Often after that, Dianora and Antonio too, seeing him ride by in attendance on Francesco, would admire with what address he sat his horse, with what grace he managed his lance, with what comeliness his sword; and indeed scarce any of his age dare meet him at the Barriere. He was about eighteen years old when he made his first campaign. For the Guelphs had driven the Ghibellines out of Pavia, and Visconti sought the help of his friends, among them of Francesco Guinigi. Francesco gave Castruccio a company of foot, and marched with him to help Visconti: and Castruccio won such reputation in that fight, that his name galloped through Lombardy, and when he returned to Lucca the whole city had him in respect.

Not long after, Guinigi fell sick; in truth he was about to die. Seeing, then, that he had a son scarcely thirteen years old, called Pagolo, he gave him into Castruccio's charge, begging him to show the same generosity to his son as he had received from him. And all this Castruccio promised.

Now the head of the Guelph party in Lucca was a certain Signor Giorgio Opizi, who hoped when Francesco was dead to get the city into his power, so that when he saw Castruccio so well thought of and so strong, he began to speak secretly of a new tyranny, by which he meant the growing favour of Castruccio. Pisa at this time was under the government of Uguccione della Faggiuola of Arezzo, whom the Pisans had chosen as their captain, but who had made himself their lord. He had befriended certain Ghibellines banished from Lucca, and therefore Castruccio entered into secret treaty with him in order that these exiles might be restored. So he furnished in Lucca the Tower of Honour, which was in his charge, in case he might have to defend it. He met Uguccione on the night appointed, between Lucca and the hills towards Pisa, and, agreeing with him, Uguccione marched on the city to St. Peter's Gate and set fire to it, while he attacked another on the other side of the town. Meanwhile, his friends within the city ran about in the night calling To your arms, and filled the streets with confusion; so that Uguccione easily entered, and, having seized the city, caused all the Opizi to be murdered as well as all the Guelphs he could find. Nor did he stop there, for he exiled one hundred of the best families, who immediately fled to Florence and Pistoja. The Florentines, seeing the Guelph power tottering, put an army in the field, and met the Pisans and Lucchesi at Montecatini. There followed the memorable battle called after that place, in which the Florentines lost some ten thousand men. [ [144] ] This was in 1315. Now whether, as Villani says, Uguccione won that battle, or, as Machiavelli asserts, was sick, so that the honour fell to Castruccio, there was already of necessity much jealousy between the two captains; for certainly Castruccio had not called on Uguccione to make him Lord of Lucca, nor had Uguccione obeyed that call for mere love of Castruccio. He therefore, being returned to Pisa, sent his son Nerli to seize Lucca and kill Castruccio, but the lad bungled it: when Uguccione himself set out to repair this, he found the city ready, demanding the release of Castruccio, whom Nerli had imprisoned. Seeing, then, the mood of the city, and that he had but four hundred horse with him, he was compelled to agree to this. And at once Castruccio, who was in no wise daunted, assembled his friends and flung Uguccione out of Lucca. Meantime the Pisans had themselves revolted, so that this tyrant was compelled to retire into Lombardy.

It was now that Castruccio saw his opportunity. He got himself chosen Captain-General of all the Lucchese forces for a twelvemonth, and began to reduce the surrounding places near and far which had come under the rule of Uguccione. The first of these to be attacked was Sarzana in Lunigiana. But first he agreed with Pisa, who in hatred of Uguccione sent him men and stores. Sarzana proved very strong, so that before he won it he was compelled to build a fortress beyond the walls, which we may see to this day. Thus Sarzana was taken, and later Massa, Carrara, and Avenza easily enough, until the whole of Lunigiana was in his power, even Fosdinovo, and later Remoli, and that was to secure his way to Lombardy. Then he returned to Lucca, and was received with every sort of joy.

About this time Ludovic of Bavaria came into Italy seeking the Imperial Crown, and Castruccio went to meet him with 500 horse, leaving Pagolo Guinigi his Deputy in Lucca. Ludovic received him with much kindness, making him Lord of Pisa and his vicar in all Tuscany: and thus Castruccio became the head of the Ghibelline party both in Lombardy and Tuscany. But Castruccio's aim went higher yet, for he hoped not only to be vicar but master indeed of Tuscany, and to this end he made a league with Matteo Visconti of Milan; and seeing that Lucca had five gates, he divided the country into five parts, and to every part he set a captain, so that presently he could march with 20,000 men beside the Pisans. Now the Florentines were already busy in Lombardy against Visconti, who besought Castruccio to make a diversion. This he readily did, taking Fucecchio and S. Miniato al Tedesco. Then hearing of trouble in Lucca, he returned and imprisoned the Poggi, who had risen against him; an old and notable family, but he spared them not. Meanwhile Florence retook S. Miniato; and Castruccio, not caring to fight while he was insecure at home, made a truce carefully enough, that lasted two years.

