Around 1770, Haci Osman with 16,000 men besieged the two towers in Kastania. The defenders were Constantine Kolokotronis and Panagiotes Venetsanakis with 150 men and women. The fight lasted for twelve days: most of the defenders were killed, and all prisoners of war were tortured and dismembered. The wife of Constantine Kolokotronis was dressed like a warrior and fought her way out carrying her baby, Theodoros Kolokotronis, the future commander of the Greek War of Independence.[45]
From Kastania, Hasan Ghazi advanced towards Skoutari and laid siege to the tower of the powerful Grigorakis clan. The tower contained fifteen men, who held out for three days until the Turks placed gunpowder in a mine and blew up the overall garrison. By this time, the main Maniot army of 5,000 men and 2,000 women had established a defensive position at which was on mountainous terrain above the town of Parasyros. The entire army was under the command of Exarchos Grigorakis and his nephew Zanetos Grigorakis. The Ottoman army advanced to the plain of Agio Pigada (meaning "Holy Well"). They sent envoys to the Maniots telling them that Hasan wanted to negotiate. The Maniots knew that if they sent envoys to the Turks, they would be executed by Hassán if the negotiations failed. The Maniots sent six men to discuss the terms.[44]
Six Maniot envoys were sent to Hasan and, without bowing, asked him what he wanted. Hasan's demands entailed the children of ten captains as hostages, all Maniot-held arms, and an annual head-tax to be paid as punishment for supporting the Russians. The Maniots answered Hasan's demands saying, "We prefer to die rather than give to you our guns and children. We don't pay taxes, because our land is poor." Hasan became furious and had the six men decapitated and impaled on stakes so that the Maniots could see them.[46]
After the envoys were killed, the remaining Maniots attacked the Ottomans. The fighting was fierce, and only 6,000 Turks managed to reach Mystras. No one knew exactly how many casualties the Maniots suffered, but the Turks definitively lost 10,000 men.
