Events on December 9 in history

Patriot forces led by General Antonio José de Sucre defeat a Royalist army in the Battle of Ayacucho, putting an end to the Peruvian War of Independence.

The Battle of Ayacucho (Spanish: Batalla de Ayacucho, IPA: [bataa e aakuto]) was a decisive military encounter during the Peruvian War of Independence. This battle secured the independence of Peru and ensured independence for the rest of South America. In Peru it is considered the end of the Spanish American wars of independence, although the campaign of victor Antonio Jos de Sucre continued through 1825 in Upper Peru and the siege of the fortresses Chilo and Callao eventually ended in 1826.

As of late 1824, Royalists still had control of most of the south of Peru as well as of the Real Felipe fortress in the port of Callao. On 9 December 1824, the Battle of Ayacucho (Battle of La Quinua) took place between Royalist and Independentist forces at Pampa de Ayacucho (or Quinua), a few kilometers from Ayacucho, near the town of Quinua. Independentist forces were led by Simn Bolvar's lieutenant Antonio Jos de Sucre. Viceroy Jos de la Serna was wounded, and after the battle second commander-in-chief Jos de Canterac signed the final capitulation of the Royalist army.

The modern Peruvian Army celebrates the anniversary of this battle.

Antonio José de Sucre y Alcalá (Spanish pronunciation: [anˈtonjo xoˈse ðe ˈsukɾe j alkaˈla] (listen); 3 February 1795 – 4 June 1830), known as the "Gran Mariscal de Ayacucho" (English: "Grand Marshal of Ayacucho"), was a Venezuelan independence leader who served as President of Peru and as the 2nd President of Bolivia. Sucre was one of Simón Bolívar's closest friends, generals and statesmen.

Due to his influence on geopolitical affairs of Latin America, a number of notable localities on the continent now bear Sucre's name. These include the eponymous capital of Bolivia, the Venezuelan state, the department of Colombia and both the old and new airports of Ecuador's capital Quito. Additionally, many schools, streets and districts across the region bear his name as well.
