Aquidaban (Paraguayan War).
The last stand of the Paraguayans against the allied armies of the Argentine Republic, Brazil, and Uruguay, May 1, 1870. Lopez, with a small force of Paraguayans and 5,000 Indians, met the attack of the allies under General Camera on the banks of the Aquidaban, and after a sanguinary engagement, in which he and the Vice-President Sanchez fell, his army was cut to pieces, and the war ended. During the war the population of Paraguay was reduced from 1,500,000 to 221,000, of whom only 29,000 were males over fifteen years of age.
