Guerra de los Mil Días
The Battle of Bucaramanga () was a battle in the Santander Campaign of the Thousand Days' War in Colombia. It took place between 11 and 13 November 1899. After an earlier defeat in a naval engagement on the Magdalena River, the Liberal rebels skirmished with the Conservative government around Piedecuesta in late October. The Conservative forces under General Juan B. Tovar conducted a fighting retreat to Bucaramanga.
