The Senate sent a squadron out under Stefano Sorgo to capture all Venetian or Cattarine ships found in South Dalmatian waters,[312] while envoys went to Cattaro to stir up the people to rebel against Venice and return to Hungarian allegiance. But the Cattarini, still fearing the Venetians, at first refused. Then a joint Genoese and Ragusan fleet made a demonstration against the town, and the authorities promised to raise the Hungarian standard on a certain date. But they failed to do so, and intrigued instead with the King of Bosnia against Ragusa, plundered Ragusan grain ships, and captured the sentinels guarding the approaches to the city on the Monte Sergio. After the total defeat of the Venetian fleet off Pola in May the Ragusans pursued their operations against Cattaro by land and sea with renewed vigour, and by June 26 the town had once more returned to Hungarian allegiance.[313] Meanwhile the Genoese had carried the war almost to the very gates of Venice, and were besieging Chioggia. A Ragusan contingent under Matteo Giorgi was of great assistance to them in the siege, owing to Giorgi’s knowledge of the use of artillery,[314] and, according to Razzi, he would have prevented the blockade of the Genoese fleet, which was executed, by closing the harbour with sunken boats, if only his advice had been followed.[315] On the defeat of the Genoese the Ragusan galleys managed to escape, and saved a number of the fugitives whose vessels had been sunk (June 24, 1380). Desultory fighting continued for a few months longer, in which the Ragusan galleys took part, and in 1381 peace was signed at Turin. Although in the end the Genoese had been defeated, Venice was by no means victorious, and had to confirm her renunciation of Dalmatia, much to the satisfaction of Ragusa.
