Amphibious warfare during the War of the Pacific of 1879 to 1883 saw coordination of army, navy and specialized units. The first amphibious assault of this war took place during the Battle of Pisagua when 2,100 Chilean troops successfully took Pisagua from 1,200 Peruvian and Bolivian defenders on 2 November 1879. Chilean Navy ships bombarded beach defenses for several hours at dawn, followed by open, oared boats landing army infantry and sapper units into waist-deep water, under enemy fire. An outnumbered first landing-wave fought at the beach; the second and third waves in the following hours succeeded in overcoming resistance and moving inland. By the end of the day, an expeditionary army of 10,000 had disembarked at the captured port.
