Another round bursts from the guided missile frigate USS Doyle's saluting battery as Gunner's Mates render a time-honored 21-gun-salute to the entombed Chilean sailors in the sunken 19th warship, turned memorial, Esmeralada. The captain and crew of the Esmeralda are national maritime heroes for their courgage and determination to never surrender their ship during the Battle of Iquique in the late 1800's War of the Pacific between Chile and the combined forces of Peru and Bolivia. Doyle is on a six-month deployment to the 4th Fleet Area of Operations in support of US Southern Command's Southern Seas 2009 Partnerships of the Americas strategy.
