Martí was killed on 19 May 1895, during a reckless charge against entrenched Spanish forces, but Máximo Gómez (a Dominican) and Antonio Maceo (a mulatto) fought on, taking the war to all parts of Oriente. Gómez used scorched-earth tactics, which entailed dynamiting passenger trains and burning the Spanish loyalists' property and sugar plantations—including many owned by Americans. By the end of June all of Camagüey was at war. Continuing west, Gómez and Maceo joined up with veterans of the 1868 war, Polish internationalists, General Carlos Roloff and Serafín Sánchez in Las Villas, swelling their ranks and boosting their arsenal. In mid-September, representatives of the five Liberation Army Corps assembled in Jimaguayú, Camagüey, to approve the Jimaguayú Constitution. This constitution established a central government, which grouped the executive and legislative powers into one entity, the Government Council, which was headed by Salvador Cisneros and Bartolomé Masó.
