Background and detail

Background. British-Tibetan competition for suzerainty over Sikkim fueled the conflict. Tibetan influence waned as Britain established relations with Nepal, Sikkim, and Bhutan. The 9th Chogyal, Thutob Namgyal, looked to the Dalai Lama for spiritual leadership, allowing the Tibetan government to regain political influence. This tension led to fears in Lhasa and Peking that British encroachment through Sikkim would threaten Tibet.

Tension. The 1861 treaty restricted the Chogyal's time in Tibet, but he frequently ignored this provision. In 1887, after residing in Tibet for nearly two years, he declined to meet the Lieutenant-Governor in Darjeeling, citing orders from the Amban in Lhasa. This defiance exacerbated tensions, leading to the postponement of negotiations and the eventual military response.

Military. Tibetan forces crossed the Jelep La pass and occupied Lingtu, showing signs of permanence. The British prepared for a military solution, aiming to expel Tibetans from Lingtu and secure key areas like Gantok and Tumlong. The expedition involved significant military movements and engagements, including the capture of strategic passes and the defense of British positions.
