PLOT
In 1812 French forces in Spain were severely overstretched, as Napoleon withdrew the best troops for his invasion of Russia. Wellington saw an opportunity to strike. First he secured the strategic fortress-cities of Ciudad Rodrigo and Badajoz, both taken in bloody assaults, then advanced to Salamanca, where his Anglo-Portuguese army met Marshal Marmont's French army in one of the most decisive clashes of the Peninsular War.
