The Portuguese were inclined to resist, when Dom Pedro himself appeared in their midst and ordered their commanders specifically to embark the next day and to sail for Portugal. He had now decided on his attitude, and was determined that his orders should be obeyed. To show that he was in earnest he even took a match in his hand and lit it, and swore that, did the Portuguese troops refuse, he would be the first man to fire a cannon at them. This ended the matter, and the next day the ship sailed and carried away the Portuguese garrison. [Illustration: CHAMBER OF DEPUTIES, RIO DE JANEIRO.] On May 13, 1822, a deputation from the Rio Chamber of Deputies approached Prince Pedro and persuaded him to assume the title of "Constitutional Prince Regent and Perpetual Defender of Brazil." Portugal, for its part, was now bitterly opposed to Brazil and to the Brazilians. Decrees were enacted towards the suppression of the independence of the great colony. One of these ran to the effect that Prince Pedro was to return to Europe within four months, and that any of the military who obeyed his orders, unless by compulsion, were to be deemed traitors to Portugal. During all this time fresh troops were arriving to reinforce the garrison at Bahia, which had remained Royalist. The patriots, for their part, had collected strong forces and hemmed the Royalists in Bahia to such an extent that they could only retain communication by sea. Matters grew more and more strained every day, for the Mother Country sought to put an end to the virtual supremacy of its great colony, while Brazil was utterly opposed to Portuguese rule. When Prince Pedro was ordered to return to Portugal, "in order to complete his education," the Brazilians, and especially the provincial Government of Sao Paulo, begged him to disobey and remain in Brazil. The soldiers threatened to mutiny if he went, and the people entreated him not to go, while every proof of his popularity was added cause for exasperation on the part of the Home Government, rendering his situation more dangerous.
