Martínez Campos could not bring himself to launch the process of reconcentración against an enemy he saw as honorable. He wrote to Spain and offered to surrender his post rather than impose the measures he had laid out as necessary. “I cannot,” he wrote, “as the representative of a civilized nation, be the first to give the example of cruelty and intransigence.”

Spain recalled Martínez Campos, and in his place sent general Valeriano Weyler, nicknamed “the Butcher.” There was little doubt about what the results would be. “If he cannot make successful war upon the insurgents,” wrote The New York Times in 1896, “he can make war upon the unarmed population of Cuba.”

Civilians were forced, on penalty of death, to move into these encampments, and within a year the island held tens of thousands of dead or dying reconcentrados, who were lionized as martyrs in U.S. newspapers. No mass executions were necessary; horrific living conditions and lack of food eventually took the lives of some 150,000 people.
