The Spanish government was vigilant and strenuous. It sent more troops to Cuba, and it sent a large part of its navy to American waters, to patrol the Cuban coast, to cruise off the Florida coast, and to guard the waters between the two, in order to prevent the sending of filibustering expeditions or cargoes of supplies from the United States to Cuba. These efforts were so efficient that no important expeditions got through. But in spite of that fact an insurrection was started in Cuba in the spring of 1893. The leaders were two brothers, Manuel and Ricardo Sartorius, of Santiago de Cuba. On April 24 they put themselves at the head of a band of twenty men and, at Puernio, near Holguin, they proclaimed a revolution. The next day they were joined by eighteen more, and by the time they had marched to Milas, on the north coast, the band was increased to 300, while other bands, in sympathy with them, were formed at Holguin, Manzanillo, Guantanamo, and Las Tunas. This movement, however, was purely a private enterprise of the Sartorius Brothers; in which they presumably expected to be supported by a general uprising of the Cuban people. As a matter of fact there was no such uprising. The people seemed indifferent to it. The juntas and clubs in New York and elsewhere knew nothing about it. The Executive Committee of the Autonomist Party in Cuba adopted resolutions condemning it and giving moral support to the Spanish government, and the Cuban Senators and Deputies in the Cortes at Madrid took like action. Meantime the Spanish authorities in the island acted promptly and with vigor. The Captain-General summoned a council of war on April 27, and sent troops to the scene of revolt, and directed the fleet to exercise renewed vigilance to prevent aid from reaching the insurgents from the United States. The next day martial law was proclaimed throughout the province of Santiago de Cuba, and four thousand troops, divided into seven columns, were in hot pursuit of the revolutionists. The numbers of the latter rapidly dwindled through desertions and in a couple of days all had vanished save the two brothers and 29 of their followers. On May 2 these all surrendered, on promise of complete pardon, a promise which was fulfilled, and on May 9 martial law was withdrawn and the abortive revolt was ended.
