In 1814 the corps was again called upon to take the field against the Ghoorkas of Nepaul, a squadron being attached to the division commanded by Major-General Sir Robert Rollo Gillespie, on whom devolved the task of forcing a passage into the Deyrah Dhoon. The troops entered the pass on the 25th of October, and commenced the siege of Kalonga, a fort on the top of a steep hill near Deyrah. On the 31st of October, an attack was made by storm, but failed; when, in the absence of any other reserve, the squadron of the 8th was dismounted, and, headed by General Gillespie himself, was led to the attack of the fort. They penetrated through the first stockade, cleaving their way through the dense masses of the enemy with their sabres, and a few actually got into the fort, but for want of further support were finally repulsed. General Gillespie himself was killed, and all the officers, four sergeants, and fifty-one men being wounded out of the squadron of one hundred sabres. After this, the fort was besieged in form, and held out gallantly for a month, but was then evacuated by the Ghoorkas. The regiment next assembled at Saharunpoor, and formed part of the Army of Observation near Delhi, to overawe the Mahratta Chiefs, during the rest of the Nepaul war. Early in 1817, the 8th was present at the siege of Hattrass, and returned to Meerut. In October of the same year, the corps again took the field, under Major-General Donkin, against the Pindarees. After forced marches for several days, they came up with the enemy, and totally routed them. In 1820, the 8th marched to Cawnpore, relieving the 11th Light Dragoons (now the 11th Prince Albert's Own Hussars), and remained at this station until 1822, when, after an absence of twenty-seven years from Europe, twenty of which it passed under the burning suns of India, the regiment returned to England. His Excellency the Governor-General issued the following order, on the embarkation of the regiment:-- "Fort William, December 6, 1822.
