What role did Odysseus play when sneaking in the city of Troy?

Odysseus played a crucial role in the Greek strategy to infiltrate the city of Troy by devising the plan of the Trojan Horse. He suggested constructing a large wooden horse, hiding Greek soldiers inside, and leaving it at the gates of Troy as a supposed offering of peace. The Trojans brought the horse into the city, believing they had won the war, which allowed Odysseus and his men to emerge at night and open the gates for the rest of the Greek army, leading to the fall of Troy. His cunning and strategic thinking were pivotal to the Greeks' success in the Trojan War.
