Early in June the Cubans defeated the Spaniards near Las Tunas, and on the 9th of that month, after heavy fighting, took Sama. The Cuban losses in these engagements were heavy in comparison with the number of men involved, but they were able to comfort themselves with the knowledge that the Spanish killed and wounded totaled a much greater number, for while the Cubans had only fifty killed and less than a hundred wounded, the Spanish left dying on the battle field more than four times as many as the Cubans, and their wounded amounted to three hundred and fifty. But the Spanish navy was able to capture an expedition bearing relief to the Cubans, and to defeat a band of patriots at Holguin, so that it would seem that the honors for the month were about equal.
In July, General Garcia attacked Spanish troops under the Governor of the Province, Colonel Huertas, and a very hot fight resulted, in which the victory fell to the Cubans; and when Spanish reinforcements arrived, they too were routed and put to flight. But this was offset by the fact that General Inclan, one of the bravest and most loyal of the Cuban commanders, as well as an expert tactician, fell into the hands of the enemy, and was summarily executed at Puerto Principe.
Count Valmaseda, Captain-General, now ran foul of the displeasure of the Volunteers, and suffered a downfall in consequence. On July 15 he was recalled, and General Ceballos served in his place until the arrival of his successor, Don Joachim Jovellar.
It now seemed time again for the Spaniards to assert themselves against defenseless sympathizers with the revolution. Spies were busily at work in Guira, Jiguani and Holguin, and presently they purported to discover grave disloyalty among the members of some of the well known Cuban families. This was the signal and the excuse for a wholesale slaughter of innocent unoffending people, who, whatever their feelings, had taken no active part in the uprising. As a means of reprisals the Cubans made an attack on Guira, but it was not entirely successful.
The people of the United States were now following the insurrection with much interest, particularly in those portions of that country in which there were large numbers of sympathizers, and they were no longer willing to ignore well authenticated reports of Spanish cruelty. A State Convention of the Republican party was held at Jacksonville, Florida, where there were many who were friendly to the Cuban patriots, and adopted a resolution, denouncing the action of the Spanish authorities in Cuba as cruel and inhuman, and calling upon Congress to pass the necessary legislation to make it possible for the United States government to extend such aid to the Cubans as "becomes a great and free republic, whose people so ardently sympathize with the struggles and hopes of the oppressed of all nations." However, the Government at Washington did not look with favor upon this suggestion, and ignored it, and it had little effect in stemming the tide of Spanish oppression in Cuba.
