.|left After the failure of the uprising in Wallachia, he went to the
Morea in the
Peloponnese, where the
Greek War of Independence had just broken out, as representative of the Filiki Etaireia and his brother, Alexandros. He was among the most prominent Phanariote leaders in the early stages of the revolt, though he was much hampered by local chiefs and the civilian element headed by
Alexandros Mavrokordatos; He took part in the
Siege of Tripolitsa, of
Nafplion, and the
Battle of Dervenakia, securing Greek control of Morea. On 15 January 1822, he was elected president of the
First National Assembly at Epidaurus. However, due to the failure of his campaign in central Greece, and his failure to obtain a commanding position in the
national convention of Astros, he was forced to retire in 1823. After the landing of
Ibrahim at Morea, he took part in the defence of Nafplion in the
Battle of the Lerna Mills. In 1828, he was appointed in the newly established regular army by
Ioannis Kapodistrias as commander of troops in eastern Greece. On 25 September 1829, he successfully compelled Aslan Bey to capitulate at the Pass of Petra (
Battle of Petra), thus ending active operations of the war. ==Personal life==
