Sieges of Tarifa, Ciudad Rodrigo 1812 and Valencia

The siege of Tarifa of 20 December 1811-5 January 1812 was an unsuccessful French attempt to capture one of the few remaining Spanish-held strongholds in Andalusia.
The siege of Ciudad Rodrigo of 8-19 January 1812 was a major success for Wellington’s British and Portuguese army, and marked a significant turning point in the Peninsular War - the moment when the French lost the initiative in Spain
The combat of Navas de Membrillo of 29 December 1811 was a minor clash between a British and Portuguese expedition under General Hill and part of the French garrison of Estremadura.
The siege of Valencia of 25 December 1811-9 January 1812 was the final major French success during the Peninsular War, and saw French power in eastern Spain reach its maximum extent.
The French invasion of Valencia of September 1811-January 1812 was the last major French success during the Peninsular War, and saw them virtually complete the conquest of eastern Spain, but at the same time they were forced to weaken their forces on the Portuguese border, allowing Wellington to begin the campaign that led to Salamanca, and the beginning of the end for the French in Spain.
