The Granada was armed with two six-pound carronades and was placed in charge of Lieutenant Callender Irvine Fayssoux. This officer was a native of Missouri, and had served for a time in the Texan navy under the orders of Commodore Moore. He had also accompanied Gen. Lopez in his expedition to the Island of Cuba in May, 1850; and at Cardenas he had contributed essentially to the successful landing of the force from the steamer Creole, by swimming ashore with a rope in his mouth when there was much embarrassment as to the means of getting the boat up to the wharf. His high qualities will hereafter appear when we come to relate the history of the schooner; and it is only necessary here to say, that his system and order were such, the Granada was ready for service in a very short time. The men detailed from different companies of the army for service on the schooner were soon brought under good discipline by their efficient commander; and all of them felt they were subject to the orders of one capable of command, and determined to have each man do his duty on all occasions. On the 29th of June, Col. John Allen of Kentucky arrived at Granada with one hundred and four men for the service of the State; and on the 6th of July about the same number were landed coming from New-York, from New-Orleans and from California. A day or two after the latter arrival, Major Waters, with about a hundred Rangers, marched to Leon and reconnoitred the town. He found it barricaded in every quarter, and the Guatemalans under General Paredes were occupying the main Plaza. On the approach of Waters all the pickets of the enemy were drawn in, and their whole force was put under arms for action. But no portion of the enemy ventured to leave the barricades. After passing through the suburbs of the city and examining the preparations of the enemy for defence, Waters returned to Granada with a report showing the inability of the Allies—as they called themselves—to move until they had received large additions of force.
