It was at this dismal period that Alfred found shelter in the hut of a swineherd, and, while examining his arrows, allowed the cakes to burn. "Stupid man!" cried the swineherd's wife, unaware of his quality, "you will not take the trouble to prevent my bread from burning, though you're always so glad to eat it." But, ere long, Alfred emerged from his obscure lurking-place, visited the Danish camp disguised as a harper, and, while entertaining the rude Northmen with music and song, became so well acquainted with the situation of affairs that he took immediate steps to restore the old Saxon nationality. Summoning fighting men of the Saxon race from every quarter, Alfred met the Danes in the field, vanquished them in eight battles, and finally reduced them to submission and obedience. After the death of Alfred the Great, who had, after his restoration, reigned with lustre and glory, Ethelstane, pursuing Alfred's conquests, recovered York, crossed the Tweed, defeated the Danes and Cambrians at Bamborough, and brought the whole island under his dominion. For some time after Ethelstane's triumphs, the Saxons were allowed unmolestedly to sow and reap, to buy and sell, to marry and give in marriage. In 994, however, Sweyn, King of Denmark, turned his eyes covetously towards England, where Ethelred the Unready then reigned; and forthwith, in company with Olaf, King of Norway, undertook an expedition. Despairing of opposing the invaders with success, Ethelred bribed them with a large sum of money to retire, and both of them withdrew, after having sworn not again to trouble England. Nevertheless, in 1001, Sweyn, in whom the spirit of the pirate was strong, reappeared; and the Saxon King, seeing no way of getting rid of such a foe except by bribery, agreed to pay an annual tribute, to be levied throughout England under the name of "Dane-gold." Sweyn, to whom an arrangement that was every year to replenish his treasury seemed satisfactory, returned to Denmark. Many Danes, however, remained in England, and conducted themselves with such intolerable insolence that the Saxons projected a general massacre of their unwelcome guests, and fixed on St. Brice's Day, 1002, for the execution of their hoarded vengeance. Ethelred, who, having lost his first wife, Elgira, the mother of Edmund Ironsides, had espoused Emma, sister of the Duke of Normandy, and who deemed himself secure in the alliance of the heir of Rolfganger, unhappily consented to the massacre, and, on the appointed day, the Saxons applied themselves to the work of extermination, little dreaming what would be the consequences.
