Ali Pasha and after negotiations they all signed an agreement, which stipulated that in the upcoming revolt in Greece they would not send their troops against the rebels, but revolt in favor of Ali Pasha. Greek Revolution In May 1821, Omer Vrioni, now the commander of the Ottoman army, advanced with 8,000 men, after crushing the resistance of the Greeks at the river of Alamana and putting Athanasios Diakos to death, headed south into the Peloponnese to crush the Greek uprising. Odysseas Androutsos with a band of 100 or so men took up a defensive position at an inn near Gravia, supported by Panourgias and Diovouniotis and their men. Vrioni attacked the inn but was repulsed with heavy casualties of over 300 dead.

However, he was soon restored and kept his command in Eastern Central Greece. In September 1822, at the insistence of the Athenian municipal authorities, Androutsos, Yannis Gouras, and Yannis Makriyannis took control of the Acropolis of Athens, which had been surrendered in June. To ensure the occupation he had a bastion built to protect the ancient Klepsydra spring, which had just been rediscovered by chance on
