The regiment embarked for India in 1788 for service in the Third Anglo-Mysore War and saw action at the Siege of Bangalore in February 1791 and the Siege of Seringapatam in February 1792. The regiment also saw service in the Second Anglo-Maratha War and fought at the Siege of Aligarh in September 1803. The regiment laid siege to Aligarh Fort, a fort commanded by a French mercenary officer Pierre Perron and captured it from the Marathas. The French prepared for the siege by lining 14 ditches around the fort with sword-blades and poisoned chevaux-de-frise. The walls were reinforced with French artillery, and the French also used tigers and lions of Scindia's menagerie. During the battle, the British lost as many as 900 soldiers. The regiment went on to fight at the Battle of Delhi in September 1803, the Battle of Laswari in November 1803, and the Battle of Deeg in November 1804. For their distinguished service in these actions, King George III authorized the regiment to have the word "Hindoostan" emblazoned upon the regimental colours, along with an elephant badge with a howdah atop the elephant, also inscribed with the word "Hindoostan". The regiment returned to England and became the 76th (Hindoostan) Regiment of Foot in October 1806.
