The Trojan War

I don't really know much about the Trojan war. but what i do know is that there was a big horse. There was also people inside the horse I think. I learned that there was a big wall surrounding troy I learned that there was a person named Helen. Helen started the the whole war. Paris was chosen to choose someone to give the apple to, he chose Aphrodite offer and he got Helen but they had to steal her so that started the war.
