The war went on for ten years swinging to one side and then the other. Some of the leading fighters were Achilles, Paris, and Hector. The Greeks won by building a big wooden horse, which we now call the Trojan Horse. Greek soldiers hid inside the horse, and others put the horse on the shore and left in their boats. The Trojans saw the horse and thought that the Greeks had given up and left. They thought the horse was a gift in their honour. They dragged the horse into Troy and celebrated their victory. When night fell, the Greeks hiding inside the horse opened the city gates and set fire to the houses. The Greeks who had left in their boats had just pretended to leave, to trick the Trojans. They returned and won the war. The trick was thought up by Odysseus, King of the small island of Ithaca.
