In this definitive account of the Peninsular War (1808-14), Napoleon's six-year war against Spain, Ronald Fraser examines what led to the emperor's devastating defeat against the popular opposition - the guerrillas - and their British and Portuguese allies. As well as relating the histories of the great political and military figures of the war, Fraser brings to life the anonymous masses - the artisans, peasants and women who fought, suffered and died - and restores their role in this barbaric war to its rightful place while overturning the view that this was a straightforward military campaign. This vivid, meticulously researched book offers a distinct and profound vision of 'Napoleon's Vietnam' and shows the reality of the disasters of war: the suffering, discontents and social upheaval that accompanied the fighting. With a new Introduction by Perry Anderson.
