YANEZ, Placido (yahn'-yayth), Bolivian soldier, born in Cochabamba about 1820; died in La Paz, 23 November, 1861. He had served from early life in the army, and by his frequent participation in revolutions rose rapidly in rank, being promoted brigadier in 1861 by President Jose Maria Acha. Soon he became infamous by his ferocity and the cruel slaughter of the most noteworthy citizens of the republic. During the absence of General Acha from the capital Yariez was the military commandant and minister of war, and on 23 October, 1861, under pretext of having discovered a conspiracy against the government, he attacked the defenceless city with his troops, and, driving the principal persons into the square of Loreto, shot down and slowly murdered in cold blood more than fifty, among them Generals Cordoba and Hermosa. But on 23 November of the same year a popular revolt began, and an infuriated multitude demanded his head. Knowing his peril, he took refuge in the government palace with a few sharp-shooters, and failing to obtain relief from the garrison of the citadel, which fraternized with the populace, he tried to escape over the roofs, but was discovered. Falling from the roof of the palace, he was crushed on the pavement, and his body was torn to pieces by the infuriated people.
