Meanwhile, the daring attack upon Cardenas, while it demonstrated the determination of the invading party, caused great anxiety in the mind of General Roncali. True, he had at his disposal an army of more than twenty thousand regular troops; but he was by no means sure of their loyalty, and he therefore determined to raise a local militia; but, as he suffered only Spaniards to enlist in it, he aroused the jealousy of the Cuban-born inhabitants, and thus swelled the force of opposition against the government. General Lopez was informed of this fact, and based new hopes upon the circumstance. The Spanish government, having recalled Roncali, appointed Don José de la Concha captain-general of the island, and the severity of his sway reminded the inhabitants of the iron rule of Tacon. It was during his administration that Lopez effected his second landing at Playitas, sixty miles west of Havana. Several partial insurrections, which had preceded this event, easily suppressed, as it appears, by the Spanish government, but exaggerated in the accounts despatched to the friends of Cuba in the United States, inflamed the zeal of Lopez, and made him believe that the time for a successful invasion had at length arrived.[9] He was so confident, at one time, of the determination and ability of the Cubans alone to secure their independence, that he wished to embark without any force, and throw himself among them. It was this confidence that led him to embark with only four hundred ill-armed men on board the little steamer Pampero, on the 2d of August, 1851. This force consisted mostly of Americans, but embraced forty-nine Cubans in its ranks, with several German and Hungarian officers; among the latter, General Pragay, one of the heroes of the Hungarian revolution, who was second in command to General Lopez on this occasion.
