This was the situation when, at the age of twenty-two, Alfred, afterward to be called the Great, ascended to the throne. Nor could he well have become king at a less propitious moment. For, with the whole of the north and east now firmly in their grasp, the Danes were already pressing upon Wessex. A battle fought almost immediately after his accession to the throne was rather in the nature of a draw than a victory; and, although the enemy withdrew for a time, a few years later found Alfred at bay in the {xvi} marshes of West Somerset, with the Danes overrunning and apparently in secure possession of some of the most fertile parts of his kingdom. Fortunately for his people, however, Alfred, for all his refinement, his love of culture, and cosmopolitan boyhood, had inherited in full measure the stubborn Saxon refusal to accept either slavery or defeat; and, a few months later, rallying to his standard an army of Hampshire, Wiltshire, and Somersetshire men, he inflicted upon the Danes, at the battle of Ethandun, the severest defeat that they had yet sustained. By the treaty of Wedmore in 878, he secured the integrity of the south and west, recognizing that, in the north and east, the Danish element was not only too strong to be expelled, but was already becoming welded, not wholly to its disadvantage, with the national life. He agreed, therefore, for his own part, to recognize the Danish influence upon the other side of Watling Street, at the same time persuading its representative leaders to forsake their paganism and embrace Christianity. Against further aggression, however, from abroad, he determined at all costs to protect the Island; and he was the earliest of his line to realize that his country's first defense was the sea that washed its shores. Already, in 875, he had been the victor in Swanage Bay over a small but strong fleet of pirates; and, after the peace of Wedmore, he set himself to the serious construction and effective distribution of a fleet of war. With no lack of raw material, with good craftsmen, and with a maritime population needing nothing but initiative, he built a navy that, in respect of {xvii} _personnel_ no less than in technical equipment, soon outclassed that of the Danes. Distributed round the coast, he had, according to varying accounts, from 120 to 300 warships; and, behind this bulwark, for the next fifteen years, England achieved an almost miraculous degree of progress. In 896, after a considerable struggle, another attempted invasion was crushed, and Alfred's fleet, grown in strength and experience, extinguished the recurrence of piracy that had accompanied it. Merciful in character and tolerant in statesmanship, toward these pirates he showed no clemency, and, when he died in 901, he left a country prosperous and at peace and with its sea-boards inviolate.
