In 1818, the three partners moved to Constantinople to further their cause. There in July, Skoufas fell ill and died leaving Tsakalov as one of the two leaders of the organization. Tsakalov was dedicated to the Greek War of Independence which started in 1821. During the war Tsakalov served as a flag lieutenant to Alexander Ypsilantis, the later leader of Filiki Eteria.
