The Genoese of Galata had good reasons to be dissatisfied with the commercial and naval policy of Cantacuzene, and it was no less their interest than that of their ambitious fellow-countryman to see John V replaced on the throne of his ancestors. They accordingly entered into negotiations with him at Tenedos, and thus Gattilusio could rely upon the co-operation of his compatriots at the capital. On a dark and windy night in the late autumn of 1354 he arrived with the young Emperor off the “postern of the Pathfinding Virgin,” where his Ligurian mother-wit at once suggested a device for obtaining admittance. He had on board a number of oil-jars, which he had brought full from Italy—for he combined business with politics—but which were by this time empty. These he ordered the sailors to hurl against the walls one at a time, until the noise awoke the sleeping sentinels. To the summons of the latter voices shouted from the galleys, that they were merchantmen with a cargo of oil, that one of their ships had been wrecked, and that they were willing to share the remains of the cargo with anyone who would help them in their present distress. At this appeal to their love of gain the guards opened the gate, whereupon some 500 of the conspirators entered, slew the sentries on the adjoining tower, and were speedily reinforced by the rest of the ships’ crews and marines. Francesco, who was throughout the soul of the undertaking, mounted a tower in which he placed the young Emperor with a strong guard of Italians and Greeks, and then ran along the wall with a body of soldiers, shouting aloud: “long live the Emperor John Palaiologos!” When dawn broke and the populace realised that their young sovereign was within the walls, their demonstrations convinced Cantacuzene that resistance would be sanguinary, even if successful. He therefore relinquished the diadem which he could not retain, and retired into a monastery, while John V, accompanied by Francesco and the rest of the Italians, marched in triumph into the palace. The restored Emperor was as good as his word; he bestowed the hand of his sister upon his benefactor, and gave to Francesco as her dowry the island of Lesbos. On July 17, 1355, Francesco I began his reign[525].
