(and points on the "traditional customary boundary" of China declared in 1960). [8] [lower-alpha 1]

The Depsang plains are located in the north-western Aksai Chin. [9] They are bounded on the north by the valley of the Chip Chap River and on the west by the Shyok River. On the east, they are bounded by low hills of the Lak Tsung range, which separate them from the basin of the Karakash River. In the south, the Depsang Plains proper end at the Depsang La pass, but in common parlance, the Depsang region is taken to include the mountainous region to the south of it, including the "Depsang Bulge". The latter is a bulge in theoretical Indian territory, housing the upper course of the Burtsa Nala.

The Karakoram Pass is located to the north of the Depsang Plains, while the Lingzi Thang plains lie to the southeast. On the west is the southern part of the Rimo glacier, the source of the Shyok River. [10]

Francis Younghusband, who travelled here in the late 19th century, described the area as follows: [11]

The Depsang Plains are more than seventeen thousand feet above sea-level, and are of gravel, as bare as a gravel-walk to a suburban villa. Away behind us the snowy peaks of Saser and Nubra appeared above the horizon like the sails of some huge ships; but before us was nothing but gravel plains and great gravel mounds, terribly desolate and depressing. Across these plains blew blinding squalls of snow, and at night, though it was now the middle of summer, there were several degrees of frost.

Line of Actual Control

In 1962, China and India fought a war over the border dispute, following which the Depsang Plains have been divided between the two countries across a Line of Actual Control (LAC), which runs east of the traditional caravan route. Now only the militaries of the two countries inhabit the region, distributed into numerous military camps. The nearest inhabited village is Murgo. [12]

Locations

Burtsa, alternately spelled as Burtse, is a historic halting spot on the caravan route at the southern end of the Depsang Plains, where the Depsang Nala joins the Burtsa Nala. [lower-alpha 2] It currently serves as a military camp of the Indo-Tibetan Border Police (ITBP) and the Indian Army on the Darbuk-Shyok-DBO road, about 15 kilometres on the India's side of the LAC. [13] [14]

North of Burtsa is Qizil Langar, also called Qazi Langar. It lies in a narrow, reddish gorge, immediately to the south of the Depasang La. [15] The Depsang Nala stream flows in the gorge from the west and takes a turn to the south at Qizil Langar. Depsang Nala joins the Burtsa Nala a little to the south of Burtsa and the combined river flows west and drains into the Murgo Nala near the village of Murgo.

Gapshan or Yapshan is a halting place at the confluence of the Chip Chap River and the Shyok River. [16] [17] In the past, on numerous occasions, the Chong Kumdan glacier has blocked the flow of the Shyok River forming a lake called the Gapshan Lake; once the ice dam melts, the lake drains away. [18] [19] [ unreliable source? ] From Gapshan, the Shahi Kangri group of peaks dominate the plains. [20] [17]

At a campground, Polu (or Pulo/Pola) is a traditional temporary shelter built using local mud, four miles north of DBO along the DBO Nala, Maj A. M. Sethi found a memorial stone left by Dr. Ph. C. Visser in 1935. [21]

Tianwendian ("astronomical point") is a border post in the Chinese-controlled territory. It was established after the 1962 war. Before that, another post called Point 5243 served as the main base. From Tianwendian Defence Area, the Chinese have a line of sight extending to Siachen glacier, 140 km away. Closer to the Indian-controlled territory is forward post 5390, a PLA observation point which acts as an extension of Tianwendian. [22] [23] The Tiankong Highway runs parallel to the LAC, connecting Tianwendian and Kongka to the south.

History

Caravan route

Trade routes between Ladakh and Xinjiang Map of Tibet and Pangong Lake in 1873 from Hindutagh-pass-aksai-chin-center2-1873 (cropped).jpg
Trade routes between Ladakh and Xinjiang

The Depsang Plains were regularly traversed by trade caravans, coming via the Karakoram Pass in the north from Yarkand beyond. Filippo de Filippi, who explored the area in 1913–1914, described: [24]

... the caravans come and go incessantly, in the summer, in astonishing numbers. The first one of the season passed on June 28th, coming from Sanju on the Yarkand road; then more and larger ones came; in July there were four in one day, almost all travelling from Central Asia toward Leh—the Ladakhis usually do their trading at home. The caravans were of all sizes, from small groups of 3 or 4 men with 5 or 6 animals to large parties with 40 or more pack-animals; the men on foot or riding asses, the better-to-do merchants on caparisoned horses ...

