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. Of the four British divisions mentioned above, Gillespie's was the first to penetrate the enemy's frontier. The Nepalese had anticipated that Dehra Dun would be the first place of assault, and had tasked Captain Balbhadra Kunwar with the fortification of the place. When Balbhadra Kunwar, commander of the Nepalese defence army at Dehradun, heard of the approach of the British Army and its size, he realised that it would be impossible to defend the city. He withdrew from Dehradun and moved his force of about 600, On 22 October, before the British declaration of war on 1 November 1814, Gillespie seized the Keree Pass leading into the Dun Valley. He then proceeded to Dehra unchallenged. Nevertheless, he responded by sending his "salaam" to the English "sirdar", assuring him that he would soon visit him in his camp. Every point where the fort was approachable, or thought weak by its defenders, was bolstered by
stockades made out of stones and stakes that had been stuck into the ground. These were covered by cannons that were placed where they could be most effective, and a
wicket gate that flanked a large part of the wall, was left open but cross-barred, to make it difficult for attacking soldiers to enter but also to channel their advance towards a cannon that had been placed at the gate to
enfilade its approach with showers of
grapeshot. == Battle ==
