The chroniclers relate that Ugolino sent the rectors of Florence a present of Vernaccia wine, with gold florins at the bottom of every flask as a bribe.[324] This legend merely signifies that he was considered capable of employing any means to attain his own ends. At all events, he was obliged to impose very cruel sacrifices on Pisa before the Florentines could be induced to suspend hostilities. It was necessary to cede important domains, castles such as Sta Maria a Monte, Fucecchio, Sta Croce, and Monte Calvoli, and to restore the city to the Guelphs by banishing all the Ghibellines--the direst humiliation to a republic that had always been steadfastly Ghibelline. But, with her very existence at stake, Pisa was bound to submit even to this. When, however, the Genoese and Lucchese discovered that the Florentines had deserted them and were siding with Pisa against Lucca, they complained so bitterly of this breach of faith, that Count Ugolino deemed it well to at least silence Lucca by the cession of Bientina, Ripafratta, and Viareggio. In this manner the haughty Pisan Republic was stripped of nearly all its territories outside the city gates, and deprived of all power of defending the coast, at a time when its ships were being chased and plundered by the Genoese on every sea. Amid the general ruin and desolation, however, Ugolino triumphed; for now, being absolute lord of Pisa, his dearest desire was fulfilled. Nevertheless, his power was much less secure than he supposed, for the fiery Pisan spirit was not entirely extinguished, and already the majority of the citizens were growing intolerant of a tyranny at home failing to spare them humiliations abroad. The smallest occasion served to show that public feeling was on the verge of an outbreak. Much discontent was also provoked in the course of negotiations with Genoa for the restitution of the prisoners, comprising many of Pisa's best sons. Their release was desired at any cost; but the count, knowing them to be Ghibellines, and consequently opposed to himself, daily invented fresh obstacles to prevent their return, and by proposing terms the Pisans could not accept, always caused fresh delays. Thus, as he intended, no conclusion could be arrived at. But his arrogance finally produced discord even among his own party. His nephew, Nino Visconti, judge of Gallura, and the natural head of the Guelph faction, began to make overtures to the Ghibellines for the purpose of combating his uncle. Thereupon Ugolino promptly sent many other Ghibellines into exile, and demolished ten of their grandest palaces. This produced an outburst of indignation. Nino made close alliance with the Gualandi and Sismondi, and all tried to hasten the prisoners' release, while the count found fresh pretexts for delay by reviving causes of dispute with Genoa.
