Chilean War of Independence: Chilean forces captured the city of Valdivia.

The Chilean War of Independence was a military and political event that allowed the emancipation of Chile from the Spanish Monarchy, ending the colonial period and initiating the formation of an independent republic.

The Capture of Valdivia was a battle in the Chilean War of Independence between Royalist forces commanded by Colonel Manuel Montoya and Fausto del Hoyo and the Patriot forces under the command of Thomas Cochrane and Jorge Beauchef, held on 3 and 4 February 1820. The battle was fought over the control of the city Valdivia and its strategic and heavily fortified harbour. In the battle Patriots gained control of the southwestern part of the Valdivian Fort System after an audacious assault aided by deception and the darkness of the night. The following day the demoralised Spanish evacuated the remaining forts, looted local Patriot property in Valdivia and withdrew to Osorno and Chiloé. Thereafter, Patriot mobs looted the property of local Royalists until the Patriot army arrived to the city restoring order.
