The Gurkha War was fought between the Gorkha kings of Nepal and the British East India Company as a result of border tensions and ambitious expansionism especially into Kumaon, Garhwal and Kangra hills.

[3][4] As a result, during the post war settlement a clause was inserted into the Treaty of Sugauli enabling the British to recruit Gorkhas.

[4] On 24 April 1815, at Subathu, the East India Company formed a regiment with the survivors of Thapa's army calling it the First Nusseree Battalion.

The following year Lieutenant John Adam Tytler became the first Gurkha officer to be awarded the Victoria Cross (VC), receiving it for his actions against rebels at Choorpoorah.

In 1875, the regiment, under the command of Colonel James Sebastian Rawlins, was sent abroad for the first time, when it took part in the effort to quell a rebellion in Malaya during the Perak War.

[6] This title had been adopted to commemorate due to the significance of Malaun to the Regiment; it was where the British had decisively beaten the Gurkhas in 1815 during the Anglo–Gurka War and subsequently recruited them into the Nusseree battalions.

In December, the 1st Battalion was deployed to the Western Front in France as part of the Sirhind Indian Infantry Brigade, attached to 3rd (Lahore) Division.

[12] Conditions on the Western Front were very different to those that the regiment had been used to in the sub-continent and they, along with the rest of the Indian Army troops deployed, suffered badly during the winter months.

In 1916, the 1st Gurkhas took part in a number of attempts, including the attack on Dujaila Redoubt in March, to relieve Kut-al-Amara, which had been besieged by the Ottomans since 7 December 1915.

In Burma, a similar situation occurred, the Allies—having come under intense attacks from the Japanese who had begun their offensive in December—had to commence a retreat to India from February 1942 which was completed in May.

[20] Later, the battalions of the Regiment saw heavy fighting again in 1944 in the Arakan campaign and during the Japanese offensive against north-east India where two important battles, Kohima and Imphal, took place from March to June 1944.

The Regiment subsequently took part in the successful Allied offensive into Burma and on 3 May 1945 the Burmese capital Rangoon was liberated by British forces.

[22] The war concluded with the formal surrender of Japan on 2 September 1945 on the deck of the USS Missouri in Tokyo Bay; the Allies had prevailed after nearly six years of fighting.

The operations against the Viet Minh gradually became more intense and after substantial French reinforcements arrived the British and Indian forces departed by May 1946, and the First Indochina War would begin shortly afterwards.

[citation needed] On 25 October, a Japanese patrol captured a Russian adviser near Thủ Dầu Một, in an incident that constitutes the only known evidence of direct Soviet involvement in the 1945–1946 war.

Jarvis made several attempts at interrogation, but it was fruitless, so the intruder was handed over to the Sûreté, the French criminal investigation department (equivalent to the CID).

[3][Note 3] In 1961, Captain Gurbachan Singh Salaria received the posthumous Param Vir Chakra (PVC), India's highest military honour, for his actions in the Congo when the 3rd Battalion, of which he was part, was on United Nations service.

The new battalion, christened "Kanchi Paltan", was raised at Sabathu in the Shivalik foothills near Shimla, which is the location of the 14 Gorkha Training Centre.
