The Battle of Uchumayo occurred in the first days of February 1836, on the outskirts of Arequipa, Peru. It was the most important confrontation in the series of skirmishes, prior to the Battle of Socabaya, that the forces of the United Army under the command of Santa Cruz held with the restaurateurs under the command of Salaverry.
After hastily abandoning the city in the face of the hostility of its inhabitants and the advance of Santa Cruz, Salaverry retired to the vicinity of the town of Uchumayo where at the entrance to the bridge he had a series of parapets and trenches built in which he placed 2 pieces of artillery. protected by a considerable force of infantry.