He now set himself first to make Lucca secure, and for this he built a fortress in the city; and then to possess himself of Pistoja—for he even thought thereby to gain a foothold in Florence herself—and for this he entered into correspondence secretly with both the Neri and the Bianchi there. These two factions did not hesitate to use the enemy of their city to help their ambitions, so that while the Bianchi expected him at one gate, the Neri waited at the other, the one receiving Guinigi and the other Castruccio himself with their men into the city. Not content with thus winning Pistoja, he thought to control the city of Rome also, which he did in the name of the Emperor, the Pope being in Avignon; and this done, he went through the city with two devices embroidered on his coat: the one before read, "He is as pleaseth God," and that behind, "And shall be what God will have him." Now the Florentines were furious at the cunning breach of their truce by which Castruccio had got himself Pistoja; so, while he was in Rome, they determined to capture the place: which they did one night by a ruse, destroying all Castruccio's party. And when he heard it, Castruccio came north in great anger. But at first the Florentines were too quick for him: they got together all of the Guelph league, and before Castruccio was back again, held Val di Nievole. Seeing their greatness—for they were 40,000 in number, while he on his return could muster but 12,000 men at most—he would not meet them in the plain, nor in the Val di Pescia, but resolved to draw that great army into the narrow ways of Serravalle, where he could deal with them. Now Serravalle is a Rocca not on the road but on the hillside above, and the way down into the valley is rather strait than steep till you come to the place where the waters divide: so strait that twenty men abreast take up all the way. That Rocca belonged to a German lord called Manfredi, whose throat Castruccio cheerfully cut. The Florentines, who were eager not only to hold all Val di Nievole but to carry the war away from Pistoja towards Lucca, knew nothing of Serravalle having fallen to Castruccio, so on they came in haste, and encamped above it, hoping to pass the straits next day. There Castruccio fell upon them about midnight, putting all to confusion. Horse and foot fell foul upon one another, and both upon the baggage. There was no way left for them but to run, which they did helter-skelter in the plain of Pistoja, where each man shifted for himself. But Castruccio followed them even to Peretola at the gates of Florence, carrying Pistoja and Prato on the way; there he coined money under their walls, [ [145] ] while his soldiers insulted over the conquered; and to make his triumph more remarkable, nothing would serve the turn but naked women must run Corsi on horseback under the very walls of the city. And to deliver their city from Castruccio, the Florentines were compelled to send to the King of Naples, and to pay him annual tribute.

But Castruccio's business was always spoiled by revolt, and this time it was Pistoja which rose, and later Pisa. Then the Guelphs raised a great army—30,000 foot and 10,000 horse it was—and after a little, while Castruccio was busy with Pisa, they seized Lastra, Signa, Montelupo, Empoli, and laid siege to S. Miniato: this in May 1328. Castruccio, in no wise discomposed, thought at last Tuscany was in his grasp; therefore he went to Fucecchio and entrenched himself with 20,000 foot and 4000 horse, leaving 5000 foot in Pisa with Guinigi. Fucecchio is a walled city on the other side of Arno opposite S. Miniato. There Castruccio waited; nor could he have chosen better, for the Florentines could not attack him without fording the river from S. Miniato, which they had taken, and dividing their forces. This they were compelled to do, and Castruccio fell upon and beat them, leaving some 20,000 of them dead in the field, while he lost but fifteen hundred. Nevertheless, that proved to be his last fight, for death found him at the top of his fortune; riding into Fucecchio after the battle, he waited a-horseback to greet his men at the great gate of the place which is still called after him. Heated as he was with the fight, it was the evening wind that slew him; for he fell into an ague, and, neglecting it, believing himself sufficiently hardened, it presently killed him, and Pagolo Guinigi ruled in his stead, but without his fortune.

Following that strangely successful career, that for Macchiavelli at any rate seemed like a promise of the Deliverer that was to come, the first of modern historians gives us many of Castruccio's sayings set down at haphazard, which bring the man vividly before us. Thus when a friend of his, seeing him engaged in an amour with a very pretty lass, blamed him that he suffered himself to be so taken by a woman—"You are deceived, signore," says Castruccio, "she is taken by me." Another desiring a favour of him with a thousand impertinent and superfluous words—"Hark you, friend," says Castruccio, "when you would have anything of me, for the future send another man to ask it." Something of his dream of dominion may be found in that saying of his when one asked him, seeing his ambition, how Caesar died, and he answered, "Would I might die like him!" Blamed for his severity, perhaps over the Poggi affair, one said to him that he dealt severely with an old friend—"No," says he, "you are mistaken; it was with a new foe." Something of his love for Uguccione—who certainly hated him, but whom he held in great veneration—may be found in his answer to that man who asked him if for the salvation of his soul he never thought to turn monk. "No," says he, "for to me it will be strange if Fra Nazarene should go to Paradise and Ugguccione della Faggiuola to Hell." And Macchiavelli says that what was most remarkable was that, "having equalled the great actions of Scipio and Philip, the father of Alexander, he died as they did, in the forty-fourth year of his age, and doubtless he would have surpassed them both had he found as favourable dispositions at Lucca as one of them did in Macedon and the other in Rome." Just there we seem to find the desire of the sixteenth century for unity that found expression in the deeds of Cesare Borgia, the Discorsi of Niccolò Macchiavelli.
