The terrible storm released by the men carried them to the island of Circe the Enchantress. Hermes knew that this would cause trouble and gave Odysseus a flower to protect him from her charms.
The men split into two parties to search the island. Eurylochus led one group, Odysseus the other. Eurylochus' group met up with Circe, she made them all welcome and gave them food. Eurylochus stayed outside fearing some trick. Circe had mixed a drug with their wine and she turned them all to pigs.
Odysseus went to the house to see what had happened. He saw Circe and pleaded with her to let his men free. Because she could not bewitch him she knew who he was and set the men free. They all stayed with Circe for a whole year.
When they tore themselves away from Circe she warned them of great danger to come.
