After Grendel's mother attacks Herot and kills one of the warriors, she takes Grendel's arm as revenge for his death.
Grendel's mother takes only one soldier from Herot as vengeance for her son Grendel's death. She wants to inflict pain and create fear among the people of Herot after the loss of her son. Taking a single soldier can also be seen as a calculated move to emphasize her power and dominance.
