What a month may bring forth is beyond our calculation; but while we were writing those pages, there had been a general movement of the Piedmontese troops on Verona, probably with the intention of aiding some insurrectionary movement in the city. The Piedmontese artillery speedily demolished the field-works in the approaches to the city. A general advance was ordered, and the Austrian troops continued to retreat, still turning on the advancing line, and fighting, through a country the greater part of which is a low shrubby forest. At length, however, a Piedmontese division was vigorously attacked, taken by surprise, and broken with a loss so heavy, as to determine the retreat of the army to its position of the morning. Still, this was but an affair of posts; and, in the mean time, General Nugent, with an army of 30,000 men, is putting down the insurgents in the Venetian provinces, and is marching towards the flank of the Piedmontese. One fact is evident, that Italy has _not_ risen in a body, and that, with all the harangues of her revolutionary orators, and all the promises of what those orators call "her heroic youth, burning to extinguish the abomination of the Teutons," very few of them have stirred from their coffee-houses. Italy, with her twenty millions of men, has probably not furnished to the field twenty thousand volunteers. Yet this is the time for which they have been all panting in all kinds of sonnets; when the "new spirit of political regeneration" has full range for its flight, when the Austrian police are a dead letter, and when Spielberg and its bastions are a bugbear no more. But the movements of the Roman populace are matters of more rapid execution. What the Pope was a month since, every one knows;--Pius the powerful, Pius the popular, Pius the restorer of liberty to all the aggrieved nations of Italy, with a slight appendix, including the aggrieved nations of Europe. But the populace, which gave him his titles, have now changed them, and he is "Pius the Monk." In a year whose every week produces a revolution, who can predict the events of a month? In the middle of this month of May, Pope Pius is virtually a prisoner in his palace; within a week he may be transferred to the castle of St Angelo; within a fortnight he may be an exile, an outlaw, or a refugee in England.
