According to the story, the Greeks built a giant wooden horse and left it outside the gates of Troy as a peace offering. The Trojans, believing that the horse was a gift, brought it inside the city walls. Unbeknownst to the Trojans, the horse was filled with Greek soldiers who emerged at night and opened the city gates to the rest of the Greek army. This allowed the Greeks to enter and sack the city of Troy.
The plan involving the Trojan Horse was a brilliant example of military strategy and deception, and it has become a famous and enduring story from Greek mythology.
