12. 51st Regiment of Foot (Light Infantry)
The 51st Regiment of Foot, known as the King’s Own Yorkshire Light Infantry, was converted to a light infantry role in 1809, emphasizing skirmishing and reconnaissance. Under Wellington’s command, they played a pivotal role in the Peninsular War, participating in key battles such as Fuentes de Oñoro, Salamanca, and Vitoria. Their adaptability and effectiveness in light infantry tactics significantly contributed to the success of British forces during the conflict (napoleon.org).
