In May 1813, as Napoleon launches a desperate bid to save his empire following the disastrous defeat in Russia, the situation in Spain is particularly precarious. French forces have been weakened to make up for the enormous losses in Russia. But Wellington's Anglo-Portuguese army, as well as the Spanish guerrillas, are stronger than ever. Wellington's advance into Spain will liberate Madrid a second time, and conclude with the final showdown of the Peninsular War - the Battle of Vitoria.
