evidence: During a visit to the central sector of the Indo-Tibet boundary in Uttarakhand, Chief of Defence Staff (CDS) General Anil Chauhan directed Army formations to work for the rehabilitation of the border villages of Nelang and Jadung, near the Line of Actual Control in Chamoli district. [...] After discussing at great length the advisability of pushing forward a post to Tawang, it was decided to go ahead. It was also decided to send troops to Nelang (then written Nilang) and Jadung (then Jadhang), two tiny villages south of the Tsangchok-la, the pass marking the watershed in the area, in the Chamoli district. [...] Already in May 1950, the Ministry of External Affairs had sent a note to the Ministry of Defense asking the latter to comment on the feasibility of walking into the Nilang/Jadhang area. The Ministry of Defense then observed: "The area under dispute is an extremely difficult country physically and climatically, with hardly any communications. It therefore follows that operations in the area will have to be confined to short periods and undertaken by specially trained infantry organized on an ad hoc basis with very scanty artillery support and no support whatsoever from either tanks or aircraft."
