In the beginning, this plan was successful and Odysseus and his men managed to establish a strong massacre for the residents of the region. However, they paid no attention to the group of Cicones that came to the city to help their countrymen.
Due to the lack of attention, Odysseus and his men were taken by surprise and suffered a great defeat. Many men died and Odysseus had to flee the city with a heavily reduced crew.
