In the meantime, the men of religion who were present began to exert themselves to prevent so fratricidal a collision of these armies, between whose opposing ranks so many families were divided. Henry yielded to their wishes, and offered to his brother terms of reconciliation which reveal not merely his belief in the strength of his position in the country and his confidence of success, but something also of his general motive. The ardour of religious zeal which the historian makes Henry profess we may perhaps set aside, but the actual terms offered speak for themselves. Robert was to surrender to Henry all the castles and the jurisdiction and administration of the whole duchy. This being done, Henry would turn over to him, without any exertion on his part, the revenues of half the duchy to enjoy freely in the kind of life that best pleased him. If Robert had been a different sort of man, we should commend his rejection of these terms. Possibly he recalled Henry's earlier promise of a pension, and had little confidence in the certainty of revenues from this source. But Henry, knowing the men whose advice Robert would ask before answering, had probably not expected his terms to be accepted. The battle was fought on September 28, and it was fiercely fought, the hardest fight and with the largest forces of any in which Normans or Englishmen had been engaged for forty years. The main body of both armies fought on foot. The Count of Mortain, in command of Robert's first division, charged Henry's front, but was met with a resistance which he could not overcome. In the midst of this struggle Robert's flank was charged by Henry's mounted allies, under Count Elias of Maine, and his position was cut in two. Robert of Bellême, who commanded the rear division, seeing the battle going against the duke, took to flight and left the rest of the army to its fate. This was apparently to surrender in a body. Henry reports the number of common soldiers whom he had taken as ten thousand, too large a figure, no doubt, but implying the capture of Robert's whole force. His prisoners of name comprised all the leaders of his brother's side except Robert of Bellême, including the duke himself, Edgar the English atheling, who was soon released, and William of Mortain. The victory at once made Henry master of Normandy. There could be no further question of this, and it is of interest to note that the historian, William of Malmesbury, who in his own person typifies the union of English and Norman, both in blood and in spirit, records the fact that the day was the same as that on which the Conqueror had landed forty years earlier, and regards the result as reversing that event, and as making Normandy subject to England. This was not far from its real historical meaning.
