In Book XVIII of the Iliad, Polydamas advises the Trojans to retire from the battlefield after the death of Patroclus.
Hector, however, overrules Polydamas, leaving the army in the field when Achilles ends his feud with Agamemnon and rejoins the Achaean forces.
In Book XV, after killing Mecistus and Otus, he is attacked by Meges, but Apollo saves him, causing him to dodge at the last moment.
[3] Homer gives no foreshadowing of Polydamas's final fate, nor is he mentioned in most of the later poems dealing with the aftermath of the war, leaving the reader to infer that he perished in the general slaughter after the fall of Troy to the Greek forces.
In Quintus Smyrneaus' story, Polydamas actually suggests that instead of attacking or fleeing, the Trojans should just give Helen back to the Greeks.
