“Aim well, miliciano, for you defend the Republic.” On a barren hill in Asturias, Spain, near the border with León, José Fernández, a Loyalist soldier, etched this phrase into wet cement in September 1936, adding, “The Trench of Captain Lozano.” Written to commemorate a friend who'd been shot weeks before by Nationalist troops for refusing to desert the army of Spain's democratically elected government, Fernández's words remain visible in the rough stone 70 years later. They are a potent tribute to Lozano, a soldier who gave his life for the republic's ideals. But in today's Spain, there is a memorial even more powerful: the man named José Luis Rodríguez Zapatero, who, in addition to being prime minister, is Lozano's grandson.
