adviser near Thủ Dầu Một, in an incident that constitutes the only known evidence of direct Soviet involvement in the 1945–1946 war. He was handed over to Lieutenant-Colonel Cyril Jarvis, commander of the 1/1 Gurkha Rifles. 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). From there he disappeared from the annals of history. From September 1945 the 7th Indian Infantry Division, which the 4th Battalion was part of, was deployed to Siam (now Thailand) as part of an occupation force sent there to disarm the large Japanese forces present. The Battalion subsequently moved to Malaya in 1946 and then onto India. In 1946, the 2nd Battalion, having been captured in Malaya in 1942, was reconstituted from personnel taken from the 3rd Battalion, which subsequently was demobilised along with the 4th and 5th Battalions. Post Independence In 1947 an agreement, known as the Tripartite Agreement between India, Nepal and the United Kingdom was negotiated in order to determine what would happen to the Gurkhas upon the formalisation of India's Independence. As a result of this agreement it was decided that of the pre-war Gurkha regiments, four would be transferred to the British Army, while six—one of which was the 1st Gurkhas—would become part of the newly independent Indian Army. Despite India achieving its independence, the regiment retained its full designation until 1950 when it became the 1st Gorkha Rifles (The Malaun Regiment), also adopting the Indian spelling of Gurkha, following India's transition to a republic. Over time the wartime battalions that had been disbanded in 1946 were re-raised, so that by 1965 the Regiment consisted of five battalions once more. 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. 6th Battalion On 1 April 2015, a new battalion with about 700 soldiers was raised as the 6th Battalion, 1st Gorkha Rifles (6/1GR); it was the first time in 50 years that a new Gorkha battalion had been formed. 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. It is the first Gorkha battalion comprising only locally
