It lies on a spur of the Karakoram range that intrudes into the Chang Chenmo Valley adjacent to the disputed Aksai Chin region.
[3] In the Ladakhi language, Kongka (Tibetan: གོང་ཀ, Wylie: gong ka) means a "low pass or ridge, high point or rise of a plateau".
(Map 3) In the Indian-controlled territory immediately to the west of Kongka Pass lie the notable Hot Springs (at a location called Kyam).
On a tributary of Silung Kongma called Nyingri lies the route to the Pangong Lake region, via Kyungang La,[c] which was once regarded as the boundary between Ladakh and Tibet.
[11] Colonial-era British sources state that the traditional boundary between Ladakh and Tibet, accepted by both sides, was at Lanak La, where the Changchenmo River originates.
While maintaining this position, the Chinese would lay the Sianking–Tibet road (now G219) through Aksai Chin to Indian objections and even imprison a two-men strong patrol party.
The party was led by an Intelligence Bureau officer of the rank of Deputy Superintendent, Karam Singh, who was an experienced patroller in Ladakh.
Singh states that they had established a post at Hot Springs and were about to head to Shamal Lungpa when, on 20 October, two men sent out for reconnaissance went missing.
[26] The same evening, Singh dispatched a 10-men-strong party to investigate the disappearance, who returned late night and reported extensive hoof-marks in the region suggesting the presence of Chinese cavalry.
[17] On the morning of 21 October, a forward search party of 20 men set out on ponies under Singh; the rest was ordered to follow on foot under another commander called Tyagi.
[17] After release, Karam Singh reported that the detained personnel were put in a storage pit for four days under severe climatic conditions without water, refused medical attention, interrogated in 12 hour stretches for further several days, induced to sign false confessions about them being responsible for the episode, window-dressed for photographs, and finally returned to India on 14 November.
[32][17] The bodies of the dead soldiers were returned a day earlier at the new border of Kongka Pass and China rejected payment of any compensation.
[17] Scholar John Rowland states that, through these means, China obtained the "evidence" it needed to claim that it was India that broke the Panchsheel (peace agreement between the two countries) unprovoked.
[f] Indian Army castigated the Intelligence Bureau for causing mindless provocations at the frontiers without bringing them in confidence and from 1 November, took charge of manning all border-posts in the sector.
