CASTRUCCIO’S NEW CONQUEST; HIS SUDDEN DEATH
While Castruccio was steadying himself in the government of Pisa, Sanguineto and the Florentines were in high disputation about putting their recent conquests into a proper state of defence; the former insisting that he had done his part in capturing the town, while the citizens maintained that the duke was bound to discharge such expenses from his salary. The altercation continued and Pistoia remained unvictualled; but the Florentines, having gained some trifling advantages, grew as careless and confident as if fortune had never left their arms, while Castruccio hurried on his preparations for recapturing the neglected place. Nevertheless the Pisans and even his former adherents, now disliking his arbitrary sway, offered their city to Ludwig; he, fearful of alienating Castruccio, referred them to the empress, by whom it was accepted and her vicar immediately despatched to take the reins of government. Castruccio was not thus to be despoiled; he received the officer respectfully, but scoured the city with his horsemen in the manner of the age as a mark of sovereignty; then dismissed the imperial lieutenant loaded with gifts and caused himself to be elected and proclaimed absolute lord of Pisa for two years.
Thus master of new and abundant resources, he lost no time in profiting by the disputes at Florence, and immediately invested Pistoia with a thousand men-at-arms and numerous infantry; the place was strong, encompassed by a double ditch, and defended by Simone della Tosa with a sufficient garrison besides many Guelfic citizens. There was a protecting force at Prato only ten miles off and within sight of its signals, so that if the town had been well provisioned it might have withstood all Castruccio’s efforts until sickness compelled him to retreat. This chief, who had remained at Pisa to complete his preparations, joined the army on the 30th of May bringing strong reinforcements, and surrounded the town with a palisaded ditch and lines of circumvallation. Here he resolved to remain; nor did all the Florentine stratagems succeed in turning him from his purpose, not even when they collected a formidable army of twenty-six hundred men-at-arms and for three days successively defied him to battle, which he constantly pretended to accept, while he only strengthened his camp with additional trenches, fresh palisades, and wide-branching abbati.
Seeing no chance of provoking him, the allies changed their position, and attacked the strongest point of his entrenchments with as little skill as success, instead of cutting off his supplies by Serravalle, which he would have been unable to prevent without a battle.
Sanguineto fell sick and had moreover quarrelled with some of the confederate chiefs, so that he deemed it best to retire and make a diversion elsewhere, leaving a strong convoy at Prato ready to succour the place when a fair occasion offered. On the 28th of July, after delivering another formal challenge which Castruccio was too sagacious to accept, the confederated army drew off towards Prato and thence marched in two divisions, one by Signa and the Gusciana to threaten Lucca, the other by the left bank of the Arno, which destroyed Pontadera and carried the rampart and Fosso Arnonico by storm. This was a great canal and breastwork excavated and fortified with towers by the Pisans in 1176, both as a national bulwark and an outlet for the superfluous waters of the Arno, of which river some have supposed it to be one of the three branches mentioned by Strabo. Thus was opened all the Pisan territory; San Casciano and Sansavino soon fell and Pisa saw herself insulted at her very gates with perfect impunity. Castruccio nevertheless remained immovable; he calculated on starvation and the moral effect of seeing a superior army retire without accomplishing anything, and accordingly on the 3rd of August Pistoia surrendered to sixteen hundred men-at-arms and the usual force of infantry, in face of an army of nearly double these numbers.
Thus victorious he returned in triumph to Lucca, more powerful, more dreaded, and more formidable than before; none of his important enterprises ever failed and Italy had not beheld such a captain for centuries. Lord of Pisa, Lucca, Lunigiana, and much of the eastern Riviera of Genoa, and master of three hundred walled towns, he was either courted or dreaded by every Italian prince from the emperor downwards. But Florence was in terror at his very name; and Galeazzo Visconti the once powerful lord of half Lombardy, who had been released by the emperor in the preceding March at Castruccio’s intercession, now served under his standard as a private individual. Visconti soon after expired at Pescia from the effects of a fever engendered by the labours of the Pistoian siege, and it was fatal to more than him: even Castruccio’s hour drew near; for the same fever, the consequence of his personal fatigues, was rapidly consuming him also. He feared the emperor’s resentment for the usurpation of Pisa and would have made peace with Florence, but was too much mistrusted and therefore failed. The malady increased; he informed those about him that he was going to die and that his death would be the signal for great revolutions; then, taking the necessary precautions to insure his three sons the quiet succession of his three great cities, and charging them to conceal his death until they were secure, he expired on the 3rd of September, 1328, in the forty-seventh year of his age and the twelfth of his rule over Lucca.
