The ultras broadened their support, and put a stop to growing military dissent in 1823, when intervention in Spain, in favour of Spanish Bourbon King Ferdinand VII, and against the Liberal Spanish Government, fomented popular patriotic fervour. Despite British backing for the military action, the intervention was widely seen as an attempt to win back influence in Spain, which had been lost to the British under Napoleon. The French expeditionary army, called the Hundred Thousand Sons of Saint Louis, was led by the duc d'Angoulême, the comte d'Artois's son. The French troops marched to Madrid and then to Cadiz, ousting the Liberals with little fighting (April to September 1823), and would remain in Spain for five years. Support for the ultras amongst the voting rich was further strengthened by doling out favours in a similar fashion to the 1816 chamber, and fears over the "charbonnerie", the French equivalent of the "carbonari". In the 1824 election, another large majority was secured.
