Arsenio Martínez-Campos y Antón, born Martínez y Campos (Segovia, Spain, December 14, 1831 – Zarauz, Spain, September 23, 1900), was a Spanish officer, who rose against the First Spanish Republic in a military revolution in 1874 and restored Spain's Bourbon dynasty. Later he became Captain-General of Cuba. As soldier and politician, he took part in the wars in Africa, Mexico, Cuba and the last Carlist war.
Martínez Campos received a military education and after 1852 served on Spain's general staff (Estado Mayor). Later on, he was named professor in its academy. In 1860, he was sent to Africa, and also took part in the Mexican 1861 campaign against urban rebels under General Juan Prim, in a joint expedition along with France and Britain.
After the Revolution of 1868, Arsenio Martínez Campos requested posting to Cuba, where he fought well against the rebels in 1869 in the Ten Years' War, gaining the rank of Brigadier General. Success in this war commonly was a matter of perception, the Spanish Army after taking serious losses, would take the field in bayonet charges thus technically winning. However, the Cuban rebels would count up the Spanish losses against their own and consider the action a victory in terms of body count and withdraw. The Cubans also knew that movements of Spanish in the field caused the exposure of the susceptible Spanish forces to yellow fever and other tropical diseases; these diseases would hurt the enemy further. Martínez Campos, perceived as too soft to win, was displaced by the ruthless Blas Villate, Count of Balmaceda [1]; who proceeded with a brutal campaign of ethnic cleansing called, "The Rising Flood of Valmaseda". In 1872, Martínez Campos returned to Spain, where he backed the coup d'état led by Manuel Pavía. Here, he took charge of several brigades to fight the Carlist uprisings with little success. After this, he was put in charge of the Valencian army, fighting Independent forces in Alicante and Cartagena.
