At length they reached a great cliff, but there was no opening to be seen large enough to serve as a door. A few cracks might be noticed here and there in the stone, so small that only a dwarf or a lizard could have crept in; certainly not a man in armour, and still less a giant. Hildebrand thought that a bit of the rock might perhaps be fitted into the cliff instead of a door. He tried to shake and loosen any projecting piece of the cliff that he could clutch. His efforts were not in vain. An enormous block of stone stirred and rocked beneath his hands, and just as Dietrich came to his assistance, it fell thundering into the valley below. The sunlight penetrated the darkness of a deep cavern, in the background of which a great fire was burning. Grim was lying on a bed of bear and wolf skins close to the flames. Wakened by the falling rock, he raised himself on his elbow, and perceiving the warriors’ approach, looked about for his sword; not finding it, he snatched up a burning log, and rushed upon Dietrich. His blows sounded like claps of thunder, and fell as thick as hail; it was only the young warrior’s nimbleness that saved his life, which was endangered not only by the force of the blows, but by the smoke and the burning sparks that flew from the log. Hildebrand would have gone to his pupil’s assistance had not the latter forbidden him. And indeed he soon had enough to do to defend himself, for the giantess now appeared, and catching Hildebrand up in her arms, held him tight. It was a deadly embrace. The warrior could not breathe. He struggled in vain to free himself from the sinewy arms that held him. At last the giantess threw him on his back, pressing his hands and arms as though in a vice, and making the blood spirt from under his nails. She looked about for a rope with which to bind and hang him. Hildebrand called to his companion to help him in his need. Dietrich seeing his friend’s danger leaped over the giant’s weapon with a despairing spring, and at the same time seizing his sword in both hands, split the monster’s head from the crown to the collar-bone. Then turning upon the giantess, he slew her after a short but sharp engagement. Hildebrand now staggered to his feet, and said that from henceforth he would regard his former pupil as his master, because that woman had been harder to deal with than any foe he had ever met before. Dietrich and Hildebrand took the treasure they found hidden away in a side cave, as their meed of victory, and brought it home to Bern. King Dietmar rejoiced in the glory of his heroic son, whose name had become famous in every land; but he did not live long after these events. He died loved and honoured by all. When Dietrich ascended the throne, he gave his young brother Diether into Hildebrand’s charge, begging his friend to teach the boy to be a hero and a worthy scion of his noble race.
