In attempts to retain or re-assert control over its colonies in America, the Spanish Empire deployed several expeditionary forces during and after the Spanish American wars of independence. The largest of these forces, known as "the expeditionary army of Costa Firme", and consisting of over 10,000 troops under General Morillo, undertook the Spanish reconquest of New Granada (1815–16).Lynch, Spanish American Revolutions, 209.

Forces were also sent to New Spain between 1812 and 1817.Small contingents from Spain had been arriving in the Americas since 1810. On August 25, 1810, a group of Spanish Marines arrived in Veracruz from Cádiz on the frigate, Nuestra señora de Atocha under the command of Rosendo Porlier and accompanying Viceroy Francisco Javier Venegas. These were the first Spaniards to have come from Europe in support of royalists. Frieyro de Lara. Guerra ejército y sociedad en el nacimiento de la España contemporánea. (2009, Universidad de Granada) p. 660. Later, after Mexican independence in 1821, a Spanish garrison was sent from Cuba to occupy Spain's last Mexican outpost, the fortress of San Juan de Ulúa; this force remained there until surrendering in 1825. Finally, a force under Isidro Barradas Valdés attempted to regain control of Mexico in 1829.
