His engines of war, however, were insufficient to beat down the walls of so strong and large a town; and he resolved to reduce the Milanese by famine. He seized their granaries, burned their stacks of corn, mowed down the autumnal harvests, and announced his resolution not to raise the siege till the Milanese had returned to their duty. The few nobles, however, who had preserved their independence in Lombardy, proceeded to the camp of the emperor. One of them, the count of Blandrate, who had before given proofs of his attachment to the town of Milan, offered himself as a mediator, was accepted, and obtained terms not unfavourable to the Milanese. They engaged to pay a tribute to Frederick of nine thousand marks of silver, to restore to him his regal rights, and to the towns of Lodi and Como their independence. On their side, they were dispensed from opening their gates to the emperor. They preserved the right of electing their consuls, and included in their pacification their allies of Tortona and Crema. This treaty was signed the 7th of September, 1158.
An Italian Nobleman, Thirteenth Century
Frederick, in granting an honourable capitulation to revolted subjects, whom he had brought back to their obedience, had no intention of renouncing the rights of his empire. He considered that he had preserved, untouched, the legislative authority of the diet of his kingdom of Italy. The Milanese, on the contrary, regarded their treaty as definitive; and were both astonished and indignant when Frederick, having assembled, towards the 11th of November following, the placita or diets of the kingdom at Roncaglia, promulgated by this diet a constitution which overthrew their most precious rights. It took the administration of justice from the hands of the consuls of towns, to place it in those of a single judge, and a foreigner, chosen by the emperor, bearing the name of podesta; it fixed the limits of the regal rights, giving them much more importance than had been contemplated by the Milanese when they agreed to acknowledge them; it deprived cities, as well as the other members of the empire, of the right of making private war; it changed the boundaries of territories appertaining to towns, and in particular took from Milan the little town of Monza, and the counties of Seprio and of Martesana, which the inhabitants had always regarded as their own property.
[1158-1161 A.D.]
Just motives had made the emperor and the diet consider these innovations necessary for the public peace and prosperity; but the Milanese regarded them only as perfidious violations of the treaty. When the podesta of the emperor arrived at Milan to take possession of the tribunal, he was sent contemptuously away. The Milanese flew to arms; and making every effort to repossess the different passes of the Adda, prepared to defend themselves behind this barrier. Frederick, on his side, assembled a new diet of the kingdom of Italy at Bologna, in the spring of 1159, and placed Milan under the ban of the empire.
The emperor did not yet attempt to reduce the Milanese by a regular siege. His army was neither sufficiently numerous to invest so large a town, nor his engines of war of sufficient force to make a breach in such strong walls; but he proclaimed his determination to employ all his power, as monarch of Germany and Italy, to ruin that rebellious town. The Milanese, accordingly, soon saw their corn mowed down, their autumn harvests destroyed, their vine stocks cut, the trees which covered their country either cut down or barked, their canals of irrigation broken; but the generous citizens of this new republic did not allow themselves to be discouraged by the superior force of such an enemy, or by the inevitable issue of such a contest. They saw clearly that they must perish; but it would be for the honour and the liberty of Italy; they were resolved to leave a great example to their countrymen, and to future generations.
The Siege of Crema
The people of Crema had remained faithful to the Milanese in their good and evil fortune; but the siege of that town presented fewer difficulties to the emperor than the siege of Milan. Crema was of small extent, and could be invested on every side; it was also more accessible to the engines of war, though surrounded by a double wall and a ditch filled with water. The Cremonese began the siege on the 4th of July, 1159; and on the 10th, Frederick arrived to direct it in person.[c]
The emperor regarded the inhabitants of the town as revolted subjects and he probably expected to have little difficulty in accomplishing their overthrow. Contrary to his expectations, however, the Cremascans proved not only brave but stubborn, and despite his best efforts they held out against him for about six months. The siege gave rise to many picturesque incidents and furnished typical illustrations of the methods of warfare of the time. Even before the first attack Frederick sought to frighten the Cremascans into submission by the barbarous execution of several of their citizens who had previously been sent to him as hostages. Nothing daunted, the inhabitants of the besieged city retaliated in kind; moreover, they gave proof of their intrepidity by sallying forth and attempting to defeat a portion of the besieging army in open combat. Their small numbers rendered this an act of hardihood, but it evidenced the spirit in which they were prepared to repel the assault.
