In due time Beowulf himself became King, and well he governed the land for fifty years. Then trouble came.
A slave, fleeing from his master, stumbled by an evil chance into the den of a dragon. There he saw a dazzling hoard of gold, guarded by the dragon for three hundred winters. The treasure tempted him, and he carried off a tankard of gold to give to his master, to make peace with him.
The dragon had been sleeping, now he awoke, and sniffed the scent of an enemy along the rock. He hunted diligently over the ground; he wanted to find the man who had done the mischief in his sleep. In his rage he swung around the treasure mound, dashing into it now and again to seek the jewelled tankard. He found it hard to wait until evening came, when he meant to avenge with fire the loss of his treasure.
Presently the sun sank, and the dragon had his will. He set forth, burning all the cheerful homes of men: his rage was felt far and wide. Before dawn he shot back again to his dark home, trusting in his mound and in his craft to defend himself.
Now Beowulf heard that his own home had been burnt to the ground. It was a great grief to him, almost making him break out in a rage against Providence. His breast heaved with anger.
He meant to rid his country of the plague, and to fight the dragon single handed. He would have thought it shame to seek him with a large band, he who, as a lad, had killed Grendel and his kin. As he armed for the fray, many thoughts filled his mind; he remembered the days of his youth and manhood. "I fought many wars in my youth," he said, "and now that I am aged, and the keeper of my people, I will yet again seek the enemy and do famously."
He bade his men await him on the mountain-side. They were to see which of the two would come alive out of the tussle.
There the aged King beheld where a rocky archway stood, with a stream of fire gushing from it; no one could stand there and not be scorched. He gave a great shout, and the dragon answered with a hot breath of flame. Beowulf, with drawn sword, stood well up to his shield, when the burning dragon, curved like an arch, came headlong upon him. The shield saved him but little; he swung up the sword to smite the horrible monster, but its edge did not bite. Sparks flew around him on every side; he saw that the end of his days had come.
His men crept away to the woods to save their lives. One, and one only,
Wiglaf by name, sped through the smoke and flame to help his lord.
"My Lord Beowulf!" he cried, "with all your might defend life, I will support you to the utmost."
