But Caesar was stopped short in the midst of his victories. Thanks to the 200,000 ducats that yet remained in his treasury, Ludovico Sforza had levied 500 men-at-arms from Burgundy and 8000 Swiss infantry, with whom he had entered Lombardy. So Trivulce, to face this enemy, had been compelled to call back Yves d'Alegre and the troops that Louis XII had lent to Caesar; consequently Caesar, leaving behind a body of pontifical soldiery as garrison at Forli and Imola, betook himself with the rest of his force to Rome.
It was Alexander's wish that his entry should be a triumph; so when he learned that the quartermasters of the army were only a few leagues from the town, he sent out runners to invite the royal ambassadors, the cardinals, the prelates, the Roman barons, and municipal dignitaries to make procession with all their suite to meet the Duke of Valentinois; and as it always happens that the pride of those who command is surpassed by the baseness of those who obey, the orders were not only fulfilled to the letter, but beyond it.
The entry of Caesar took place on the 26th of February, 1500. Although this was the great Jubilee year, the festivals of the carnival began none the less for that, and were conducted in a manner even more extravagant and licentious than usual; and the conqueror after the first day prepared a new display of ostentation, which he concealed under the veil of a masquerade. As he was pleased to identify himself with the glory, genius, and fortune of the great man whose name he bore, he resolved on a representation of the triumph of Julius Caesar, to be given on the Piazzi di Navona, the ordinary place for holding the carnival fetes. The next day, therefore, he and his retinue started from that square, and traversed all the streets of Rome, wearing classical costumes and riding in antique cars, on one of which Caesar stood, clad in the robe of an emperor of old, his brow crowned with a golden laurel wreath, surrounded by lictors, soldiers, and ensign-bearers, who carried banners whereon was inscribed the motto, 'Aut Caesar aut nihil'.
Finally, an the fourth Sunday, in Lent, the pope conferred upon Caesar the dignity he had so long coveted, and appointed him general and gonfaloniere of the Holy Church.
In the meanwhile Sforza had crossed the Alps and passed the Lake of Como, amid acclamations of joy from his former subjects, who had quickly lost the enthusiasm that the French army and Louis's promises had inspired. These demonstrations were so noisy at Milan, that Trivulce, judging that there was no safety for a French garrison in remaining there, made his way to Navarra. Experience proved that he was not deceived; for scarcely had the Milanese observed his preparations for departure when a suppressed excitement began to spread through the town, and soon the streets were filled with armed men. This murmuring crowd had to be passed through, sword in hand and lance in rest; and scarcely had the French got outside the gates when the mob rushed out after the army into the country, pursuing them with shouts and hooting as far as the banks of the Tesino. Trivulce left 400 lances at Novarra as well as the 3000 Swiss that Yves d'Alegre had brought from the Romagna, and directed his course with the rest of the army towards Mortara, where he stopped at last to await the help he had demanded from the King of France. Behind him Cardinal Ascanio and Ludovico entered Milan amid the acclamations of the whole town.
Neither of them lost any time, and wishing to profit by this enthusiasm, Ascanio undertook to besiege the castle of Milan while Ludovico should cross the Tesino and attack Novarra.
There besiegers and besieged were sons of the same nation; for Yves d'Alegre had scarcely as many as 300 French with him, and Ludovico 500 Italians. In fact, for the last sixteen years the Swiss had been practically the only infantry in Europe, and all the Powers came, purse in hand, to draw from the mighty reservoir of their mountains. The consequence was that these rude children of William Tell, put up to auction by the nations, and carried away from the humble, hardy life of a mountain people into cities of wealth and pleasure, had lost, not their ancient courage, but that rigidity of principle for which they had been distinguished before their intercourse with other nations. From being models of honour and good faith they had become a kind of marketable ware, always ready for sale to the highest bidder. The French were the first to experience this venality, which later-on proved so fatal to Ludovico Sforza.
Now the Swiss in the garrison at Novarra had been in communication with their compatriots in the vanguard of the ducal army, and when they found that they, who as a fact were unaware that Ludavico's treasure was nearly exhausted, were better fed as well as better paid than themselves, they offered to give up the town and go over to the Milanese, if they could be certain of the same pay. Ludovico, as we may well suppose, closed with this bargain. The whole of Novarra was given up to him except the citadel, which was defended by Frenchmen: thus the enemy's army was recruited by 3000 men. Then Ludovico made the mistake of stopping to besiege the castle instead of marching on to Mortara with the new reinforcement. The result of this was that Louis XII, to whom runners had been sent by Trivulce, understanding his perilous position, hastened the departure of the French gendarmerie who were already collected to cross into Italy, sent off the bailiff of Dijon to levy new Swiss forces, and ordered Cardinal Amboise, his prime minister, to cross the Alps and take up a position at Asti, to hurry on the work of collecting the troops. There the cardinal found a nest-egg of 3000 men. La Trimouille added 1500 lances and 6000 French infantry; finally, the bailiff of Dijon arrived with 10,000 Swiss; so that, counting the troops which Trivulce had at Mortara, Louis XII found himself master on the other side of the Alps of the first army any French king had ever led out to battle. Soon, by good marching, and before Ludovico knew the strength or even the existence of this army, it took up a position between Novarra and Milan, cutting off all communication between the duke and his capital. He was therefore compelled, in spite of his inferior numbers, to prepare for a pitched battle.
But it so happened that just when the preparations for a decisive engagement were being made on both sides, the Swiss Diet, learning that the sons of Helvetia were on the paint of cutting one another's throats, sent orders to all the Swiss serving in either army to break their engagements and return to the fatherland. But during the two months that had passed between the surrender of Novarra and the arrival of the French army before the town, there had been a very great change in the face of things, because Ludovico Sforza's treasure was now exhausted. New confabulations had gone on between the outposts, and this time, thanks to the money sent by Louis XII, it was the Swiss in the service of France who were found to be the better fed and better paid. The worthy Helvetians, since they no longer fought far their own liberty, knew the value of their blood too well to allow a single drop of it to be spilled for less than its weight in gold: the result was that, as they had, betrayed Yves d'Alegre, they resolved to betray Ludovico Sforza too; and while the recruits brought in by the bailiff of Dijon were standing firmly by the French flag, careless of the order of the Diet, Ludovico's auxiliaries declared that in fighting against their Swiss brethren they would be acting in disobedience to the Diet, and would risk capital punishment in the end—a danger that nothing would induce them to incur unless they immediately received the arrears of their pay. The duke, who a spent the last ducat he had with him, and was entirely cut off from his capital, knew that he could not get money till he had fought his way through to it, and therefore invited the Swiss to make one last effort, promising them not only the pay that was in arrears but a double hire. But unluckily the fulfilment of this promise was dependent on the doubtful issue of a battle, and the Swiss replied that they had far too much respect for their country to disobey its decree, and that they loved their brothers far too well to consent to shed their blood without reward; and therefore Sforza would do well not to count upon them, since indeed the very next day they proposed to return to their homes. The duke then saw that all was lost, but he made a last appeal to their honour, adjuring them at least to ensure his personal safety by making it a condition of capitulation. But they replied that even if a condition of such a kind, would not make capitulation impossible, it would certainly deprive them of advantages which they had aright to expect, and on which they counted as indemnification for the arrears of their pay. They pretended, however, at last that they were touched by the prayers of the man whose orders they had obeyed so long, and offered to conceal him dressed in their clothes among their ranks. This proposition was barely plausible; far Sforza was short and, by this time an old man, and he could not possibly
