During the French Revolution, two Daughters of Charity, Marie-Anne Vaillot and Odile Baumgarten, were executed by firing squad for refusing to take an oath of loyalty to the state. Three sisters of their house did take the oath; Vaillot and Baumgarten were executed to intimidate the rest of the sisters in to following suit. As they were taken to the execution site, they inspired and strengthened their fellow prisoners and refused a last-minute offer that would have saved their lives. Other persecution of the Daughters of Charity is recounted.
