In 1466 Kosača died, having deposited his will at Ragusa. By its terms his estates were divided between his three sons, Stephen, Vladislav, and Vlatko. To the first he also left his crown, some plate and jewels, and 30,000 ducats, to the third 30,000 ducats, to his widow Cecilia 1000 ducats, some plate, brocades, and robes; the rest of his personalty was to be divided equally among his three sons, save 10,000 ducats for his soul.[420] But their possessions were constantly menaced by the Turks, and the youngest brother became a renegade and took the name of Achmed Beg. The other two soon quarrelled among themselves, and each asked for Turkish assistance. In 1469 Hamsa Beg raided Ragusan territory, and an attack on the town was momentarily expected. A second raid was made in 1470, and Postranja and Canali were laid waste, the castle of Soko alone holding out. The Ragusan merchants in Trebinje were also plundered. As Hamsa refused to hear reason, the garrison was increased, the galleys armed, and the moat before the Porta Pile dug.[421] At this time Počitelj was being besieged. The Ragusans had been trying to induce the Sultan to reduce the tribute from 5000 to 3000 ducats, stating that the constant troubles in Slavonia and Servia had made them very poor. As Mohammed was engaged in the Persian war, his vizirs agreed to the reduction, but when he returned he not only insisted on the remaining 2000 being paid, but raised the sum to 8000.[422] There was nothing for it but to pay, as Turkish karaulas (block-houses) were only two miles from the gates, and an attack was feared at any moment. But it was not paid for nothing, for the Ragusans obtained many new privileges; moreover, the increase was in part due to the fact that the Turks were the successors to various native princes whom they had dispossessed, and to whom the Republic had formerly paid tribute. The Pope renewed the exemption to trade with the Infidel. The one danger was that the Turks should suddenly desire to capture the city, as on more than one occasion they had been on the point of doing. It required all the skilful diplomacy of the Senate to avoid this contingency.
