The 1807-14 war in the Iberian Peninsula was one of the most significant and influential campaigns of the Napoleonic Wars. Arising from Napoleon's strategic need to impose his rule over Portugal and Spain, it evolved into a constant drain on his resources. Sir Charles Oman's seven-volume history of the campaign is an unrivalled and essential work. His extensive use and analysis of French, Spanish, Portuguese and British participants' accounts and archival material, together with his own inspection of the battlefields, provides a comprehensive and balanced account of this most important episode in Napoleonic military history. The fate of the Iberian Peninsula was very much in the balance during the period January-September 1809, when it seemed all too possible that Napoleon would achieve control over Spain and Portugal. But, as this volume shows, Spanish resistance to French occupation continued, and the return of Sir Arthur Wellesley (later Duke of Wellington) to the Peninsula signalled the start of a number of victories, including the outmanoeuvring of the French at Oporto and culminating in the hard fought battle of Talavera.
