Maceo, with the experience and wisdom gained from previous revolutionary failures, argued that there were a number of impediments to military success in a brief but intense epistolary exchange with Martí, warning about the causes of the partial defeat in the Ten Years' War (1868–78). Martí responded with his formula of “the army, free; but the country, as a country with all its dignity represented,” and convinced Maceo of the high probabilities of success if the war was to be prepared carefully. As a precondition, Maceo demanded that highest command should be in the hands of Gómez, which was approved without reservation by the Delegate of the Cuban Revolutionary Party (Martí). In Costa Rica, he faced, gun in hand, another attempt of assassination by Spanish agents at the exit of a theatre, with fatal result for one of the aggressors. Cuban War of Independence In 1895, together with Flor Crombet and other lesser officers, Maceo disembarked in the vicinity of Baracoa (close to the eastern tip of Cuba) and after repelling a Spanish attempt at capturing or killing him, he got into the mountains of that region. After many difficulties, he managed to gather a small contingent of armed men, which rapidly grew with other rebel groups of the Santiago de Cuba region. In the farm of "La Mejorana", Maceo had a historic, but unfortunate, meeting with Gómez and Martí, because of the disagreements between him and Martí, regarding the question of the relationship between the military movements and the civilian government, against which constitution was Maceo, but Martí, knowing both sides of the problem, stood on his formula. Several days later, Martí, treated as a non-military “Doctor” by Maceo, would fall in battle in Dos Ríos (confluence between the rivers Contramaestre and Cauto). After Gómez was designated General in Chief of the Cuban Liberation Army, Maceo was named Lieutenant General (second in command after the General in Chief). Starting from Mangos de Baraguá (place of the historical protest in front of Martínez-Campos), Maceo and Gómez, on command of two long mambises columns, took brilliantly the task of invading the west of Cuba, riding or walking more than 1000 miles in 96 days. After several months bleeding the Spanish forces in Havana and Pinar del Río Maceo arrived at Mantua, in the western extreme of Cuba, in October 1896, after defeating for many times the technically and numerically superior forces
