Lopez and his men were welcomed at Key West with shouts of applause. Sympathizers with his expedition refused to consider it a failure. They declared that it had served to open the eyes of the Cubans to the fact that their deliverance was near, and that when Lopez once more set out with a larger force--as they assured him, with the assistance of the people of the south in the United States, he would--victory would be certain to spread her wings over his banner. So great was the popular clamor in favor of Lopez, that the United States authorities did not deem it prudent to arouse the ire of the mob, and therefore no attempts at arrest were then made. Indeed, little chance was given before debarkation, because in hardly more than ten minutes after the vessel had docked, the work of removing the wounded had been completed, and her decks were cleared of all men but seamen. The vessel was, however, seized by the authorities. When news of Lopez's exploits reached Madrid, the government was thrown into a great state of indignation, and promptly urged upon the United States the punishment of the offenders, stating: "If contrary to our expectations the authors of this last expedition should go unpunished, as did those who last year planned the Round Island expedition, the government of Her Majesty will find itself obliged to appeal to the sentiments of morality and good faith of the nations of Europe to oppose the entrance of a system of politics and of doctrines which would put an end to the foundations on which rests the peace of the civilized world. If Europe should sanction by her silence and acquiescence the scandalous state of affairs by which the citizens of the United States (or those of any power whatever) might freely make war from their territory against Spain, when the latter is at perfect peace officially with the Union; if it should be tolerated or looked on with indifference that the solemn stipulations which bind the two states should be with impunity made hollow by mobs and that the laws of nations and public morality should be violated without other motive than the selfishness of the aggressors, and with no other reliance than force, then civilized nations ought to renounce that peace which is based on the laws of nations and the terms of treaties and make ready for a new era in which might will be right, and in which popular passions of the worst kind will be substituted for the reason of states." Even with the government in Washington practically controlled by the pro-slavery interests, and with feeling in that quarter running high in favor of the filibusters, the United States, for the sake of preservation of peaceable relations with Spain, could hardly afford to ignore this protest. Hence, Lopez was arrested at Savannah, whence he had gone immediately upon his arrival on American soil, and a number of the leaders of his expedition were apprehended.
