On July 24, 1833, the Callao Battalion[1] and several squadrons of the Hussars of Junín regiment[2] rebelled in Ayacucho under the command of Captains Alejandro Deustua and Tomás Flores, assassinating the prefect, Colonel Juan Antonio González, and the head of the military department, Colonel Mariano Guillén, and rebelled on the side of the Iquichans.

[2] On August 15 they confronted Generals Pedro Pablo Bermúdez and Miguel de San Román and the Piquisa Battalion[3] in Pultunchara.

[5] For this reason, in the Peruvian Civil War of 1834, the Iquichans supported the liberal president Luis José de Orbegoso against the coup of the conservative generals Pedro Pablo Bermúdez[6] and Agustín Gamarra, a key figure in politics of the time, and an enemy of the republiqueta.

[8] After defeating the revolt in the capital, Orbegoso had to face Gamarra in the southern highlands of the country seeking an alliance with the inhabitants of Huanta.

Finally tired of the conflict, after several confrontations, the Yanallay Treaty was signed on November 15, between the prefect of Ayacucho, Colonel Manuel Lopera, and the guerrilla Tadeo Choque (or Chocce).
