[Santiago Ramón y Cajal: his activity as a military doctor (1873-1875)]

Santiago Ram n y Cajal entered the Medical Corps after graduating in Medicine in 1873. His marked Spanish nationalist character and his excellent physical condition led him to serve in the third Carlist war as a medical lieutenant and later in the Cuban War as a captain. His stay in Cuba, however, was marked by hardship and illness. The decline of Spain s colonialist policy, the war that was fought in a hostile climate and atmosphere, and the corruption of the military officers led to Santiago being posted to the frontlines on a fixed logistics system of trails. All this was to end in military failure and the subsequent loss of the colony. Disillusioned and seriously ill from malaria, which nearly killed him, he returned to Spain after being discharged for illness. Shortly afterwards, thanks to Dr. Jenaro Casas, he became a university lecturer, which put an end to his military career
