Katsonis, together with Androutsos and Barbitsiotis, built a gun battery at Porto Kagio. He gathered a small army and a navy of eleven ships and attacked Ottoman ships in the area. However, not being able to maintain his ships, he started attacking ships from other countries. Later that year, he sank two French ships, which was the beginning of the end for Katsonis. An Ottoman fleet of thirty ships and a French destroyer attacked Katsonis at Porto Kagio. Katsonis' men fled to land; Katsonis himself escaped to Odessa on one of the ships.
