Agamemnon and his powerful host set sail from Aulis; but being ignorant of the locality and the direction, they landed by mistake in Teuthrania, a part of Mysia near the river Caicus, and began to ravage the country under the persuasion that it was the neighborhood of Troy. Telephus, the king of the country, opposed and repelled them, but was ultimately defeated and severely wounded by Achilles. The Greeks, now discovering their mistake, retired; but their fleet was dispersed by a storm and driven back to Greece. Achilles attacked and took Scyrus, and there married Deidamia, the daughter of Lycomedes. Telephus, suffering from his wounds, was directed by the oracle to come to Greece and present himself to Achilles to be healed, by applying the scrapings of the spear with which the wound had been given; thus restored, he became the guide of the Greeks when they were prepared to renew their expedition.
The armament was again assembled at Aulis, but the goddess Artemis, displeased with the boastful language of Agamemnon, prolonged the duration of adverse winds, and the offending chief was compelled to appease her by the well-known sacrifice of his daughter Iphigenia. They then proceeded to Tenedos, from whence Odysseus and Menelaus were dispatched as envoys to Troy, to redemand Helen and the stolen property. In spite of the prudent counsels of Antenor, who received the two Grecian chiefs with friendly hospitality, the Trojans rejected the demand, and the attack was resolved upon. It was foredoomed by the gods that the Greek who first landed should perish: Protesilaus was generous enough to put himself upon this forlorn hope, and accordingly fell by the hand of Hector.
Meanwhile, the Trojans had assembled a large body of allies from various parts of Asia Minor and Thrace: Dardanians under Æneas, Lycians under Sarpedon, Mysians, Carians, Mæonians, Alizonians, Phrygians, Thracians, and Pæonians. But vain was the attempt to oppose the landing of the Greeks: the Trojans were routed, and even the invulnerable Cyncus, son of Poseidon, one of the great bulwarks of the defense, was slain by Achilles. Having driven the Trojans within their walls, Achilles attacked and stormed Lyrnessus, Pedasus, Lesbos, and other places in the neighborhood, twelve towns on the sea-coast, and eleven in the interior: he drove off the oxen of Æneas and pursued the hero himself, who narrowly escaped with his life: he surprised and killed the youthful Troilus, son of Priam, and captured several of the other sons, whom he sold as prisoners into the islands of the Ægean. He acquired as his captive the fair Briseis, while Chryseis was awarded to Agamemnon; he was, moreover, eager to see the divine Helen, the prize and stimulus of this memorable struggle; and Aphrodite and Thetis contrived to bring about an interview between them.
At this period of the war the Grecian army was deprived of Palamedes, one of its ablest chiefs. Odysseus had not forgiven the artifice by which Palamedes had detected his simulated insanity, nor was he without jealousy of a rival clever and cunning in a degree equal, if not superior, to himself; one who had enriched the Greeks with the invention of letters of dice for amusement of night-watches as well as with other useful suggestions. According to the old Cyprian epic, Palamedes was drowned while fishing by the hands of Odysseus and Diomedes. Neither in the
