Ismarus is a city or island in the story "The Odyssey". There Odysseus and his men go there after the long battle in Troy to party and raid the people over there.
He had to go fight in the battle of Troy.
he had to go to war im troy
Odysseus entered the city of Troy by using a Trojan Horse, a giant replica of a horse, and destroyed Troy from the inside. He wouldn't have been able to if Poseidon didn't send a sea serpent to kill the snitch, who was about to give away Odysseus' position. After Odysseus defeated the city of Troy, he gloated about how he solemnly defeated the town with no help of the Gods. This made Poseidon furious, so he cursed Odysseus and his men so they would go through Hell if they ever sailed again. Eventually all of his men (excluding Odysseus) were either killed by the Cyclops, turned into pigs by the witch, or fell into the endless pit created by Poseidon.
After Odysseus "visits" the cyclops, he and his men go to the Land of the Dead.
Odysseus goes back home because that is where he wants to return after fighting the war at Troy. He has a wife and a child whom he has not seen for many years. Further, the men who are with him wish to return home to Greece as well.
This depends on the context and situation. Men go and return with Odysseus hundreds of times.
Odysseus was curious about the type of men the Cyclops were.
