The Rajah of Nepaul having broken the terms of treaty made by him with the Honorable East India Company, the battalion marched for his territories on the 15th of January 1816, and arrived at Bullvee Camp on the 24th, where it joined the army under the command of Major-General Sir David Ochterlony, K.C.B., who commanded the forces assembled on the frontiers of Nepaul; on the 3rd of February the brigades advanced by their respective routes into Nepaul, Sir David Ochterlony remaining in company with the third and fourth brigades (to the former of which the EIGHTY-SEVENTH belonged), and marched through the forest at the foot of the Nepaul Hills on the 9th. The light company of the battalion with those of the native infantry of the brigade with two guns under the command of Lieut. John Fenton, formed the advanced guard, and had a very arduous duty to perform, in carrying the guns through the forest, which was accomplished by the personal exertions of each individual. On the 10th, the third brigade arrived at Semul Cassa Pass, and at nine o’clock A. M. the light company of the EIGHTY-SEVENTH, commanded by Lieutenant Fenton, accompanied by Sir David Ochterlony, was drawn up the pass, a height of thirty feet, by the officers’ sashes, the brigade then about five miles from the pass; on the 19th it reached the village of Etoundah on the banks of the Rapti. The advanced guard again exerted themselves in opening a communication between the third and fourth brigades through the Cheria Ghanty Pass.
