Epeus
Otus was a hero from Kyllini, Elis. He participated in the Trojan War and his commander was Epeus of Elis. According to Homer, in Hector's exit from the Trojan walls, he fought in a drastic battle.
Odysseus' plan to win the war was to build a wooden Trojan horse, have his men hide in it, and wait for them to take his bait. They are successful. It is at night so the Trojans can't fight back and its basically a slaughter-fest, not a war.
