In the spring of 1507, Julius launched his bull of excommunication against Venice; Ravenna, which was held by the podesta Marcello and by Zeno, was attacked by the pope's general, the duke of Urbino, and after the disastrous defeat of the Venetians by the French and Milanese, at Aguadello, on the Adda, the republic ordered the restoration of Ravenna to the Holy See, together with the other cities of the Romagna.
The pope was now content, but France and the emperor were not, and Venice was forced to ally herself first with one side and then with the other.
In the brutal struggle of the foreigner for Cisalpine Gaul there were two desperate battles, that of Ravenna in 1512, in which the French, though victorious, lost their best leader, Gaston de Foix, and that of Novara in 1513, which induced the French to leave Italy. As the first of these battles concerns Ravenna we must consider it more closely.
At this time Venice was in alliance with Spain and the pope against the French, who were commanded by Gaston de Foix, Duke of Nemours, a nephew of the French king. The combined Spanish and papal troops, about 20,000 strong, were led by Raimondo da Cardona. The French were south of the Apennines when the Papal-Spanish force swung round from Milan into the Ferrarese, seized the territory south of the Po, and laid siege to Bologna. A Venetian force was hurrying to aid them.
Gaston de Foix did not hesitate. On February 5, he flung himself over the ice-bound Apennine and hastened to relieve Bologna. Cardona retreated before him down the Aemilian Way; but Brescia opened its gates to the Venetians, and this, which hindered Gaston, so enraged him that when he had taken the city he gave it up to a pillage in which more than eight thousand were slain and his men "were so laden with spoil that they returned to France forthwith to enjoy it."
Gaston was compelled to return to Milan to re-form his troops, for he was determined both by necessity and by his own nature, which loved decision, to force a battle with the allies. The truth was that the position of France was precarious, her career in Italy was deeply threatened by the allies, Henry VIII. of England contemplated a descent upon Normandy, and until the enemy in Italy was disposed of her way was barred to Naples.
So Gaston set out with some 7000 cavalry and 17,000 infantry, French, Italian, German, to pursue and to defeat Cardona, who did not wish to fight. The army of the allies was chiefly Spanish and it numbered some 6000 cavalry and 16,000 infantry of most excellent fighting quality.
As the French advanced along the Via Aemilia, Cardona withdrew to Faenza. Gaston went on to Ravenna, which he besieged. Cardona was forced to intervene and try to save the city. He, too, approached Ravenna. Upon Easter Day, 1512, the two armies met in the marsh between Ravenna and the sea; and, in the words of Guicciardini, "there then began a very great battle, without doubt one of the greatest that Italy had seen for these many years…. All the troops were intermingled in a battle fought thus on a plain without impediments such as water or banks, and where both armies fought, each obstinately bent on death or victory, and inflamed not only with danger, glory, and hope, but also with the hatred of nation against nation. It was a memorable spectacle in the hot engagement between the German and Spanish infantry to see two very noted officers, Jacopo Empser, a German, and Zamudio, a Spaniard, advance before their battalions and encounter one another as if it were by challenge, in which combat the Spaniard went off conqueror by killing his adversary. The cavalry of the army of the League was not at best equal to that of the French, and having been shattered and torn by the artillery was become much inferior. Wherefore after they had sustained for some time, more by stoutness of heart than by strength of arms, the fury of the enemy, Yves d'Allegre with the rearguard and a thousand foot that were left at the Montone under Paliose and now recalled charging them in flank, and Fabrizio Colonna, fighting valiantly, being taken prisoner by the soldiers of the Duke of Ferrara, they turned their backs, in which they did no more than follow the example of their generals; for the Viceroy and Carvagiale, without making the utmost proof of the valour of their troops, betook themselves to flight, carrying off with them the third division or rearguard almost entire with Antonio da Leva, a man of that time of low rank though afterwards by a continual exercise of arms for many years, rising through all the military degrees, he became a very famous general. The whole body of light horse had been already broken, and the Marchese di Pescara, their commander, taken prisoner, covered with blood and wounds. And the Marchese della Palude, who had led up the second division, or main battle, through a field full of ditches and brambles in great disorder to the fight, was also taken. The ground was covered with dead men and horses, and yet the Spanish infantry, though abandoned by the horse, continued fighting with incredible fierceness; and though, at the first encounter with the German foot, they had received some damage from the firm and close order of the pikes, yet afterwards getting their enemies within the length of their swords, and many of them, covered with targets, pushing with daggers between the legs of the Germans, they had penetrated with very great slaughter almost to the centre of their battalions. The Gascon foot who were posted by the Germans on the ground between the river and a rising bank had attacked the Italian infantry, which, though they had greatly suffered by the artillery, would have repulsed them highly to their honour, had not Yves d'Allegre entered among them with a squadron of horse. But the fortune of that general did not answer his valour, for his son Viverais being