As the father of the deceased prince was too old and his children too young, to give effectual aid to their cause, the Catalans might be now said to be again without a leader. But their spirit was unbroken, and with the same resolution in which they refused submission more than two centuries after, in 1714, when the combined forces of France and Spain were at the gates of the capital, they rejected the conciliatory advances made them anew by John. That monarch, however, having succeeded by extraordinary efforts in assembling a competent force, was proceeding with alacrity in the reduction of such places in the eastern quarter of Catalonia as had revolted to the enemy, while at the same time he instituted a rigorous blockade of Barcelona by sea and land. The fortifications were strong, and the king was unwilling to expose so fair a city to the devastating horrors of a storm. The inhabitants made one vigorous effort in a sally against the royal forces; but the civic militia were soon broken, and the loss of four thousand men, killed and prisoners, admonished them of their inability to cope with the veterans of Aragon.
At length reduced to the last extremity, they consented to enter into negotiations, which were concluded by a treaty, equally honourable to both parties. It was stipulated that Barcelona should retain all its ancient privileges and rights of jurisdiction, and, with some exceptions, its large territorial possessions. A general amnesty was to be granted for offences. The foreign mercenaries were to be allowed to depart in safety ; and such of the natives as should refuse to renew their allegiance to their ancient sovereign within a year, might have the liberty of removing with their effects wherever they would. One provision may be thought somewhat singular, after what had occurred ; it was agreed that the king should cause the Barcelonians to be publicly proclaimed, throughout all his dominions, good, faithful, and loyal subjects ; which was accordingly done!
The king, after the adjustment of the preliminaries, «declining,» says a contemporary, «the triumphal car which had been prepared for him, made his entrance into the city by the gate of St. Anthony, mounted on a white charger; and, as he rode along the principal streets, the sight of so many pallid countenances and emaciated figures, bespeaking the extremity of famine, smote his heart with sorrow. He then proceeded to the hall of the great palace, and on the 22nd of December, 1472, solemnly swore there to respect the constitution and laws of Catalonia.
