One day, when the three princes were in the palace, Henry and Louis commenced playing chess, while Curthose sat looking out on the banks of the Seine, or paced the room, pondering some vague project connected with love or war. Henry appears to have had marvellous luck; and Louis, perhaps not quite satisfied of having fair play, lost not only his money but his temper also. High words, and a quarrel not remarkable for princely dignity were the consequences. Louis, getting into a rage, perhaps for the first time in his life, called Henry the son of a bastard, and threw the chessmen in his face. Henry, provoked in the highest degree, reproached Louis with being the heir of usurping, effeminate, and priest-ridden kings, and felled him to the floor with the chessboard. In the vehemence of his passion, Henry would have slain Louis on the spot; but Curthose, recovering from the amazement produced by the scene, hastily interfered, dragged his brother away, and hurried to the stables. Mounting, the Norman princes spurred off with the speed of the wind, and scarcely halted till they were beyond the French frontier. On learning what had occurred, Philip swore to be avenged. Rousing himself from apathy, and availing himself of William's absence from the Continent, the French king made a hostile incursion into Normandy; and, ere long, the Conqueror, while in England, learned that his liege lord was ravaging his territory and besieging his towns. William was, by this time, in his sixty-third year, and by no means so energetic as in days gone by. Nevertheless, his spirit was high as ever. Resolved to go in person to face the danger and punish the aggression, he prepared to cross the Channel. Before doing so, however, he determined to remove from the vanquished islanders the temptation of making a last desperate effort to restore their national royalty. At this time, Edgar Atheling, and his sister, Christina, were both in England. The Atheling, with some touch of sentiment for the land over which his sires had reigned, had, in the previous year, returned from Normandy; and Christina, having perhaps exhausted the patience of King Malcolm, had returned from Scotland. The presence of the royal Saxons could hardly, under all the circumstances, have been of vital consequence. But suspicion had now become a disease with the Conqueror, and he could not embark without having first disposed of them to his satisfaction. Accordingly, he so strongly impressed upon Christina the propriety of becoming a religious, that the princess, albeit not yet forty, still comely to behold, and perhaps by no means averse to the veil of a bride, was fain to take the veil of a nun in the convent of Rumsey; and he demonstrated so clearly to Atheling the propriety of undertaking an expedition to the Holy Land, that the prince, after being promised money to support his dignity, consented to set out on a pilgrimage.
