While thus careful to protect the rights of its citizens, native or naturalized, the United States government was equally energetic in its endeavors to prevent violations of the neutrality law by filibustering expeditions, and went to great expense and pains therein. It watched and guarded all Atlantic and Gulf ports to prevent the departure of such expeditions, and gave hospitality to a Spanish cruiser which lay at Key West to watch for and intercept them. Hannis Taylor, the American Minister at Madrid, assured the Spanish government that the United States would do all that was in its power to prevent such expeditions from departing from its shores, and that promise was fulfilled with exceptional efficiency. Indeed, the United States administration incurred much popular censure for its energy in stopping the sailing of vessels which were suspected of carrying supplies to Cuba; for it did stop a number of them, to the very heavy pecuniary loss of the patriots. Nevertheless some vessels were successful in eluding the vigilance of the federal guards, and that fact gave umbrage in Spain; so that while at home the American government was charged with hostility to the Cuban cause, in Spain it was charged with too greatly favoring it. With the receipt of reenforcements, Callejas made renewed efforts to suppress the revolution; though he had little heart in the matter and seemed to realize the hopelessness of the task. Practically all the fighting was in Oriente. Colonel Santocildes made an unsuccessful attack upon the patriots near Guantanamo on March 10, and a week later Colonel Bosch had an equally unsatisfactory meeting with them under Brooks and Perez near Ulloa. So strong were the insurgents becoming in that province that they began to exercise the functions of civil government, in the carrying of mails and the collection of taxes. Beside Henry Brooks and Perico Perez, under whom were the largest forces, Bartolome Maso, who had returned from Havana, held Manzanillo with a thousand troops, Jesus Rabi occupied Baire and Jiguani with 1,500, and Quintin Banderas, Amador Guerra and Esteban Tomayo had among them 2,000 more. After his repulse at Guantanamo the Spanish Colonel Santocildes went to Bayamo, where he was attacked and routed with heavy loss. A few days later, on March 24, a battle was fought at Jaraguana between Amador Guerra, with 900 Cubans, and Colonel Araoz, with 1,000 Spanish regulars, in which the latter suffered the heavier losses, though they finally compelled the Cubans to retire from the field.
