The Danes who remained in England had reacquired a taste for adventurous expeditions. They assembled along the coast of Northumberland to organize an attack on the southern portion of the kingdom; but Alfred had long resolved to fight his enemies with their own weapons. Having ridded himself of Hastings, he had had time to look to his navy, and the Danes found themselves opposed by vessels larger and more rapid than their own. The struggle began on all sides. Wherever the pirates advanced to the attack they found Saxon vessels to check them. The contests were of frequent occurrence; they were not invariably favorable to the Saxons, but the Danes suffered great losses: their ships would often founder on the coast and the cargo would be lost. In 897, the last Danish ships disappeared from England. Alfred had now only to heal his country of the wounds left on it after all its struggles, which had cemented the union of the several kingdoms, in calling them all to the common defence under a single chief placed above them by reason of his conspicuous ability. After the war with the Danes, Alfred, who had merely assumed the title of King of Wessex, had added to his states Mercia, Wales, and Kent. It was a kingdom composed of incongruous elements; but Alfred understood the management of them by reason of his far-seeing wisdom. In Mercia, originally peopled by the English, he established a viceroy chosen from their royal family, the Ealderman, or duke Ethelred, and gave him his own daughter in marriage. When Ethelred died, after having faithfully served his father-in-law, the Mercians themselves placed in the hands of his widow Ethelfleda the reins of government. {51} Kent already belonged to Alfred. Its unhappy inhabitants, subject more than any others to the Danish invasions, had displayed the most passionate affection and gratitude towards the prince who had effected their deliverance. The Welsh chiefs swore allegiance to him. Alfred established one of them, Amorant, as viceroy of Wales, leaving him thus all his prerogatives and full command over his subjects. While he was thus organizing his Saxon kingdom, Alfred was maintaining firm and friendly relations with the Danish kingdom, which he had allowed to be established near to his own. The propagation of Christianity amongst the pagans was his principal means of effecting the fusion of the races, which he foresaw and which he hoped ardently to see accomplished, but which he could not completely finish during his own lifetime. Some laws were already in force and respected by both races: the crime of murder was punished in the same manner in each state, and Alfred caused the people to rigorously respect the treaties which bound them together; the pirates of East Anglia who came to pursue their ravages along the coasts, being hanged without mercy. The Danes established in England had already become Englishmen in the eyes of Alfred, and were compelled to observe the laws of the English population.
