Sieges of Tortosa and Tarragona, 1810-11

The siege of Tortosa of 16 December 1810-2 January 1811 was the first of three successful French attacks on Spanish-held cities that briefly appeared to give the French control of eastern Spain.
The siege of Tarragona of 3 May-28 June 1811 was the second of three sieges that saw the French seize the last major cities in Spanish hands in the east of the country in a twelve month period, an achievement that seemed like it might given them a chance to finally secure their control of the area
