They had not lost courage, however, and four days later they returned to give battle once more to their enemies; the Danes had already issued forth from their intrenchments, but Ethelred was still in his tent, attending holy mass, and would not hurry to the scene of battle, in spite of urgent messages from Alfred. The latter, therefore, attacked their opponents single-handed, opposite a little tree which the Danes had chosen as a rallying-spot. The Saxons fought with the fury of despair; Ethelred soon came to support his brother, and the Danes, beaten upon the great plain of Assendon, took to flight; but only to return a fortnight afterwards, their number swelled by the reinforcements which were continually arriving by sea. {42} Wessex alone had sustained eight battles in one year; her resources were becoming exhausted in such an unequal struggle; Ethelred, wounded, had just died, and Alfred found himself alone at the age of twenty-two years (871), subject to a peculiar illness which had succeeded to a slow fever of his boyhood, and of which the attacks would frequently bring him to the very verge of the grave. His men and his resources exhausted, a ninth and unfortunate battle completely disabled him; he was compelled to sue for peace. The Danes willingly consented to his proposal; there were other princes to vanquish, other territories to conquer, less valiantly defended than Wessex, on which they proposed to revenge themselves when it should stand alone in its resistance to them. In 875 they had finished their conquest; Wessex alone still preserved its independence, and three Danish kings who had passed the winter at Cambridge embarked secretly, by night, to attack the coast of Dorset. Vainly did Alfred strive to resist his enemies by sea; his ships were beaten, and soon the long line of incendiarism and murder which always marked the progress of the Danes extended as far as Wareham. This was past endurance, and Alfred, stricken down on a sick-bed, asked for and obtained peace at the price of gold. The Danes retired after having sworn friendship upon some relics brought by the Christian king and on their sacred bracelets steeped in the blood of their victims, exchanging hostages, whose fate they troubled themselves very little about. The very night after peace was concluded, the Saxon horsemen were destroyed and cut up piecemeal by the Danes, who took possession of their horses in order to make a raid into the interior of the country. The remonstrances of Alfred were powerless to stop these disastrous expeditions, so easy for an enemy who threatened the country from all sides. {43}
