Beowulf plunges into the horrible place, while his companions wait for him oh the shore. For a long time he sinks through the flood; then, as he reaches bottom, Grendel's mother rushes out upon him and drags him into a cave, where sea monsters swarm at him from behind and gnash his armor with their tusks. The edge of his sword is turned with the mighty blow he deals the _merewif_; but it harms not the monster. Casting the weapon aside, he grips her and tries to hurl her down, while her claws and teeth clash upon his corslet but cannot penetrate the steel rings. She throws her bulk upon him, crushes him down, draws a short sword and plunges it at him; but again his splendid byrnie saves him. He is wearied now, and oppressed. Suddenly, as his eye sweeps the cave, he catches sight of a magic sword, made by the giants long ago, too heavy for warriors to wield. Struggling up he seizes the weapon, whirls it and brings down a crashing blow upon the monster's neck. It smashes through the ring bones; the _merewif_ falls, and the fight is won. The cave is full of treasures; but Beowulf heeds them not, for near him lies Grendel, dead from the wound received the previous night. Again Beowulf swings the great sword and strikes off his enemy's head; and lo, as the venomous blood touches the sword blade, the steel melts like ice before the fire, and only the hilt is left in Beowulf's hand. Taking the hilt and the head, the hero enters the ocean and mounts up to the shore. Only his own faithful band were waiting there; for the Danes, seeing the ocean bubble with fresh blood, thought it was all over with the hero and had gone home. And there they were, mourning in Heorot, when Beowulf returned with the monstrous head of Grendel carried on a spear shaft by four of his stoutest followers. In the last part of the poem there is another great fight. Beowulf is now an old man; he has reigned for fifty years, beloved by all his people. He has overcome every enemy but one, a fire dragon keeping watch over an enormous treasure hidden among the mountains. One day a wanderer stumbles upon the enchanted cave and, entering, takes a jeweled cup while the firedrake sleeps heavily. That same night the dragon, in a frightful rage, belching forth fire and smoke, rushes down upon the nearest villages, leaving a trail of death and terror behind him. Again Beowulf goes forth to champion his people. As he approaches the dragon's cave, he has a presentiment that death lurks within: Sat on the headland there the warrior king; Farewell he said to hearth-companions true, The gold-friend of the Geats; his mind was sad, Death-ready, restless. And Wyrd was drawing nigh, Who now must meet and touch the aged man, To seek the treasure that his soul had saved And separate his body from his life.[10]
