At Vitoria, Spain, a massive allied British, Portuguese and Spanish force under British General Arthur Wellesley routs the French, pushing them out of Spain in the decisive battle of the Peninsular War.
On February 16, 1808, under the pretext of sending reinforcements to the French army occupying Portugal, French Emperor Napoleon Bonaparte invaded Spain. Thus began the Peninsular War, an important phase of the Napoleonic Wars that was fought between France and much of Europe between 1792 and 1815. During the first few weeks after their 1808 invasion of Spain, French forces captured Pamplona and Barcelona and on March 19 forced King Charles IV of Spain to abdicate. Four days later, the French entered Madrid under Joachim Murat. In early May, Madrid revolted, and on June 15 Napoleon’s brother, Joseph, was proclaimed the new king of Spain, leading to a general anti-French revolt across the Iberian Peninsula.
