During the Napoleonic Wars, the 52nd were part of the Light Division, and were present at most of the major battles of the Peninsula campaign, becoming one of the most celebrated regiments, described by Sir William Napier as "a regiment never surpassed in arms since arms were first borne by men". They had the largest British battalion at Waterloo, 1815, where they formed part of the final charge against Napoleon's Imperial Guard. They were also involved in various campaigns in India.
