The siege lasted for seven months. No noble deeds of valour and chivalry distinguished the German Paladin’s emprise; he accomplished his work by the slow and cruel hand of famine. Every gate was closely blockaded, and all compassionate bearers of food from outside to the starving people were almost without exception captured, and either ruthlessly scourged or maimed of the right hand. Frederick showed the besieged none of the respect due to gallant foes. He strung up his prisoners on gallows, nobles and plebeians alike, in the view of their kinsfolk and friends within, or sent them back sightless into the city. Within the walls, hunger reached such a pitch that in their madness husbands and wives, fathers and sons, turned upon one another. The hideous selfishness of bodily need disfigured the gaunt faces in the streets, while the spectacle of the mutilated wretches who had passed through the Emperor’s hands, breathed into all hearts dreadful apprehensions of their future fate. In their despair the people cried out for surrender, and at last the Consuls, aware of the inflexibility of the foe, and fearing that to resist longer was to sacrifice the entire people to the extremity of his vengeance, threw themselves upon the mercy of the Emperor, and surrendered the city at discretion (1162).
The scenes which follow paint vividly for us the tragedy of the great city’s downfall. The magnitude of the punishment which Frederick meted out to Milan invests him with a kind of sublimity. This was his opportunity to deliver a blow which should resound to the four corners of the earth, and accomplish, once for all, by the horror of its mere narration, the subjugation of the rest of rebellious Lombardy. None knew better than this mediæval monarch how to surround his revenge with all those awful aspects and illusions of terror that impress the minds of men. Day after day, processions of citizens, with bowed heads, and ropes round their necks, presented themselves before him at his command, as he sat enthroned in state in rebuilt Lodi, the Empress Beatrice at his side, his vassal kings and princes on either hand, and still the doom of the city remained unspoken. The eight Consuls—some of the noblest patricians of Milan—came, holding their naked swords in their right hands, and swore to do the will of the Conqueror. Next appeared three hundred cavaliers, and kissing the Emperor’s foot, delivered up to him the Milanese standards; while to Mastro Guitelmo, a man much revered by his fellow-citizens, was committed the bitter charge of laying the keys at his feet. Still another mark of humiliation was demanded of them, and a day or two later came the Sacred Car itself, with the banner of the Cross, and all the most venerable insignia of the Republic, to be surrendered for the completion of Milan’s shame.
Then at last the voice from the throne spoke, commanding that beside every gate of the city the fosse should be filled up and the walls destroyed, so that he might march in in triumph. Milan—who for centuries had proudly claimed the right of keeping all sovereigns excluded from the enclosure of her walls—was now herself to lay low her defences to admit a victorious monarch. A few days later Frederick made his entrance with his army over the ruined walls, and the dreadful fiat went forth, dooming the great city to complete destruction. The inhabitants were ordered to quit their homes, taking with them what they could carry. No entreaty, no tears, even of his own followers, could move Frederick’s resolve. The piteous spectacle of the outcast people, huddled in masses outside the walls in the bitter cold of March, homeless, not knowing where to go, and uttering loud lamentations, could not change his inexorable purpose. With an extremity of cruelty he committed the work of ruin to Milan’s neighbours and bitterest foes—the men of Lodi, Pavia, Novara, Como, Cremona—all burning to retaliate a thousand wrongs. They threw themselves with fury upon the doomed buildings, each community satiating its vengeance on the quarter facing towards its own city. In a very few days an incredible amount of destruction was wrought. But it was the work of months to raze to the ground the towers, the fine palaces and public buildings, many of them surviving from the days of the Roman Empire, and the crowded habitations of a vast population. The churches and religious houses alone were spared, and for a while the campanile of the Cathedral, a tower of admirable beauty and height, which had not its like, they say, in all Italy, still rose untouched above the ruins, a beacon of consolation to the despairing people. But at last, the implacable decree of the conqueror pronounced its sentence, and that, too, fell. Finally not more than a fifth part of the fair city, which men called the flower of Italy—the May City—was left standing.
