In accordance with this prophecy, Odysseus and Diomedes go to Lemnos to bring back Philoctetes, who is healed of his wound by Machaon. Philoctetes then fights Paris in single combat and kills him. After Paris's death, Helenus and Deiphobus fight over Helen. Deiphobus wins and marries her. The defeated Helenus angrily abandons Troy in spite and moves to Mount Ida. Odysseus, who is a recurrent figure of interest in the "Little Iliad", ambushes Helenus and captures him; Helenus then reveals three new prophecies concerning the preconditions for the Greeks' conquest of Troy, notably, that the city will not fall while it harbours the Palladium. The other two conditions are that the bones of Pelops are recovered from Pisa, a rival of Elis, and that Neoptolemus, son of Achilles, is brought into the war. While a ship of Mycenaeans sail to Pisa to bring back the bones of Pelops, Odysseus brings Achilles's son Neoptolemus to Troy, gives him his father's armor. Achilles's ghost appears to him. When the Trojan ally Eurypylus dominates the field in battle, Neoptolemus kills him. Odysseus and Diomedes go into Troy disguised as beggars, where Helen recognises them but keeps their secret; they return safely with the Palladium, killing some Trojans on the way. On the goddess Athena's initiative, the Greek warrior Epeius builds the wooden horse, and the Greeks place their best warriors inside it, burn their camp, and withdraw to the nearby island Tenedos. The Trojans, believing that the Greeks have departed for good, breach a section of their city wall to bring the horse inside, and celebrate their apparent victory. The emergence of the heroes from the horse, and the Greeks' destruction of Troy, seem not to be recounted in the "Little Iliad", but are left for the "Iliou persis". Nonetheless, a substantial fragment which is securely attributed to the "Little Iliad" describes how Neoptolemus takes Hector's wife Andromache captive and kills Hector's baby son, Astyanax, by throwing him from the walls of the city. The "Little Iliad" does not seem to have been redacted in a single, authoritative version, according to varying accounts of its details that cannot securely be harmonised.
