"What will happen to the wound?". The oracle responded, "he that wounded shall heal". The Achaean fleet then set sail and was scattered by a storm. Achilles landed in Skyros and married Deidamia. A new gathering was set again in Aulis. Telephus went to Aulis, and either pretended to be a beggar, asking Agamemnon to help heal his wound, or kidnapped Orestes and held him for ransom, demanding the wound be healed. Achilles refused, claiming to have no medical knowledge. Odysseus reasoned that the spear that had inflicted the wound must be able to heal it. Pieces of the spear were scraped off onto the wound, and Telephus was healed. Telephus then showed the Achaeans the route to Troy. Some scholars have regarded the expedition against Telephus and its resolution as a derivative reworking of elements from the main story of the Trojan War, but it has also been seen as fitting the story-pattern of the "preliminary adventure" that anticipates events and themes from the main narrative, and therefore as likely to be "early and integral". Second gathering Eight years after the storm had scattered them, the fleet of more than a thousand ships was gathered again. When they had all reached Aulis, the winds ceased. The prophet Calchas stated that the goddess Artemis was punishing Agamemnon for killing either a sacred deer or a deer in a sacred grove, and boasting that he was a better hunter than she. The only way to appease Artemis, he said, was to sacrifice Iphigenia, who was either the daughter of Agamemnon and Clytemnestra, or of Helen and Theseus entrusted to Clytemnestra when Helen married Menelaus. Agamemnon refused, and the other commanders threatened to make Palamedes commander of the expedition. According to some versions, Agamemnon relented and performed the sacrifice, but others claim that he sacrificed a deer in her place, or that at the last moment, Artemis took pity on the girl, and took her to be a maiden in one of her temples, substituting a lamb. Hesiod says that Iphigenia became the goddess Hecate. The Achaean forces are described in detail in the Catalogue of Ships, in the second book of the Iliad. They consisted of 28 contingents from mainland Greece, the Peloponnese, the Dodecanese islands, Crete, and Ithaca, comprising 1186 pentekonters, ships with 50 rowers. Thucydides says that according to tradition there were about 1200 ships, and that the Boeotian
