Ordinary Seaman Guillermo Jorge Peralta Pena was a Chilean sailor of the Royal Navy who died during the Second World War.
He was born the son of Alejandro Peralta Lopez and Luisa Pena de Peralta, of Villa Alemana, Chile.
Peralta Pena died on 21 January 1945, when the German U-boat U-1051 torpedoed the destroyer HMS Manners, resulting in the deaths of 43 crew and the stern of the ship being lost. Despite sustaining such grievous damage, Manners avoided sinking and returned to Britain under tow.
