It was some time before the details of Mentana were known in France. The government, it would appear, feared to acknowledge that the French soldiers took part in the engagement. When, however, the general’s report put an end to all doubt on the subject, there were no bounds to the rage of the revolutionary party. The revolution, hitherto, had used Louis Napoleon as a facile and valuable instrument. It could not pardon him Mentana. But France was not all revolutionary. The mass of the nation, honest and loyal, shared not the ideas of the secret societies. Far from regretting what had taken place, the French people dreaded lest there should not have been enough done. Cialdini, indeed, had been able to withdraw his troops, not with honor but without molestation, within the Italian frontier, whilst no account was required of his violation of the September convention. The ministers continued to discuss Italian unity as freely as they had been in the habit of doing for eight years, and the officious demagogue papers which were devoted to Prince Napoleon began to demand the speedy return of the French troops from Rome, and that by virtue of the famous convention which, according to these politicians, was binding on France, but not on Italy. The legislative body was moved. Not only the deputies who were declared Catholics, and who always divided against the government on the Roman question, but a great number of those also who had never until that time shown any indocility at the moment of voting, resolved to force the government to make a clear and public declaration of its intentions. The debate was opened by M. Thiers in an eloquent speech at the sitting of 4th December. He proved, and the proof was not difficult, that no reliance could be placed on the word of Victor Emmanual or Italian promises. “The House of Savoy,” said he, “goes to a falcon hunt with Garibaldi. If the latter fails he is taken to Caprera. If he succeeds, and takes a kingdom, they say to him, you are the revolution: your prey does not belong to you; it is ours, who are order and legality.” Jules Favre, a barrister, shamelessly spoke in a contrary sense, and endeavored to justify Italy. His sophistry met with no response.
