A military insurrection breaks out in the Asuncion garrison in the evening of May 14, 1811.

Plotters led by Captain Pedro Juan Caballero go to the Governor's quarters located on the main square of Asuncion, where they are greeted by second lieutenant Mauricio Jose Troche, a supporter of the plot, is on duty and in charge of the small garrison of thirty-four men from Curuguaty.

At midnight, Ensign Vicente Ignacio Iturbe presents Governor Velasco with demands from plotters led by Caballero, which can be summarized as follows:

    "Surrender of the main square, all the weapons and keys to the Cabildo."
    "Governor Velasco stays in power, but as a part of three-man junta, which should include two representatives appointed by the officers at the quarters."

A group of officers and politicians including Captain Pedro Juan Caballero, Fulgencio Yegros, Vicente Ignacio Iturbe, Mauricio Jose Troche, Fernando de la Mora, Juan Valeriano de Zeballos and José Gaspar Rodríguez de Francia, force governor Velasco to agree to a creation of a three-man executive junta.
