Notwithstanding this surrender, Guidobaldo advanced upon the city, quartering his troops in the surrounding villages, so as to blockade it, and all the public functionaries were superseded. Dreading a sack, the citizens rushed to the monasteries with their valuables, and, about the middle of February, sent fifty of the nobles to crave pardon of their sovereign. After waiting at Pesaro for three days, these were admitted to tender submission on their knees, and were then placed under arrest at their inn for twenty days, notwithstanding incessant petitions from their fellow citizens for their release. Six of them were then committed to the castle, and from time to time other leaders were brought from Urbino to share their imprisonment. So terrified were the insurgents by these measures, that those most compromised fled from the duchy, and but few remained in their houses; a proclamation was therefore issued that all exiles should return home within two months, under penalties of rebellion. The property of the prisoners and exiles was confiscated; the city was disarmed; public assemblies were prohibited; and the magistracy were discharged from their duties.[69] Such rigorous measures having inspired a general panic, the imposts were again proclaimed at Easter, to include retrospectively the previous year. These severities were perhaps scarcely beyond the exigencies of the case; at all events, they cannot be justly regarded as an extreme exercise of the despotic authority which the Duke undoubtedly possessed; but those which ensued must be viewed with abhorrence, alike from their own enormity, and from their prejudicial influence in confounding vengeance with justice. [Footnote 69: The magistrates of Urbino were four in number, a gonfaloniere chosen from the city nobles, a prior to represent the merchants, and two priors of the trades. The general council seems to have been open to all citizens.]
