Ethelbert died in 866 and was succeeded by Ethelred. In 868 Alfred married Elswitha, the daughter of Ethelred Mucil of Mercia. Meanwhile the Danes had resumed their predatory excursions, and in the winter of 870-871 Ethelred accompanied by Alfred attacked them at Reading, but after an initial victory was repulsed. Four days later, Ethelred and Alfred with their forces were attacked on Ashdown near White Horse Hill; after a heavy slaughter the Danes were out to flight. The Danes, however, reinforced by Guthrum with new troops from over the sea, within a fortnight resumed offensive operations, and at Merton, two months later, Ethelred was mortally wounded. He died almost immediately after the battle, and "at the age of twenty-three Alfred ascended the throne of his fathers, which was tottering, as it seemed, to its fall.") THOMAS HUGHES The throne of the West Saxons was not an inheritance to be desired in the year 871, when Alfred succeeded his gallant brother. It descended on him without comment or ceremony, as a matter of course. There was not even an assembly of the witan to declare the succession as in ordinary times. With Guthrum and Hinguar in their intrenched camp at the confluence of the Thames and Kennet, and fresh bands of marauders sailing up the former river, and constantly swelling the ranks of the pagan army during these summer months, there was neither time nor heart among the wise men of the West Saxons for strict adherence to the letter of the constitution, however venerable. The succession had already been settled by the Great Council, when they formally accepted the provisions of Ethelwulf's will, that his three sons should succeed, to the exclusion of the children of any one of them. The idea of strict hereditary succession has taken so strong a hold of us English in later times that it is necessary constantly to insist that our old English kingship was elective. Alfred's title was based on election; and so little was the idea of usurpation, or of any wrong done to the two infant sons of Ethelred, connected with his accession, that even the lineal descendant of one of those sons, in his chronicle of that eventful year, does not pause to notice the fact that Ethelred left children. He is writing to his "beloved cousin Matilda," to instruct her in the things which he had received from ancient traditions, "of the history of our race down to these two kings from whom we have our origin." "The fourth son of Ethelwulf," he writes, "was Ethelred, who, after the death of Ethelbert, succeeded to the kingdom, and was also my grandfather's grandfather. The fifth was Alfred, who succeeded after all the others to the whole sovereignty, and was your grandfather's grandfather." And so passes on to the next facts, without a word as to the claims of his own lineal ancestor, though he had paused in his narrative at this point for the special purpose of introducing a little family episode.
