Jani Beg
As the Grimaldis did not go out at sea to oppose the Republic's galleys, the doge sent the navy to support the island of Chios, then a Genoese colony, which was besieged by Jani Beg, khan of the Golden Horde. The fleet also managed to reconquer the city of Phocea and its important alum mines on September 20, 1346.
