The Battle of Benavente (29 December 1808) was a cavalry clash in which the British cavalry of Lord Paget defeated the elite Chasseurs à cheval (Mounted Chasseurs of the Imperial Guard) during the Corunna Campaign of the Peninsular War. The French chasseurs were broken and forced into the River Esla; their commanding officer, General Lefebvre-Desnouettes, was captured. The action was the first major incident in the British army's harrowing retreat to the coast and ultimate evacuation by sea.
