It might seem that Uguccione, whether ill or not on the day of battle, was jealous, and perhaps afraid, of Castruccio. Certainly he plotted against him, sending his son Nerli to Lucca with orders to trap Castruccio and imprison him; which was done. Nerli, however, wanted resolution to kill him; and his father hearing this, set out from Pisa with four hundred horse to take the matter in hand. The Pisans, who were by this time completely enslaved by Uguccione, seized the opportunity to rise. Macchiavelli tells us "they cut his Deputies' throats, and slew all his Family. Now, that he might be sure they were in earnest, they chose the Conte de Gherardesca, and made him their Governor." When Uguccione got to Lucca he found the city in an uproar, and the people demanding the release of Castruccio. This he was compelled to allow. With Castruccio at liberty, Lucca was too hot for him, and he fled into Lombardy to the Lords of Scala, where no long time after, he died. After the great victory of Montecatini, Gherardesca and Castruccio soon came to terms with the Guelphs; and all that Pisa really seems to have gained by the war was that she was compelled to build a hospital and chapel for the repose of the souls of the dead at Montecatini. This chapel, hidden away in the Casa dei Trovatelli at the top of Via S. Maria in Pisa, became a glorious monument of the victory of Pisa over Florence. But the freedom of Pisa was gone for ever; others, lords and tyrants, arose, Castruccio Castracani and the rest, yet she was still at bay. On the 2nd October 1325 she again defeated Florence at Altopascio, and even excluded her from the port, and, in 1341, when Florence had bought Lucca from Mastino della Scala for 250,000 florins, she besieged it to prevent the entry of the Florentine army then aided by Milan, Mantova, and Padova, In 1342, the Florentines having failed to relieve Lucca, the Pisans entered the city. The possession of Lucca seemed to put Pisa, where centuries ago Luitprand had placed her, at the head of the province of Tuscany. This view, which certainly she herself was not slow to take, was confirmed when Volterra and Pistoja placed themselves under her protection; yet, as ever, her greatest danger was the discord within her walls. The Republic was weak, nearly a million and a half of florins had been spent on the war, and many tyrants were her allies; moreover, she had lent troops to Milan.[37] It was this moment of reaction after so great an effort that Visconti d'Oleggio chose for a conspiracy against Gherardesca the Captain-General. It is true the plot was discovered, the traitors exiled, and Visconti banished; but the mischief was done. When Lucchino Visconti heard of it in Milan, he imprisoned the Pisan troops in that city and sent Visconti d'Oleggio back with two thousand men to seize Pisa. Thus the war dragged on; and though these Milanese were destroyed for the most part by malaria in the Maremma, still Pisa had no rest.
