Nicanor Flores (29 January 1820 – 14 July 1892) was an Argentine-born Bolivian military officer who rose to prominence during the presidency of José María Linares.

In an act of cruelty, Flores entered the town making and hunted the persecuted like animals, brutally murdering most of the rebels and taking five prisoners; they were executed soon thereafter.

[1][2] After Linares was toppled in 1861 by José María de Achá, Flores revolted in Sucre alongside General Pedro Olañeta and Colonel Agustín Morales and proclaimed the Argentine Ruperto Fernández as President.

The city was ready for the fight and had received some reinforcements from Sucre;[7] however, misunderstandings and disagreements among the revolutionary leaders Generals Flores, Achá, Sebastián Ágreda, Ildefonso Sanjinés,[8] and Casto Arguedas, were greatly detrimental to the cause.

These disagreements came to favor Melgarejo, who, after penetrating the barricades of the Potosí, massacred a handful of young men, among them the famed Bolivian poet Néstor Galindo, and defeated the rebels at the Battle of Cantería.

However President Hilarión Daza, reinstated Flores into the army and invited him to represent Bolivia to the Agua Santa council of chiefs, where the defense of San Francisco was discussed.

When Daza was deposed by General Campero, Flores offered his services to the new government, having been appointed Superior and Political Chief of the South, where, hoping for the victory of the allied army, he raised a war loan with which he bought weapons and ammunition.

After the National Convention of 1880 would award him a gold medal for services rendered to the republic during the war with Chile, Flores retired from the army sometime around 1882, heading to Argentina in 1883.
