Colonel Ramón Maza, Manuel Vicente Maza's son,…

Manuel Vicente is assassinated on June 27 by a group of men armed with knives who surprise him in his office, presumed to be while Maza is writing a letter to Rosas, begging for his son's life.

Hours after the senior Maza's assassination, his son Ramón is executed in his cell under Rosas' orders.

Mercedes Puelma Díaz Andrade de Maza, Ramon's mother and Manuel Vicente's wife, commits suicide short after.

Maza's assassination may be the first of a series of crimes by La Mazorca, in an attempt to eliminate Rosas' potential enemies.

José María Paz had meanwhile received the privilege of freedom in April 1839, under oath of keeping away from Rosas' opponents.