Filippi also wrote that the experienced caravaners passed through the Depsang Plains without stopping, travelling a distance of 31 miles between Daulat Beg Oldi and Murgo in a single day. [25] Others stopped, either at Qizil Langar to the south of Depsang La, or at Burtsa further south. A stream running from below Depsang La, called Depsang Nala, waters these parts leading to the growth of the burtza plant, which served as fodder as well as fuel for the campers. [26]

The trading caravans declined during the 1940s during tensions in Xinjiang (Chinese Turkestan) and completely stopped in the 1950s. [27] In 1953, the Indian consulate in Kashgar was closed down. The Indian prime minister Jawaharlal Nehru told the Parliament that the Chinese wish to treat Xinjiang as a "closed area". Subsequently, China built the Xinjiang–Tibet highway through Aksai Chin starting the Sino-Indian border dispute, which persists till the present day. [28]

In modern times, the Darbuk–Shyok–DBO Road (DS–DBO Road) has been laid by India along the old caravan route. From south to north, it passes through Sultan Chushku, Murgo, Burtsa and Qizil Langar, to reach Daulat Beg Oldi (DBO).

Exploration

In 1893, Charles Murray, 7th Earl of Dunmore, in his daily records of his travels with Major Roche through Ladakh, Tibet and Pamirs, wrote of seeing musk deer, kiang, Tibetan antelope and a butterfly in the region in and around the Depsang Plains. Dunmore noted that K2, the second highest mountain in the world, could be seen from the plateaus. [29] In 1906, Sven Hedin had travelled east from Burtsa to the Aksai Chin lake on the traditional silk road. [30] The traditional route to Shahidula passed through the plains; Kizil Jilga to Haji Langar to Shahidula. [9]

Flora and fauna

The Depsang Plains are widely observed as forming a high-altitude cold desert without any flora or fauna. [31] Filippo de Filippi, who explored the region in the 1910s, wrote that "the surface of the [Depsang] plateau is a mass of minute detritus, and is entirely devoid of vegetation, except for occasional patches of a yellowish-green plant". [32] A 1985 expedition to the Rimo Glacier found blooming plants at a few places and that "at places [the] plains are marshy and our mules were sinking and we all had to help them out." [33] Burtse ( Artemisia spp. ) plant of the Asteraceae family grows along the Burtsa Nala and Depsang Nala, lending its name to the region. Its leaves were used for fodder and its roots as firewood by caravaners. [34] [35] Potentilla pamirica is also found in the plains. [36]

Small populations of Tibetan antelope (or "chiru"), mountain weasel, Ladakh pika, bharal (blue sheep), Tibetan wolf and woolly hare, among others, can be seen in the plains. [37] According to Brigadier Teg B Kapur, "the [Depsang] plain abounds with wild horses and hares". [38] The populations of chiru are migratory and come to the high-altitude plains for summer grazing. [37] [39] These populations are also the westernmost population of chiru, found at altitudes of up to 5500m. [40] [41] A Schaller Conservation Survey of chiru conducted by the Wildlife Trust of India in 2005 sighted 149 individuals of chiru in 22 groups, all females and kids, in the Depsang area. The southernmost area where chiru were spotted was the Thuksu Doon Doon nullah which flows near the Depsang La. [37] [42] The report says that "Chiru is a mixed feeder and favoured graminoids and forb plant species". [37] In the past, Chiru were killed for their fine wool (called shahtoosh) and many efforts have been taken to protect them in India. [37] [41] [42] Populations of Kiang also move back and forth across the disputed border. [39] In 1990, it was reported that the proposed Daultberg–Depsang Sanctuary would contain the last wild yak, [39] but Schaller Conservation Survey did not locate any in the 2000s. [37]

DRDO-reared double-humped Bactrian camels (originally used along the silk route) will be deployed at DBO and Depsang by the Indian Army for patrolling and transportation. [43] Zanskar ponies are also being used by the Indian Army. [43]