From the spectacle of burning Milan, which he watched with his own eyes, the magnanimous Avenger passed on with his Empress to celebrate the Feast of Olives at Pavia! Frederick was now the dread of all Italy. The trembling cities of Lombardy crept to his feet and kissed them. The crown of Italy, hitherto withheld from him and now conceded by fear, was set upon his head. As for the Milanese, crowded in the poor villages and suburbs around their ruined city, and barely able to exist, they were fain to accept any conditions which he imposed.
But the great Emperor’s fortunes had reached the flood, and the turn was at hand. To have made his triumph enduring he must have exterminated all Lombardy. While the Milanese people breathed, the Republic lived in spirit, only awaiting the least relief from the pressure of the conqueror to take substance once again. And now that its sins and arrogance had been wiped out by such an awful expiation, the hatred and jealousy of the sister Communes changed to compassion. The deep roots of a common nationality began to stir. Moreover, all were enslaved alike, all groaned together under the intolerable oppression of the imperial officers who had been substituted for their old system of self-government. ‘They who had been used to live without restraint at ease and in liberty, and to dispose of their own affairs according to their will, held this bondage as the deepest shame, saying among themselves that it was better to die than to suffer such shame, such dishonour,’ writes Morena. Ground down with grievous and irregular taxation, their noblest citizens flung as hostages into the governors’ dungeons, their industry and commerce strangled, they began to regard war even with the terrible Barbarossa as preferable to this degradation and slow ruin. Their spirit of revolt was encouraged by that great counterbalancing power to the Empire, the Papacy, which after a period of schism and depression was lifting its head once more. In Alexander III., now completely victorious over the rival Pope Victor, nominated by Barbarossa, the Communes found that inspiration and direction which it was Rome’s traditional part to give to the cause of freedom and nationality. The papal excommunication laid upon their oppressor gave the consecration of a religious cause to rebellion. Fomented by secret emissaries from Rome, the movement grew and gathered head. Disturbances broke out everywhere in North Italy, and culminated in a meeting of envoys from five Communes—Brescia, Bergamo, Cremona, Mantua, Ferrara—with the delegates of Milan at a convent near Bergamo (1167), and the formation of a defensive alliance, which was to become the famous Lombard League. The first thing resolved on by the allies was the rebuilding of Milan and the protection of the city from every foe until she should grow strong enough to defend herself. A week or two later the unhappy Milanese, huddling together in their wretched hovels, and momentarily expecting a second destruction from their old enemies of Pavia, were rejoiced at the sight of the horsemen of Bergamo, with their banner displayed, riding swiftly to their succour. Troops from the other friendly cities followed. The Milanese were solemnly conducted into their ruined city on the 27th April 1167, and the work of restoration began. With marvellous rapidity new walls and dwellings grew up. Gathering confidence and strength every day, the League soon broke into active hostility against those communities which remained faithful to the Emperor, and the castles occupied by his garrisons. Lodi was compelled by force to join the new fellowship. Fresh accessions came continually, and by the end of the following year the League numbered twenty-three cities, all sworn to resist the usurpations of the emperor with the sword. Pavia, almost alone, remained aloof, faithful to her hate of Milan.
Frederick, returning hastily from a campaign against the Pope, found his castles captured, Milan re-risen defiant from her ashes, and all North Italy armed against him. The Emperor was not equal to this new situation. His former triumph had, in fact, only been achieved by the aid of a part of the cities themselves, and his German levies, diminished by fighting and pestilence, were powerless to contend with a vast hostile combination of all together. His army and his very person were in utmost peril. There was one way only of salvation for him—retreat. In a manner very different to the majesty of his coming, with furtive haste, unknown even to his allies, he stole back to Germany early in 1168.
