Their countrymen threatened to support their cause; but the long and open village of Galata was instantly surrounded by the Imperial troops; till, in the moment of the assault, the prostrate Genoese implored the clemency of their sovereign.

The defenceless situation which secured their obedience exposed them to the attack of their Venetian rivals, who, in the reign of the elder Andronicus, presumed to violate the majesty of the throne.

On the approach of their fleets, the Genoese, with their families and effects, retired into the city: their empty habitations were reduced to ashes; and the feeble prince, who had viewed the destruction of his suburb, expressed his resentment, not by arms, but by ambassadors.

This misfortune, however, was advantageous to the Genoese, who obtained, and imperceptibly abused, the dangerous license of surrounding Galata with a strong wall; of introducing into the ditch the waters of the sea; of erecting lofty turrets; and of mounting a train of military engines on the rampart.

The narrow bounds in which they had been circumscribed were insufficient for the growing colony; each day they acquired some addition of landed property; and the adjacent hills were covered with their villas and castles, which they joined and protected by new fortifications.
