In Valladolid he joined a group of independence conspirators, including his brother Nicolás, Captains
Manuel García Obeso and
Manuel Muñiz,
Ruperto Mier, Lieutenant
Mariano Quevedo, Licientiates
Soto Saldaña and
Manuel Ruiz de Chávez, Father
Vicente de Santa María, and Father Huango. Impelled by the news of the French occupation of Spain, the conspirators intended an armed revolution in
Celaya,
San Miguel el Grande, and
Zamora. Michelana was sent to
Guanajuato to recruit rebels there. This conspiracy was uncovered by the Spanish authorities on December 21, 1809. The conspirators were arrested and confined in the convent of El Carmen. Archbishop
Francisco Javier de Lizana y Beaumont, who was viceroy of New Spain at the time, ordered them brought to Mexico City so that he could speak to them. Their defense was that they were faithful patriots whose only intention was to preserve the country for King
Ferdinand VII, who had been forced to abdicate by Napoleon. They proposed to the viceroy (as related by Michelena) to form a junta to govern New Spain in the name of Ferdinand and to take all possible measures to extend the reign of this "august" sovereign. Lizana found no criminal offense in the conspirators, and ordered them set free, to the great disgust of the pro-Spanish party. Michelena returned to duty in Jalapa. ==War in Spain==
