The Kentishmen, on hearing this, consented to lay down their arms, having concluded a treaty by which they agreed to offer no further resistance, on condition that they should be as free as they had before been. William sent forward five hundred horsemen towards London; and learning that the citizens were likely to stand on their defence, he resolved to turn towards the west, and passed the Thames at Wallingford. On reaching Wallingford, which had been regarded by the Saxons as a stronghold of the first importance, William was struck with the capacity of the place, and eager to secure it as one of his strongholds. On this point there was no difficulty. In fact, Wallingford was in possession of a Saxon thane named Wigod, who had neither the will nor the power to resist, but who had an only daughter named Aldith, with no insuperable objection to become the bride of a Norman knight. The Conqueror immediately provided the fair Aldith with a husband, in the person of Robert D'Oyley, one of his favourite warriors; and the marriage ceremony having been performed without any unnecessary delay, D'Oyley was left, in the company of his bride and his father-in-law, to make the castle as strong as possible; while the Conqueror, marching to Berkhampstead, cut off all communication between London and the north, and continued so to hem in the city that the inhabitants became every day more apprehensive of being exposed to the horrors of famine. XXI. EDGAR ATHELING. News of the Norman victory at Hastings speedily reached London; and the city became the scene of commotion and debate. So strong, however, appeared the necessity for doing something decisive, that men calmed themselves to consider their position; and, by way of dealing with the crisis, they resolved on placing the Confessor's crown on the head of Edgar Atheling, the Confessor's kinsman, and the undoubted heir of the Saxon kings. Atheling was grandson of Edmund Ironsides, and a native of Hungary. In fact, it seems that when Canute the Dane, in 1017, made himself master of England, he found in the kingdom two sons of Ironsides, who bore the names of Edmund and Edward. Wishing, it is said, to have the Saxon princes put to death, but apprehensive of the consequences of ordering their execution, Canute sent them to the King of Sweden, with a request that they might be secretly made away with. Not caring, however, to have the blood of two innocent boys to answer for, the royal Swede sent them to Hungary; and the king of that country, after receiving them with reluctance, reared them with kindness. As time passed on, Edmund died without heirs; but Edward, known as The Exile, espousing Agatha, daughter of an Emperor of Germany, became father of a handsome and fair-haired boy, known as Edgar Atheling, and two girls, named Margaret and Christina.
