Who was the spy who convinced trojans to bring wooden horse into troy?

The spy who convinced the Trojans to bring the wooden horse into Troy was Sinon. He was a Greek soldier who pretended to be a defector and convinced the Trojans that the wooden horse was a gift from the gods. He also told them that the Greeks had abandoned their camp and sailed away, leaving the wooden horse behind. The Trojans believed Sinon and brought the wooden horse into Troy, which led to their defeat.
