Andreas Vokos, nicknamed Miaoulis (Greek: Ανδρέας Βώκος Μιαούλης, May 20, 1769 – June 24, 1835), was an admiral and politician who commanded Greek naval forces during the Greek War of Independence (1821–1829).
Miaoula was born in Euboea to an Arvanite family and settled on the island of Hydra east of the Morea and was known among his fellow islanders as a trader in corn who had gained wealth and made a popular use of his money. He had been a merchant captain, and was chosen to lead the naval forces of the islands when they rose against the government of the Sultan. Miaoulis contributed in every way possible to the cause of the resistance against the Turks. He expended the money he had made from his wheat-shipping business during the Napoleonic Wars. Between May 1825 and January 1826, Miaoula led the Greeks to victory over the Turks in skirmishes off Modon, Cape Matapan, Suda, and Cape Papas.
The islanders had enjoyed some measure of exemption from the worst excesses of the Turkish officials, but suffered severely from the conscription raised to man the Turkish ships; and though they seemed to be peculiarly open to attack by the Sultan's forces from the sea, they took an early and active part in the rising. As early as 1822 Miaoulis was appointed navarch, (Greek: Ναύαρχος) or admiral, of the swarm of small vessels which formed the insurgent fleet. He commanded the expedition sent to take revenge for the massacre of Chios in the same year. He was victorious at the Battle of Nauplia in September.
In 1824, after the conquest of Psara by the Turks, he commanded the Greek forces which prevented the further progress of the Sultan's fleet, though at the cost of the loss of many fire ships and men. But in the same year he was unable to prevent the Egyptian forces from occupying Navarino, though he harassed them with some success. In 1825 he succeeded in carrying stores and reinforcements into Missolonghi, when it was besieged for the second time, though he could not avert its fall. In order to save Missolonghi, he attempted to disrupt the sea communications of the Egyptian forces. In this he failed owing to the enormous disproportion of the two squadrons in the siege and strength of the ships.
