Ten years the siege of Troy lasted, that mighty struggle that had been kindled by the flame of jealousy of gods and men, and ten years the Trojans resisted the Greeks. On both sides the brave fell in battle and the plain outside of the city of Troy became a waste place, full of dread and death. The hero Achilles, while offering up a sacrifice in the temple of Apollo, was treacherously slain by a poisoned arrow from Paris' bow that pierced his heel. The Greeks made use of the arrows of Hercules in their struggle, but even these proved useless against the strong fortifications of the Trojans. There was a statue of Minerva in the city of Troy called the Palladium. It was said to have fallen from heaven and that as long as it remained in the city Troy could not be taken. So the hero, Ulysses, with a few men, entered Troy in disguise and captured this statute at the risk of their lives, carrying it back to the camp of the Greeks, but Troy still held out and the tenth year of the war drew near a close full of wretchedness and famine. It seemed as if the spell of Helen's beauty, as she leaned from one of the towers of King Priam's castle to cheer the Trojans or descended to pass among their ranks, was their safety. No one, looking on her fair face, remembered hardship or felt fear, although the fated Cassandra wept alone, and was deemed mad because she saw, in her prophetic vision, the fall of the strong battlements of Troy. At last the Greeks despaired of ever subduing Troy by force and they asked Ulysses if any plan occurred to him by which they could subdue the Trojans through strategy. Ulysses unfolded a plan to the generals, and what it was and how it succeeded is one of the strangest stories of all warfare. Acting upon his advice, the Greeks made preparation to abandon the war. Their ships that had waited with folded sails in the harbor, now drew anchor and sailed swiftly away, taking refuge behind a neighboring island. And the Trojans, seeing the encampment before their walls broken for the first time in so many years, and the plain that the enemy's tents had whitened clear, broke into joy and merrymaking such as they had not known for so long. They forgot caution and opened the gates through which the men and women and children flocked out to the plain to make merry and exult over the defeat of the Greeks. There they saw an astounding thing. In the centre of the plain stood a great wooden image of a horse, like an idol, more prodigious than any which the Trojans had ever seen. It was so closely fitted and carved from its mammoth hoofs to its head that no one could detect the joining. A hundred men could have ridden the horse with room for more, but they would never have been able to climb up to its back. At first the people of Troy, gathering around the wooden horse, were afraid of it. Then they made up their minds about it.
