That led Agras to seek cooperation with the leaders of the Bulgarian forces of the area against the Turks and a meeting was arranged on June 3, 1907 between Agras and his opponent, Captain Zlatan, near the town of Aghia Foteini, 10 km north of Naoussa. According to their agreement each group would be unarmed. In the event, the Bulgarians came armed and Agras, with his close friend Mingos were arrested by Zlatan and later hanged on June 7 outside the village of Tekhovo. The news of his death shocked the local Greek population and his fellow fighters who continued his work and eventually managed to predominate in the area of Giannitsa Lake, after the decisive victory of Captain Amyntas against Zlatan on June 30 in Xeroleivado. Tellos Agras is considered to be a martyr of the Greek Struggle of Macedonia and one of the most important and effective band leaders of it. He and his exploits are better known through the pages of the novel "Ta Mystika tou Valtou" ("The Secrets of the Marsh"), written by Penelope Delta.