almost immediately killed before his eyes, the father, unwilling to survive so great a loss, threw himself with his horse into the thickest of the enemies, where, fighting like a most valiant captain and killing several, he was at last cut to pieces. The Italian foot, unable to resist so great a multitude, gave way; but part of the Spanish infantry hastening to support them, they rallied. On the other side, the German infantry, being sorely pressed by the other part of the Spaniards, were hardly capable of making any resistance; but the cavalry of the confederates being all fled out of the field, Foix with a great body of horse turned to fall upon them. The Spaniards, therefore, rather retiring than driven out of the field, without the least disorder in their ranks, took their way between the river and the bank, marching slowly and with a close front, by the strength of which they beat off the French and began to disengage themselves; at which time Navarre, choosing rather to die than to save himself, and therefore refusing to leave the field, was made a prisoner. But Foix, thinking it intolerable that this Spanish infantry should march off in battle array like conquerors and knowing that the victory was not perfect if these were not broken and dispersed like the rest, went furiously to attack them with a squadron of horse and did execution upon the hindmost; but being surrounded and thrown from his horse, or, as some say, his horse falling upon him, while he was fighting, he received a mortal thrust with a pike in his side. And if it be desirable, as it is believed, for a man to die in the height of his prosperity, it is certain that he met with a most happy death in dying after he had obtained so great a victory. He died very young, but famous through the world, having in less than three months, and being a general almost before he was a soldier, with incredible ardour and expedition obtained so many victories. Near him lay on the ground for dead Lautrec, having received twenty wounds; but being carried to Ferrara he was by diligent care of the surgeons recovered.
"By the death of Foix, the Spanish infantry were suffered to pass off unmolested, the remainder of the army being already dispersed and put to flight, and the baggage, colours, and cannons taken. The pope's legate was also taken by the Stradiotti and carried to Federigo da Bozzolo, who made a present of him to the legate of the council. There were taken also Fabrizio Colonna, Pietro Navarra, the Marchese della Palude, the Marchese di Bitonto, and the Marchese di Pescara, with many other lords, barons, and honourable gentlemen, Spaniards and Neapolitans. Nothing is more uncertain than the number of the killed in battles; but amidst the variety of accounts it is the most common opinion that there died of both armies at least 10,000, of which a third was of the French and two-thirds of their enemies: some talk of many more, but they were without question almost all of them of the most valiant and choice soldiers, among whom, belonging to the papal forces, was Raffaello de' Pazzi, an officer of high reputation; and great numbers were wounded. But in this respect the loss of the conqueror was without comparison much the greater by the death of Foix, Yves d'Allegre, and many of the French nobility, and many other brave officers of the German infantry, by whose valour, though at vast expense of their blood, the victory was in a great measure acquired. Molard also fell with many other officers of the Gascons and Picards, which nation lost all their glory that day among the French. But their loss was exceeded by the death of Foix, with whom perished the very sinews and spirits of that army. Of the vanquished that escaped out of the field of battle the greater part fled towards Cesena, whence they continued their flight to more distant places; nor did the Viceroy stop till he came to Ancona where he arrived with a very few horse. Many were stripped and murdered in their flight; for the peasants scoured all the roads and the Duke of Urbino, who from his sending some time before Baldassare da Castiglione to the King of France, and employing some trusty persons as his agents with Foix, was supposed to have entered into a private agreement against his uncle, not only raised the country against those that fled, but sent his soldiers to intercept them in the territories of Pesaro; so that only those who took their flight through the dominions of the Florentines were by orders of the magistrates, confirmed by the republic, suffered to pass unmolested.
"The victorious army was no sooner returned to camp than the people of Ravenna sent deputies to treat of surrendering their city; but when they had agreed or were upon the point of agreement, and the inhabitants being employed in preparing provisions to be sent to the camp were negligent in guarding the walls, the German and Gascon foot entered through the breach that had been made and plundered the town in a most barbarous manner, their cruelty being exasperated not only by their natural hatred to the name of the Italians, but by a spirit of revenge for the loss they had sustained in the battle. On the fourth day after this, Marcantonio Colonna gave up the citadel, into which he had retired, on condition of safety to their persons and effects, but obliging himself on the other hand, together with the rest of the officers, not to bear arms against the King of France nor the Pisan Council till the next festival of S. Mary Magdalen; and not many days after, Bishop Vitello, who commanded in the castle with a hundred and fifty men, agreed to surrender it on terms of safety for life and goods. The cities of Imola, Forli, Cesena, and Rimini, and all the castles of the Romagna, except those of Forli and Imola, followed the fortune of the victory and were received by the legate in the name of the council."
