The Battle of Nalapani was the first battle of the Anglo-Nepalese War of 1814–1816, fought between the forces of the British East India Company and Nepal, then ruled by the House of Gorkha. The battle took place around the Nalapani fort, near Dehradun, which was placed under siege by the British between 31 October and 30 November 1814. The fort's garrison was commanded by Captain Balbhadra Kunwar, while Major-General Robert Rollo Gillespie, who had previously fought in the Battle of Java, was in charge of the attacking British troops. Gillespie was killed on the first day of the siege while rallying his men. Despite considerable odds, both in terms of numbers and firepower, Balbhadra and his 600-strong garrison successfully held out against more than 5,000 British troops for over a month.
After two costly and unsuccessful attempts to seize the fort by direct attack, the British changed their approach and sought to force the garrison to surrender by cutting off the fort's external water supply. Having suffered three days of thirst, on the last day of the siege, Balbhadra, refusing to surrender, led the 70 surviving members of the garrison in a charge against the besieging force. Fighting their way out of the fort, the survivors escaped into the nearby hills. Considering the time, effort, and resources spent to capture the small fort, it was a pyrrhic victory for the British. A number of later engagements, including one at Jaithak, unfolded in a similar way; but more than any other battle of the war, the fighting around Nalapani established the Gurkhas' reputation as warriors. As a result, they were later recruited by the British to serve in their army.
Background
Situation
In 1814 under the new and ambitious Governor-General Francis Edward Rawdon-Hastings, the Earl of Moira, the long-standing diplomatic disputes between British India and the Kingdom of Nepal, caused by expansionist policies of both parties, descended into open hostility. The British East India Company sought to invade Nepal not just to secure the border and to force the Nepali government to open trading routes to Tibet, but also for what Hastings saw as a geo-political necessity to secure the foothold of the Company in the Indian sub-continent.
The initial British campaign plan was to attack on two fronts across a frontier stretching more than 1,500 km (930 miles), from the Sutlej river in the west to the tista river in the east. On the eastern front, Major-Generals Bennet Marley and John Sullivan Wood led their respective columns across the Tarai towards the heart of the Kathmandu Valley; at the same time Major-General Rollo Gillespie and Colonel David Ochterlony led the columns on the western front. These two western columns faced the Nepalese army under the command of Amar Singh Thapa. Around the beginning of October 1814, the British troops began to move towards their depots and the army was soon after formed into four divisions: one at Benares, one at Meerut, one at Dinapur, and one at Ludhiana.
The division at Meerut was formed under Gillespie, and originally consisted of one British infantry regiment, the 53rd, which with artillery and a few dismounted dragoons, made up about 1,000 Europeans. In addition to this, there were about 2,500 native infantrymen; this made up a total force of 3,513 men. Once assembled, it marched directly to Dehra Dun, which was the principal town in the Dun Valley. After having captured or destroyed the forts in the valley, the plan called for Gillespie to either move eastwards to expel Amar Singh Thapa's troops from Srinagar, or westwards to take Nahan, the largest town in the Sirmaur district, where Amar Singh's son, Ranjore Singh Thapa, controlled the government. Once completed, Gillespie was to sweep on towards the Sutlej in order to isolate Amar Singh, and force him to negotiate.