Six years passed before the Emperor felt himself strong enough to confront his rebellious vassals again. In his prolonged absence the Lombard League had acquired mighty strength. Milan had arisen from her chastening of shame and sorrow stronger and more honourable than before. Renouncing her old vexatious claims upon her smaller neighbours, she now contented herself with the dignity of leadership among the Communes. The League gathered itself together to meet the new onslaught of Barbarossa, and though he spread terror and desolation throughout the land, his effort to subdue the steady resistance of the cities was fruitless. His purpose was contrary to the laws of nature, and the stars in their courses fought against him. Pavia, Como and the Marquis of Montferrat supported him alone of all North Italy. In May 1176, impatient to strike a crushing blow against the rebels, Frederick was marching with new reinforcements from Germany to join his Lombard allies when, a few miles from Milan, between Busto Arsizio and Legnano, he encountered the Milanese army, which had come forth with the Sacred Car in its midst to stay his progress. A great battle took place. Driven back at first by the Teuton cavalry, the Republican soldiers, who had taken a desperate vow to conquer or to die, rallied around the Caroccio, and fought with such obstinate courage that they beat back every assault of the foe, and at last, with a sudden rush, utterly routed them and drove them into flight. The slain, the captives, and the fugitives drowned in the Ticino could not be numbered. The monarch’s treasure-chest fell into the hands of the victors, and a more precious booty still, his shield, his banner and his lance. His very person was missing after the battle, and the Empress, waiting in the Castle of Baradello, clothed herself in black and mourned him for dead. He had, however, escaped in safety, and a few days later made his way to Pavia.
The splendid victory of Legnano decided once and for all the fate of Lombardy. Frederick realised at last the strength of the despised citizen forces, and condescended to seek for peace. In the following year (1177) at Venice was held that famous meeting of Pope, Emperor and the Consuls of the Lombard Communes, at which legend and art express the humiliation of the invader and the triumph of Italy, by picturing the monarch prostrate beneath the foot of the Pope. A truce of six years was agreed upon at this Congress, and at the end of that period the famous Peace of Constance (1183) finally confirmed to the cities all the privileges for which they had so nobly fought. The right of self-government, of war and peace, the possession of the regalia, with other minor prerogatives, were secured to them in perpetuity, and the only dues to be paid by them to the Emperor were a ceremonial fealty, an annual tribute, certain supplies when he visited the country in person, and the acceptance of his legate as the ultimate judge in the courts of judicature.
Thus did Lombardy win freedom. For reborn Milan, her new position and dignity was signalised in 1186 by the appearance of her late foe and oppressor in the character of a gracious guest, and the celebration of the marriage of his son, Henry, King of the Romans, with Constance of Sicily, in the basilica of St. Ambrogio. But the narrow crooked streets that had grown hastily up around the churches, and the few surviving fragments from the destruction of 1162, were no image of the imperial Milan of the past, nor did the fair words and mutual promises of friendship which passed between Frederick and the citizens express the real feelings of either party. When, sick at the failure of his worldly projects, the yet vigorous warrior turned his ambition to that holier enterprise, the conquest of the Sepulchre of Christ, and leaping one hot day into an insignificant stream in Syria, was drowned in its shallow flow, all Milan broke into rejoicing. Nor was there ever kindness between the Republic and his descendants. The Milanese consistently opposed and thwarted the policy of Henry VI., and after his early death did their utmost to depress the House of Suabia by warmly supporting Otho IV. against the interests of Henry’s infant son Frederick.
During the reign of Otho, while the political field was divided between him and the young Suabian prince, the disputed imperial authority had no power to harm, and Milan was free to resume the interrupted process of development and expansion. As before, this process was not a peaceful one. The subsidence of the Teutonic flood had left behind bitter dregs in Lombardy in the shape of new causes of feud and animosity between individual Communes. Relieved from the pressure of Frederick’s tyranny, the cities readjusted themselves on the lines of their former divisions. The Lombard League broke up into warring elements, and the restless land fermented with a cruel internecine strife.
