Odysseus had the idea of building a big wooden horse and filling it with Greek soldiers and having the rest of the greeks leave. This way the Trojans will think that they have won, and they will bring the horse inside the gates, thinking that it is a gift.
So the rest of the Greeks left, making the Trojans think that the Greeks surrendered
They were suspicious at first, but then realized that it was a gift when they saw the greeks leaving. But little did they know that there were greeks inside the belly of the horse.
Oh No, They tricked us!
Once night fell, all of the Greek soldiers came out of the wooden horse, one by one.
Then they let in the rest of the Greek soldiers, which had only pretended to go back to Greece
Come on, let's go win this war!
The Greeks officially defeated Troy, by setting it on fire. The Greeks had won!
