Campaign of Tacna and Arica

Meanwhile, Chile continued its advances in the Tacna and Arica Campaign. On 28 November, ten days after the Battle of San Francisco, Chile declared the formal blockade of Arica. On 31 December, a Chilean force of 600 men carried out an amphibious raid at Ilo as a reconnaissance in force, to the north of Tacna and withdrew the same day.
