The Holy Alliance (Russia, Austria and Prussia) refused Ferdinand's request for help, but the Quadruple Alliance (Britain, France, the Netherlands and Austria) at the Congress of Vienna in October 1822 gave France a mandate to intervene and restore the Spanish monarchy. On 22 January 1823, a secret treaty was signed at the congress of Verona, allowing France to invade Spain to restore Ferdinand VII as an absolute monarch. With this agreement from the Holy Alliance, on 28 January 1823 Louis XVIII announced that "a hundred thousand Frenchmen are ready to march, invoking the name of Saint Louis, to safeguard the throne of Spain for a grandson of Henry IV of France". At the end of February, France's Chambres voted an extraordinary grant for the expedition. Châteaubriand and the ultra-royalists rejoiced - the royal army was going to prove its bravery and devotion in the face of Spanish liberals, fighting for the glory of the Bourbon monarchy.
