The brave men, springing up all round, seized their swords and would gladly have helped their lord, but there was no one but Beowulf could harm Grendel.
"So they fought, till at last Beowulf tore away Grendel's hand and arm, and the monster fled away howling into the darkness.

Over the moor he rushed till he came to his bog, and there he sank down into the middle of the bog, wailing and shrieking like one whose last hour was come.
Then there was great rejoicing at Heorot, the palace, and King Hrothgar, when he saw Grendel's hand which Beowulf had torn away, embraced him and blessed him, and he and all his friends were laden with splendid gifts.
"But all was not over yet.

When the next night came, and Hrothgar's men and Beowulf's men were asleep together in the great hall, Grendel's horrible mother, half a woman and half a wolf, came rushing to the palace and while they were all asleep she carried off one of Hrothgar's dearest friends--a young noble whom he loved best of all his nobles.

And she killed him, and carried his body back to the bog.

Then the next morning there was grief and weeping in Heorot; but Beowulf said to the king, 'Grieve not, O king! till we have found out Grendel's mother and punished her for her evil deeds.
