Armée de la Foi
The "Hundred Thousand Sons of Saint Louis" was the popular name for a French army mobilized in 1823 by the BourbonKing of France, Louis XVIII, to help the Spanish Bourbon royalists restore King Ferdinand VII of Spain to the absolute power of which he had been deprived during the Liberal Triennium. Despite the name, the actual number of troops was between 60,000 and 90,000.
A minor campaign, the force comprised some five army corps (the bulk of the French regular army) and was led by the Duke of Angoulême, nephew of Louis XVIII and son of future King Charles X. The French name of the conflict is l'Expédition d'Espagne ("the Expedition of Spain").
