Francisco Bolognesi. Another hero of the War of the Pacific, and bequeather of a famous military axiom:

"When Chilean messengers demanded surrender of Arica because of their 3 to 1 numerical superiority, he replied, 'Tengo deberes sagrados que cumplir y los cumpliré hasta quemar el último cartucho' ('I have sacred duties to fulfill, and I will fulfill them until I fire the last round'). The expression 'hasta quemar el último cartucho' ('Until the last round is fired') has passed into the Spanish language."
