Sanju Pass

During ancient times, it was the last on a series of difficult passes on the most common summer caravan route between Ladakh and the Tarim Basin.

From there in summer the caravans normally headed north across the Sanju Pass to modern Guma (Pishan) in the Tarim Basin and then either northwest to Karghalik and Yarkand or northeast to Khotan.

Travellers were also often prevented from accessing it for considerable periods during hot weather due to flooding of the Toghra about 9 miles (14 km) below Shahidula.

In attempt to assert control to the Kunlun Mountains, the Maharajah of Kashmir constructed a fort at Shahidulla, and had troops stationed there for some years to protect caravans.

[7] There is evidence that the Chinese had mined jade in the region at least as early as the Later Han Dynasty and up until the quarries were abandoned during the Muslim Rebellion in 1863–4, just prior to Mr. Johnson's trip in 1865.

The Kashmiri and Yarkandi outposts were only two stages apart on either side of the Karakash river..."[10] to the northwest of the Hindutash in the north eastern frontier region of Kashmir.

[citation needed] Although the Maharajah of Kashmir apparently indicated a wish to reoccupy the fort at Shahidulla in 1885, he was prevented from doing so by the British and so the territory remained under effective Chinese control.
