At the beginning of the Napoleonic period, the British Army's record left something to be desired. During the Peninsular War (1808-1814), however, Wellington led and trained an army that never knew a major defeat on the field. Even Wellington himself described his army as able to go anywhere or do anything. This book examines the formidable British Army which played an integral part in stalling Napoleon's advance, focusing on the staff, infantry, cavalry, artillery and sieges and sappers. Numerous illustrations, including eight color plates, vividly depict the weaponry and uniforms of Wellington's Peninsular Army.
