Trojan Horse Overview The story of Trojan Horse is that in ancient Greek legend, the Greek allied forces besieged Trojan Horse for a long time, so they pretended to retreat, leaving a huge hollow Trojan Horse. The defenders of Troy didn't know what to do, so they took Troy's horses to the city as trophies. In the dead of night, Greek soldiers hiding in Trojan horse's belly opened the gate, and Troy fell. Later generations often use the allusion of "Trojan horse" to describe the activities of laying an ambush in the enemy camp. Trojan horse is also the name of a famous computer Trojan horse program. Legend of Trojan Horse According to ancient Greek legend, Paris, the prince of Troy, visited Greece and lured Queen Helen away, so the Greeks went on an expedition to Troy. Nine years after the siege, in 10, the Greek general Odysseus put forward a plan to ambush a group of warriors in the belly of a huge wooden horse, put them outside the city and pretend to retreat. The Trojans thought that the enemy soldiers had retreated, so they moved the Trojan horse into the city as a trophy. At night, the warriors who were ambushed in the wooden horse jumped out to open the gate, and Greek soldiers swarmed in and captured the city.
