In November, 1896, he took part in the battles of Alta Conchita and Lugones against Gen. Pando. Later he was present at the siege of Jiguani (April 13, 1897) and at Tuaheque, Jacaibama and Jucaibanita against Vara del Rey and Nicolas Rey, and at Baire he fought at the battle of Ratonera. It was at this time that Gen. Calixto Garcia made him Chief of the 3rd Division of the 2nd Corps, which included the western part of Holguin and Tunas. At the head of these forces he organized the attack and capture of Tunas, which was achieved by Gen. Calixto Garcia, August 30, 1897, Menocal having been wounded in a trench assault. This strategic success won for him an immediate promotion to Division General. In November, 1897, he attacked Fort Guamo on the Cauto River, one of the bloodiest events of the war, and took part in the battles of Cayamos, Monte Oscuro, Nabraga and Aguacatones, succeeding in this latter in seizing Tejeda's supply train. In March, 1898, he was appointed Chief of the 5th Army Corps, to join which he marched at the head of 200 select men, among whom were many prominent figures of the war--many still alive--as General Sartorius, Colonels Aurelio Hevea, Enrique Nunez, Federico Mendizabal, Pablo, Gustavo and Tomas Menocal, Rafael Pena, Carlos Manuel de Cespedes, Commander Manuel Secades, Miguel Coyula, Ignacio Weber, Alberto de Cardenas, Antonio Calzades and Domingo Herrera. With this brave contingent, and assisted by the forces of Gen. Agramonte, Gen. Menocal passed the Trocha at its most dangerous point between Ciego de Avila and Jucaro. After a fifty days' march from Holguin, they reached Havana, relieving Gen. Alejandro Rodriguez of his command as Chief of the 5th Army Corps. Gen. Menocal was in this command when the American Intervention came, and cooperated with the American authorities in maintaining public order in Havana while the evacuation of the Spanish troops took place. Then General Ludlow appointed him Chief of the Havana Police, which body he organized, giving posts under him to the most distinguished chiefs of the Province of Havana. In 1899 he was appointed Inspector of Light Houses and subsequently Inspector of Public Works, which offices he resigned to manage Central Chaparra, in June, 1899.
