on the 15 February the Balmacedist commander, Eulogio Robles, who offered battle in the expectation of receiving reinforcements from Tacna, was completely defeated on the old battlefield of San Francisco. Robles fell back along the railway, called up troops from Iquique, and beat the invaders at Huara on 17 February, but Iquique in the meanwhile fell to the Congressional fleet on 16 February. Battle of Pozo Almonte The Pisagua line of operations was at once abandoned, and the military forces of the congress were moved by sea to Iquique, whence, under the command of Colonel Estanislao del Canto, they started inland. The battle of Pozo Almonte, fought on the 7th of March, was desperately contested, but Del Canto was superior in numbers, and Robles was himself killed and his army dispersed.

Some were driven into Peru, others into Bolivia, and one column made a laborious retreat from Calama to Santiago, in the course of which it twice crossed the main chain of the Andes.

The Blanco Encalada sank in a few minutes and 300 of her crew perished. This coup severely weakened the Congressional squadron. Congressional offensive The Revolutionary Junta, created on April 13, now firmly established in Iquique prosecuted the war vigorously, and by the end of April the whole area was in the hands of the "rebels" from the Peruvian border to the outposts of the Balmacedists at Coquimbo and La Serena. The Junta now began the formation of a properly organized army for the next campaign, which, it was believed universally on both sides, would be directed against Coquimbo. The necessary arms and ammunition were arranged for in Europe; they were shipped in a British vessel, and transferred to a Chilean steamer at Fortune Bay, in Tierra del Fuego, close to the Straits of Magellan and the Falkland Islands, and thence carried to Iquique, where
