The opera-house was again brilliantly lighted. The Prince and Princess were there, and had been received as well as on the ninth, when, at about eleven o'clock, the Prince was called out of his box, and informed that bodies of from twenty to thirty of the Portuguese soldiers were parading the streets, breaking windows and insulting passengers in their way from barrack to barrack, where everything wore the appearance of determined mutiny. At the same time, a report of these circumstances having reached the house, the spectators began to rise for the purpose of going home; when the Prince, having given such orders as were necessary, returned to the box, and going with the Princess, then near her confinement, to the front, he addressed the people, assured them that there was nothing serious, that he had already given orders to send the riotous soldiers, who had been quarrelling with the blacks, back to their barracks, and entreated them not to leave the theatre and increase the tumult, by their presence in the street, but remain till the end of the piece, as he meant to do, when he had no doubt all would be quiet. The coolness and presence of mind of the Prince, no doubt, preserved the city from much confusion and misery. By the time the opera was over the streets were sufficiently clear to permit every one to go home in safety. Meantime the Portuguese troops, to the number of seven hundred, had marched up to the Castle-hill, commanding the principal streets in the town, and had taken with them four pieces of artillery, and threatened to sack the town. The field-pieces belonging to the Brazilians, which had remained in the town after the 26th of February, had been sent to the usual station of the artillery, at the botanical gardens, no longer ago than last week, so they entertained no fear of artillery. But they were disappointed in their expectation of being joined by that part of the Portuguese force which was stationed at San Cristovaŏ. This amounted to about 500 men[87], who said the King had left them to attend on the person of the Prince, and they had nothing to do with anything else; a declaration that was looked on with suspicion by the Brazilians. [Note 87: I am not sure of the correctness of these numbers, but I believe I am nearly right.] While the Portuguese were taking up their new and threatening position, the Brazilians were not idle. Every horse and mule in the town was pressed, and expresses despatched to all the militia regiments, and other Brazilian troops, as well as to the head-quarters of the artillery. The Prince was most active; so that by four o'clock this morning (12th), he found himself at the head of a body of four thousand men, in the Campo de Santa Anna, not only ready, but eager for action; and though deficient in discipline, formidable from their numbers and determination.
