This seems perhaps an elaborate organization for so small a force, but it must be borne in mind that Lopez and his followers firmly believed that this time there was to be no repetition of the former lack of enthusiasm on the part of the Cubans, but that they had only to land to be greeted with rejoicing, and to have flock to their assistance a great number of Cuban patriots. This impression was increased by forged letters--which Lopez, however, accepted as genuine--which were waiting for them at Key West and which are now believed to have been written by a follower of Lopez in Havana, under duress and intimidating threats of Captain-General Concha, for the latter having learned of the expedition resorted to treachery to thwart the plans of the filibusters. These letters intimated that Pinar del Rio and many cities in that vicinity were in open revolt against Spanish rule, and prayed that Lopez come quickly to the aid of the rebels, who were eager to join him. Colonel Crittenden, in command of the artillery regiment, was a man of the highest connections in the United States. He was a seasoned soldier, being a veteran of the Mexican war, and having received his training at West Point. In Lopez's band were also several officers from the United States Custom House at New Orleans, and many men from the best families of the South. On April 7 the smoke of a steamer was seen in the distance, and it soon seemed to indicate that the _Pampero_ was being pursued. Her course was changed, and she either succeeded in outdistancing her pursuer, or the latter decided that a mistake had been made in the identity of the vessel, and abandoned the chase. The expedition neared Key West, and they expected to find there United States vessels of war, and a strong garrison. Therefore an attempt was made to disguise the character of the _Pampero_ and her purpose, and the men were all ordered below. Lopez was delighted to find that his anticipations were wrong, for there were no men of war in the harbor and the barracks were empty. As the _Pampero_ docked, and the men came on deck, they were greeted by a shouting mob of enthusiastic people. They were welcomed as heroes, and the inhabitants came on board bearing food of the most tempting variety and cases of champagne. A feast followed, at which the health of the filibusters and the success of the expedition was drunk with shouts of approval.