The Republic of China (1912–1949), having faced a revolution in Tibet in 1911, apparently made secret plans to acquire Aksai Chin plateau in order to create a road link between Xinjiang and Tibet. These plans began to get manifested in public maps only towards the end of its rule. [45]

While the Republic of China claims included the Aksai Chin proper, they stopped at the foot of the Karakoram mountains, leaving all the rivers that flow into the Shyok River within India, including the Chip Chap River. (See map.) Communist China also published the "Big Map of the People's Republic of China" in 1956 with a similar boundary, now called the 1956 claim line. [46] [47]

However, in 1960 China advanced its claim line further west, dissecting the Chip Chap River. [47] The Chinese said little by way of justification for this advancement other than to claim that it was their "traditional customary boundary" which was allegedly formed through a "long historical process". They claimed that the line was altered in the recent past only due to "British imperialism". [lower-alpha 5] [48] [49] [50]

Meanwhile, India continued to claim the entire Aksai Chin plateau.

1962 war

India's Intelligence Bureau patrols had come across indications of Chinese activity in the Depsang Plains prior to 1958. [9] However, the Bureau chief B. N. Mullik has stated that "the Chinese did not come into Depsang Plains till October, 1960". [51]

The 1962 Sino-Indian War in the Depsang Plains lasted two days, 20–21 October 1962. The Chinese forces in the area were based at Point 5243 in the present day Tianwendian area. The Indian posts, set up in accordance with India's "forward policy", were manned by the 14th battalion of the Jammu and Kashmir Militia (later Ladakh Scouts), and were mostly of a platoon or a section strength. [52]

The Chinese forces first targeted the post they called "Indian Stronghold No. 6" at "Red Top Hill". They regarded this post specially threatening to their lines of communication. [52] As per the Chinese assessment, the attacking troops had a superiority of 10 to 1 in numbers and 7 to 1 in fire power. The post was eliminated in under two hours, with 42 soldiers killed and 20 captured. [53] Following on this success, the Chinese eliminated 6–7 other Indian posts of a section strength (8–10 troops) and 2 further posts on the second day. [53]

The remaining Indian posts were then given permission to withdraw, as they were not tactically sited and had no mutual support. By 24 October, the withdrawal was completed, with the Indians continuing to hold Saser Brangsa, Murgo, Sultan Chushku and the Galwan estuary on the Shyok River. [53] The Chinese forces advanced to their 1960 claim line in most locations. [53] The one exception was the Burtsa Nala valley to the south of Depsang Plains, where the Chinese eliminated the "bulge" in the Indian territory granted in 1960. This area, called Depsang Bulge, continues to be contested till the present day. [54] [55] [56] [57]

The standoff at the "bottleneck"

India continues to maintain the bulge in the Indian territory as per China's 1960 claim line as Indian territory, while its troops have been asked to patrol up to the ceasefire line marked on Indian maps (which has been referred to as the Patrol Point 10 or PP-10). [58]

In April 2013, the Chinese PLA troops set up a temporary camp at the mouth of Depsang Bulge, where the Raki Nala and Depsang Nala meet, claiming it to be Chinese territory. But, after a three-week standoff, they withdrew as a result of a diplomatic agreement with India. [59] [60] [61] [62] [63] [64] In 2015, China tried setting up a watch tower near Burtsa. [65] [66] Any threat to Depsang affects India's DS-DBO road. [10] Initially India had stationed about 120 tanks in the SSN, and over the years this number has increased. [10]

During the 2020 China–India standoff, the Depsang Bulge was again mentioned as one of the areas where China extended its claims. It came to light that the Chinese troops had been blocking Indian patrols from proceeding along the Raki Nala valley near a location called "bottleneck" since 2017. [67] After a resolution to the standoff at Pangong Lake in February 2021, it was reported that the Chinese started strengthening their positions at Depsang. [68]

The new line being demanded by China amounted to a loss of 250 square kilometres of territory for India, [69] while the loss from India's perception of the Line of Actual Control was 900 square kilometres. [70]

Sub Sector North

The Indian military's Subsector North (SSN) is east of Siachen Glacier, located between the Saser ridge on the southeastern side and the Saltoro Ridge on the Pakistani border. With regards to a two–front war for India, this area can provide for a linkage for Pakistan and China in Ladakh. [44] [71] The territorial wedge created by Depsang Plains–Karakoram Pass–Shyok Valley prevents this territorial linkup. [71]

