He received no command during the
Franco-Prussian War in 1870, because of his high age. He was nevertheless accused to have a part of responsibility in French defeat for having neglected to prepare for it during his second ministry and for having dissuaded
Napoleon III of acting in favour of Austria at the time of the
Battle of Sadova in 1866. Modern research has shown that the latter accusation is unfounded and that, quite contrarily, Randon had advocated an immediate action against Prussia. Randon died on 16 January 1871 in
Geneva, leaving one surviving daughter. The Marshal's first wife, Clotilde Périer, was a sister of
Casimir Périer, who had been President of the Council during the July Monarchy and the grandfather of
Jean Casimir-Périer, President of the French Republic. Marshal Randon later remarried to Zénaïde Suin. ==References==
