Final answer:
Nestor was an advisory figure whose wisdom and experience aided the Achaeans' strategic decision-making and morale during the Trojan War.
Step-by-step explanation:
Nestor, the legendary Mycenaean hero and king of Pylos, played a primarily advisory and supportive role in the Achaean victory during the Trojan War. While not a frontline warrior like Achilles or Ajax, Nestor was respected for his wisdom, experience, and tactical insights which bolstered the morale and strategic planning of the Achaean forces.
As seen in classical literature, such as Homer's The Iliad, Nestor advised the Greek commanders and sometimes mediated disputes among them, using his eloquent speech to encourage and guide the younger warriors. His presence symbolized the connection with a heroic past and provided stability during the long and arduous siege of Troy.