Notes

  1. The border shown is that marked by the contributors to OpenStreetMap. It may not be fully accurate.
  2. There were actually two campsites called Burtsa Gongma ("upper Burtsa") and Burtsa Yogma ("lower Burtsa"). Only ruined shelters now exist from those sites.
  3. Even though the map is of very low resolution, it is apparent that the Chip Chap River is shown entirely within Ladakh. Qaratagh-su, a stream that flows down from the Qaratagh Pass and joins the Karakash River is shown as the source of Karakash. Karackattu, The Corrosive Compromise (2020, Figure 1) gives more detailed maps showing Samzungling and Galwan river as part of Ladakh.
  4. Map by the US Army Headquarters in 1962. In addition to the two claim lines, the blue line indicates the position in 1959, the purple line that in September 1962 prior to the Sino-Indian War, and the orange line, which largely coincides with the dark brown line, the position the end of the war. The dotted lines bound a 20-km demilitarisation zone proposed by China after the war.
  5. But the military justification for the advancement is not hard to see. The 1956 claim line ran along the watershed dividing the Shyok River basin and the Lingzitang lake basin. It conceded the strategic higher ground of the Karakoram Range to India. The 1960 claim line advanced it to the Karakoram ridge line despite the fact that it did not form a dividing line of watersheds.

<span class="mw-page-title-main">Darbuk–Shyok–DBO Road</span> Border road in India

The Darbuk–Shyok–DBO Road, also called the Sub-Sector North Road, is a strategic all-weather road in eastern Ladakh in India, close to the Line of Actual Control with China. It connects Ladakh's capital city Leh, via the villages of Darbuk and Shyok at southern Shyok River Valley, with the Daulat Beg Oldi (DBO) post near the northern border. The 220-km long section between Shyok and DBO was constructed between 2000 and 2019 by India's Border Roads Organisation (BRO). The DS-DBO Road has reduced the travel time between Leh to DBO from 2 days to 6 hours. In January 2023, BRO announced that it is constructing the DSDBO tunnel on this route.

Sasoma–Sasser La-Saser Brangsa-Gapsam-Daulat Beg Oldi Road 131 km long road through 17,800 feet (5,400 m) high Saser La, and its 18-km-long northwest-to-southeast fork the Sasser Brangsa-Murgo Road, are 30-ft-wide black-topped heavy-military-vehicle-grade motorable road between Nubra Valley and Depsang Plains in Ladakh in India. The sections of SSSG-DBO Road are the 47 km long "Sasoma - Saser La section", 27 km long "Saser La-Saser Brangsa section", 42 km long "Saser Brangsa-Gapsam section" along the upstream of Shyok River which goes northeast of Saser Brangsa, and 10 km long "Gapsam-DBO section". Just after the Saser Brangsa, after crossing the 345 m long bridge over the Shyok River, the SSSG-DBO Road forks into two: 18 km long "Saser Brangsa-Murgo Road" along the downstream of Shyok River which goes southeast of Saser Brangsa, and 52 km long Saser Brangsa-Gapsam-DBO route along the upstream of Shyok River which goes northeast of Saser Brangsa. These forks connect to the Darbuk–Shyok–DBO Road at two places: at Daulat Beg Oldi in northeast and at Murgo in southeast. This strategically important road provides a much shorter alternative access from Nubra Valley to DBO as compared to the longer 230 km route via "DS-DBO Road", reducing the travel time between Nubra valley and DBO from 2 days to mere 6 hours. In September 2023, several sections of the road are already complete, the whole blacktopped route will be completed by October 2024. To provide the all-weather connectivity, the DPR for 7 km long Saser La tunnel under the Saser La till Saser Brangsa was being prepared in June 2023, the tunnel construction will commence in 2025 and will be completed by 2028.

Shyok or Shayok is a village on the bank of the Shyok River in Durbuk tehsil of Leh district in Ladakh, India. It is located at the southern tip of the V-shaped course of the Shyok River, where the Tangtse river joins it from the left. Historically, the winter caravan route from Leh to Yarkand passed through the village. In modern times, India's strategic road to its border post at Daulat Beg Oldi uses the same route.

