Spanish naval units shell the Chilean port of Valparaiso
As hostilities between a Peruvian-Chilean alliance and Spain continued, a Spanish fleet under Admiral Méndez Nuñuz carried out a three hour bombardment of the port of Valparaiso in the morning. The admiral had given warning and notice and most civilians had evacuated so casualties were low, with no confirmed deaths, although damage to facilities was quite heavy. (By John Osborne)
