After a period of consolidation in the three eastern provinces, the liberation armies headed for Camagüey and then for Matanzas, outmanoeuvring and deceiving the Spanish Army several times. The revolutionaries defeated the Spanish general Arsenio Martínez Campos, himself the victor of the Ten Years' War, and killed his most trusted general at Peralejo. Campos tried the same strategy he had employed in the Ten Years' War, constructing a broad defensive belt across the island, about long and wide. This line, called the "trocha", was intended to limit rebel activities to the eastern provinces, and consisted of a railroad, from Jucaro in the south to Moron in the north, on which armored railcars could travel. At various points along this railroad there were fortifications, at intervals of there were posts and at intervals of there was barbed wire. In addition, booby traps were placed at the locations most likely to be attacked.