The Depsang Bulge or Burtsa Bulge is a 900-square-kilometre area of mountain terrain in the disputed Aksai Chin region, which was conceded to India by China in 1960, but has remained under Chinese occupation since the 1962 Sino-Indian War. The area is immediately to the south of the Depsang Plains and encloses the basin of the Burtsa Nala, a stream originating in the Aksai Chin region and flowing west to merge with the Depsang Nala near the village of Burtsa in Ladakh, eventually draining into the Shyok River. The area is perceived to be of strategic importance to both the countries, sandwiched by strategic roads linking border outposts. Since 2013, China has made attempts to push the Line of Actual Control further west into Indian territory, threatening India's strategic road.

<span class="mw-page-title-main">Jeong Nala</span> River in Xinjiang and Ladakh, China and India

The Jeong Nala, also called Jiwan Nala and Nacho Chu, and called Xidagou by China, a tributary of the Shyok River, flows from the disputed Aksai Chin region administered by China to Ladakh in India. It originates at the eastern edge of the Karakoram Range and flows west. It finally confluences in the Indian administered area with the Burtsa Nala on Darbuk–Shyok–DBO Road, and Burtsa Nala itself falls into Shyok River after flowing 7 km south. After the confluence of Jeong Nala with Burtsa Nala, the entire course of river flows along the DSDBO Road to Shyok village.

Gogra (also referred to as Nala Junction) is a pasture and campsite in the Ladakh union territory of India, near the Line of Actual Control with China. It is located in the Kugrang River valley, a branch valley of Chang Chenmo Valley, where the Changlung River flows into Kugrang. During the times of the British Raj, Gogra was a halting spot for travellers to Central Asia via the 'Chang Chenmo route', who proceeded through the Changlung river valley and the Aksai Chin plateau.

Jianan Pass is a mountain pass in the eastern Karakoram Range near the Chang Chenmo Valley. The Line of Actual Control (LAC) between India and China runs through the pass dividing the Indian-administered Ladakh and Chinese-administered Aksai Chin. The pass lies on the watershed between Kugrang and Galwan river basins. The Changlung river basin is also immediately to the east of the pass. While China uses the name "Jianan Daban" for the pass, India refers to it as Patrol Point 15 (PP-15) for border security purposes. The term "Hot Springs" has also been used by Indian media through misapplication of terminology.

    The location and terrain features of this traditional customary boundary line are now described as follows in three sectors, western, middle and eastern. ... The portion between Sinkiang and Ladakh for its entire length runs along the Karakoram Mountain range. Its specific location is as follows: From the Karakoram Pass it runs eastwards along the watershed between the tributaries of the Yarkand River on the one hand and the Shyok River on the other to a point approximately 78° 05' E, 35° 33' N, turns southwestwards and runs along a gully to approximately 78° 01' E, 35° 21' N; where it crosses the Chipchap River. It then turns south-east along the mountain ridge and passes through peak 6,845 (approximately 78° 12' E, 34° 57' N) and peak 6,598 (approximately 78° 13' E, 34° 54' N).

It is clear that there has been reported migration and exchange of individuals towards the western part in its range, but habitat suitability analysis is needed for a better understanding of the reasons for lack of major exchange of individuals between the westernmost (Depsang Plains close to DBO in northern Ladakh and Aksi Chin near Kunlun range) and other populations.

Chiru is a keystone species and world's hardiest mountain ungulates that can survive in temperatures as low as –40C. Most of their distribution range falls above 4,000 m, and in Depsang Plains in northern Ladakh, they can be found as high as 5500 m. [...] The Shahtoosh is banned as chiru are killed for Shahtoosh, from which fine woolen yarn is produced which commands a high price in the market

There is only one interpretation that could make this statement meaningful: this was an implied threat to produce another map claiming additional Indian territory if New Delhi continued in its stubborn refusal to cede Aksai Chin."

[the] traditional customary line, reflected in their map, was formed gradually through a long historical process, mainly by the extent up to which each side had exercised administrative jurisdiction;... Without admitting any inconsistency they also argued that the line of actual control differed from the traditional customary line because of British imperialism and the recent pushing forward of India. These factors apparently could not contribute to the continuous process of change."
