Presidential palace
During the military coup organized by Hugo Chávez on 4 February 1992, Blanca, her daughters and granddaughters were in residence at the Presidential palace of La Casona whilst it was besieged by rebel forces. While her husband managed to escape and quell the coup attempt, Blanca remained at La Casona during the particularly heavy attack. She later made sure to assist in the tending of wounded soldiers, regardless of their allegiance, and was crucial in keeping morale up during the few hours when it seemed the residence was going to be taken.
