Lewis, finding himself unable to wrest Normandy from the king by force of arms, had recourse to the dangerous expedient of applying to the spiritual power, and of affording the ecclesiastics a pretence to interpose in the temporal concerns of princes. { 1019.} He carried young William to a general council, which was assembled at Rheims, by Pope Calixtus II., presented the Norman prince to them, complained of the manifest usurpation and injustice of Henry, craved the assistance of the church for reinstating the true heir in his dominions, and represented the enormity of detaining in captivity so brave a prince as Robert, one of the most eminent champions of the cross, and who, by that very quality, was placed under the immediate protection of the holy see. Henry knew how to defend the rights of his crown with vigor, and yet with dexterity. He had sent over the English bishops to this synod; but at the same time had warned them, that, if any further claims were started by the pope or the ecclesiastics, he was determined to adhere to the laws and customs of England and maintain the prerogatives transmitted to him by his predecessors. “Go,” said he to them, “salute the pope in my name; hear his apostolical precepts; but take care to bring none of his new inventions into my kingdom.” Finding, however, that it would be easier for him to elude than oppose the efforts of Calixtus, he gave his ambassadors orders to gain the pope and his favorites by liberal presents and promises. The complaints of the Norman prince were thenceforth heard with great coldness by the council; and Calixtus confessed, after a conference which he had the same sunaaier with Henry, and when that prince probably renewed his presents, that, of all men whom he had ever yet been acquainted with, he was, beyond comparison, the most eloquent and persuasive.
The warlike measures of Lewis proved as ineffectual as his intrigues. He had laid a scheme for surprising Noyon; but Henry, having received intelligence of the design, marched to the relief of the place, and suddenly attacked the French at Brenneville, as they were advancing towards it. A sharp conflict ensued, where Prince William behaved with great bravery, and the king himself was in the most imminent danger. He was wounded in the head by Crispin, a gallant Norman officer, who had followed the fortunes of William;[*] but being rather animated than terrified by the blow, he immediately beat his antagonist to the ground, and so encouraged his troops by the example, that they put the French to total rout, and had very nearly taken their king prisoner. The dignity of the persons engaged in this skirmish rendered it the most memorable action of the war; for in other respects it was not of great importance. There were nine hundred horsemen who fought on both sides, yet were there only two persons slain. The rest were defended by that heavy armor worn by the cavalry in those times.[**] An accommodation soon after ensued between the kings of France and England, and the interests of young William were entirely neglected in it.
