bessi and Cotentin were making ready to mount their war-steeds and secure their prey, when one of their household fools stole away during the night, reached the castle where William was, clamoured for admittance in a loud voice, and would not be silenced till led to the young duke's presence. On getting audience of William, the fool hastily told him of his peril, and warned him to fly instantly. "What say you?" asked William in surprise. "I tell you," answered the fool, "that your enemies are coming, and, if you don't fly without delay, you'll be slain." After some further questioning, William resolved to take the fool's advice, and mounting, spurred rapidly towards the Castle of Falaise. But he was imperfectly acquainted with the country; and he had not ridden far when he missed his way. William reined up his steed, and halted in perplexity and dismay; and his alarm was increased by hearing sounds as of enemies following at no great distance. Fortunately, at that moment, however, he met a peasant, who, by pointing out the way to the fugitive, and setting the pursuers off in a wrong direction, enabled the duke to reach Falaise in safety.
