It was estimated that by this time Spain had sent to the island in the neighborhood of sixty thousand trained soldiers, but they had come few at a time, and on no occasion in larger numbers than two or three thousand. Evidently the Spanish Government had at no time properly estimated the strength, if not in numbers, at least in valor and determination of the insurgents, and had never realized that only by investing the island with overwhelming superiority could they hope to put down the rebellion. However, during all this time Spain had been struggling against disturbances at home of no mean dimensions, and early in the year 1872 she was to endure another revolution, and the abdication of Amadeus, followed once more by a republican form of government. Records compiled by both sides prove that the war continued during the year 1872 with the same persistence, unchanged in character, and apparently no nearer a decision. The Spanish government, both at home and abroad, seems to have suffered at this time from great apprehension that the United States government would officially recognize the Cubans as belligerents, in which event their position would be materially strengthened. In February Spain sent more troops to Cuba, at the request of Captain-General Valmaseda, who accompanied his appeal by a statement—for publication, and to impress the United States—that the war would be over by April or May.

March found the struggle continuing, and on March 5, General Cespedes himself, with a large body of Cuban troops, succeeded in taking Sagua de Tanamo by storm. In this same month aid came from the United States, for the steamer Edgar Stewart arrived with arms, ammunition and supplies for the Cuban army.

Small engagements took place all during April, and in May the Cuban leaders issued a statement to the effect that if Valmaseda was expecting that the war would soon be ended, he was not taking into consideration the strong resistance which the Cubans were still able to offer, and which they intended to continue until Spain granted them independence. Truly the war might end at once, but Spain would end it not by force of arms but by acceding to the frequently expressed desire of Cuba for complete separation from her rule, by withdrawing the offensive government, and by transporting her troops back to their native land.

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.

The close of the year 1872 registered a splendid victory for the patriots, when on December 20 they stormed and took Holguin, and captured large quantities of supplies of all kinds.

Public documents compiled by the Spanish in August, 1872, estimated the losses of the patriots up to that time as "thirteen thousand six hundred insurgents—and a large number taken prisoner" while "sixty-nine thousand six hundred and forty were in submission to the government; our thousand eight hundred and forty-nine firearms, three thousand two hundred and forty-nine swords and bayonets, and nine thousand nine hundred and twenty-one horses were captured."
