The feast over, Hrothgar escorts his guest to the palace, where he is to rest that night, leaving his own men to guard Heorot, for all feel confident Grendel has been too sorely wounded ever to appear again. But, while the warriors sleep peacefully, the giant's mother--an equally hideous monster--comes into the hall, secures her son's gory arm which hangs there as a trophy, and bears away Aeschere, one of the king's friends. On learning of this loss on the morrow, Hrothgar is overcome with grief, and Beowulf, hearing his lamentations, suddenly appears to inquire what has occurred. On learning the ghastly news, he volunteers to complete his work and avenge Aeschere by attacking Grendel's mother in her own retreat. But, knowing the perils he is facing, he makes his arrangements in case he should never return, before following the bloody traces left by the monsters. Then he hastens to the pool, where he finds Aeschere's head set aloft as a trophy! Gazing down into the depths, Beowulf now perceives the waters are darkly tinged with the monster's blood, but nevertheless plunges boldly into their depths, where he swims about a whole day seeking Grendel's retreat. Guided at last by a phosphorescent gleam, our hero finally reaches a cave, after slaying on the way a number of monsters sent to check his advance. On nearing the giants' den, a strong eddy suddenly sweeps him within reach of Grendel's mother, who, clutching him fast, flings him on the floor, and is trying to find a joint in his armor, so as to kill him with her knife, when Beowulf, snatching a sword hanging from a rocky projection, deals her so fierce a blow that he severs her head from its trunk. Then he saw amid the war-gems a weapon of victory, An ancient giant-sword, of edges a-doughty, Glory of warriors: of weapons 'twas choicest, Only 'twas larger than any man else was Able to bear in the battle-encounter, The good and splendid work of the giants. He grasped then the sword-hilt, knight of Seyldings, Bold and battle-grim, brandished his ring-sword, Hopeless of living hotly he smote her, That the fiend-woman's neck firmly it grappled, Broke through her bone-joints, the bill fully pierced her Fate-cursèd body, she fell to the ground then: The hand sword was bloody, the hero exulted. The brand was brilliant, brightly it glimmered, Just as from heaven gem-like shineth The torch of the firmament. The blood from this monster, pouring out of the cave, mingles with the waters without, which begin to seethe and bubble in so ominous a way that Hrothgar and his men, exclaiming Beowulf is dead, sadly depart. The hero's attendants, however, mindful of orders received, linger at the side of the mere, although they cherish small hope of ever beholding their master again.
