Athanasios Diakos (real name: Athanasios Grammatikos) was the central figure in the detonation and development of the Revolution in Eastern Central Greece, accomplishing many successful attacks against the Ottomans in the region. Specifically, he had managed to seize Livadia, Thebes, and Atalanti. At the Battle of Alamana (April 23, 1821), Diakos and a few men tried to resist Kiose Mehmet and Omer Vryonis, who were instructed to suppress the Revolution in Roumeli, and then move to the Peloponnese. After fighting a heroic battle, Diakos was wounded and got arrested. On the next day, he was transferred to Lamia, where he refused to collaborate with the Ottomans. So, the Ottomans decided an exemplary punishment for him, death by impalement.
