An immense camp was pitched in the midst of the vast plain which is watered by the Po; in the centre stood the Imperial tent, and around it, in order of rank, those of the princes. Streets at right angles divided the various quarters of this city of canvas, and to avoid all danger of collisions, the Germans and Italians were encamped on opposite sides of the river. Frederic had invited four of the most celebrated juris consults of Bologna, and had given them as coadjutors twenty-eight counsellors from the other Lombard towns, in order to investigate and define thoroughly the origin and spirit of their statute laws and their oral traditions.
From his throne, Frederic opened the assembly with a solemn discourse.
"Called to the supreme power, by the grace of God," said he, "our task is to elevate the courage of the good, to restrain and punish the evil-doer. At the close of the late campaign which we have terminated so fortunately; the pacification of the country demands our earnest attention, for it is only simple justice that we should protect, by our arms, the people who are governed by our laws. But before anything be written, or decided concerning our respective rights, duties, and privileges; we must establish what is equitable and expedient, necessary and useful, according to the locality and the epoch; for once these laws adopted and promulgated, there will be no further discussion admitted in the matter, they will be rigidly and exactly enforced."
The Italians were astonished at the ability of the young monarch. His talents and his policy compelled their respect, for it became evident that under such a ruler, their only safe course of action would be implicit obedience.
Whilst the Bolognese legists insisted upon privileges being accorded to the Emperor, based upon the old Roman law, the Lombard counsellors complained of an autocratic despotism, in the decisions, subversive of their own peculiar rights, and inimical to the interests of their country. For example, all revenues from tolls on rivers and bridges, and tonnage dues in ports and harbors, were to revert hereafter to the Emperor; and all duties on grain, salt works, and fisheries, with the right of coinage, hitherto a prerogative of the dukes, counts, and free cities, were in future to belong exclusively to the Imperial treasury.
Barbarossa had destroyed the autonomy of the Lombard cities, and reduced them to be mere dependencies of the empire. Still, so long as he remained in Upper Italy, no open signs of discontent were manifested, but scarcely had he turned towards Rome, when the revolt broke out. In order to pacify, if possible, the malcontents, Otto de Wittelsbach; the Chancellor Rinaldo, and the Knight of Goswin were at once sent to Milan. But the exasperated populace assembled before the dwelling of the ambassadors, who with much difficulty escaped being torn to pieces.
This unexpected outrage excited the rage of the German nobles who accompanied the Emperor, and the rebellious city was threatened with sack and pillage, while its inhabitants were doomed to slavery. This fierce menace, however, by no means disheartened the Milanese, who determined to employ every means of resistance in their power, and to die gloriously rather than wear the fetters of serfdom. The struggle began at once, and while Barbarossa was celebrating the festival of Easter at Bologna, the Lombards seized the Imperial treasury, in which were lodged the enormous sums which he had collected in Italy. Then they burned the castle and hung all the garrison, who were Italians, as traitors to their country.
The Emperor hastened back with his little army, but he arrived too late; the Milanese had retreated behind their works, and from the walls of the city could see Frederic, in his anger, lay waste all the surrounding country; for, weak in numbers and destitute of siege artillery, his army was powerless against the town. Scarcely had he left the neighborhood, when the Lombards took up again the offensive, and retaliated upon the Emperor's allies for the havoc which he had caused in their territory. Joining their forces to those of the Brescians, they took Lodi and Cremona, and made several attacks upon the Imperialist forces; and such was the vindictiveness displayed; that several abortive attempts were made to assassinate the German Emperor, who was unable to check or punish these acts of hostility. His army was composed almost entirely of Italians, and although the rebellious city of Cremona was taken and burned, his reprisals were without result.
This continual strife and its attendant misfortunes, equally disastrous for both factions, reduced Lombardy almost to a desert. The devastated fields produced no more crops, and the ground being unable to sustain even the native population, the foreign troops suffered severely from famine. Barbarossa convoked again his knights and nobles, thanked and rewarded them publicly for their devotion to his cause, and disbanded the Germans, promising to open the campaign with a strong army, early in the following spring.
