Although the Spanish forces were very considerably superior to the revolutionists numerically as well as in equipment and abundance of supplies, Calleja realized that they would not be sufficient to cope with the patriots on their own ground and in the increasing numbers which he prudently anticipated would rally to their standard. Accordingly early in March he sent to Spain an urgent call for large reenforcements for both army and navy, declaring that he could not hold his own, much less suppress the revolt, without them, and giving warning that unless he received them promptly he would not be responsible for the consequences. In response a battalion of regulars was immediately transferred to Cuba from Porto Rico, and 7,000 more were sent from Spain. All the civil prefects throughout the island were replaced with military officers. In Havana and elsewhere all prominent Cubans suspected of complicity or even sympathy with the revolution were arrested and imprisoned. The Morro Castle at Havana was crowded with the best citizens of the metropolitan province. But this attempt at repression only added fuel to the flame. The revolution burst out anew in the Province of Oriente, and when Callejas ordered the local troops of Havana to proceed thither, they mutinied and refused to go. In such circumstances Callejas, who at first had affected to regard the outbreak as mere sporadic brigandage, now openly confessed that it was an island-wide revolution. Complications with the United States also speedily arose. The arrest of Julio Sanguilly and others at Havana has been mentioned. These men had been in the United States for years, and had become naturalized citizens of that country, wherefore the United States consul-general at Havana, Ramon O. Williams, made formal demand that they should be tried before a civil court and should have the benefit of counsel, instead of being summarily disposed of by court martial. This was a legitimate demand, which had to be granted, but it incensed Callejas so much that he asked the Spanish government to demand Williams's recall; which that government very prudently did not do. At Santiago, also, two American sailors, who had landed there in a small boat, and had been arrested as filibusters, made appeal to the American consul there, who also insisted that they should have a civil trial; as a result of which they were acquitted.
