During the Battle of Morro de Arica on June 7, 1880, there were thousands of casualties among the Chilean and Peruvian armies, all of whom died in less than one hour of conflict. About 100 years later the skeletal remains of a soldier was uncovered. The Rock of Arica Crypt on top of El Morro honors him and the others who sacrificed their lives. Interestingly, a Peruvian soldier who was spared that day and taken prisoner was Roque Sáenz Peña. He went on to become the President of Argentina from 1910 until 1914.
