Night came, the enemy had entered Rome, and we who were in the castle--especially myself, who have always taken pleasure in extraordinary sights--stayed gazing on the indescribable scene of tumult and conflagration in the streets below. People who were anywhere else but where we were could not have formed the least imagination of what it was. T. ADOLPHUS TROLLOPE The combined force of Bourbon and Frundsberg was in all respects more like a rabble-rout of brigands and bandits than an army, and was assuredly such as must, even in those days, have been felt to be a disgrace to any sovereign permitting them to call themselves his soldiers. Their pay was, as was often the case with the troops of Charles V, hopelessly in arrear, and discipline was of course proportionably weak among them. Indeed, it seemed every now and then on the point of coming to an end altogether. The two generals had the greatest difficulty in preventing their army from becoming an entirely anarchical and disorganized mob of freebooters as dangerous to its masters as to everybody else. Of course food, raiment, and shelter were the first absolute essentials for keeping this dangerous mass of armed men in any degree of order and organization, and in fact the present march of Frundsberg and Bourbon had the obtaining of these necessaries for its principal and true object. The progress southward of this bandit army unchecked by any opposing force--for Giovanni delle Bande Nere had lost his life in the attempt to prevent them from passing the Po; and after the death of that great captain, the army of the league did not muster courage to attack or impede the invaders in any way--filled the cities exposed to their inroad with terror and dismay. They had passed like a destroying locust swarm over Bologna and Imola, and crossing the Apennines, which separate Umbria from Tuscany, had descended into the valley of the Arno not far from Arezzo. Florence and Rome both trembled. On which would the storm burst? That was the all-absorbing question. Pope Clement, with his usual avarice-blinded imbecility, had, immediately on concluding a treaty with the Neapolitan viceroy, discharged all his troops except a bodyguard of about six hundred men. Florence was nearly in as defenceless a position. She had, says Varchi, "two great armies on her territory; one that under Bourbon, which came as an enemy to sack and plunder her; and the other, that of a league, which came as a friend to protect her, but sacked and plundered her none the less." It was, however, probably the presence of this army, little as it had hitherto done to impede the progress of the enemy, which decided Bourbon eventually to determine on marching toward Rome.
