Tibet Frontier Commission
The Tibet Frontier Commission headed the British expedition to Tibet in 1903–04. The Commission comprised seven diplomats and army officers, led by Colonel Francis Younghusband. Despatched on the orders of Lord Curzon, Viceroy of India, the Commission was intended to establish diplomatic relations with the government of Tibet and, in particular, to resolve the dispute over the border between Tibet and British-held Sikkim. The Commission was escorted by a large military force led by Brigadier-General J. R. L. Macdonald. However, the expedition was met with hostility by a Tibetan government uninterested in negotiation, and conflicts erupted, in one instance resulting in the massacre of hundreds of poorly armed and poorly trained Tibetan soldiers, which were no match for a professional army equipped with Maxim machine guns.
Captain Herbert James Walton served as Medical Officer and Naturalist to the Commission, and was able to make a comprehensive study of the flora and fauna of the southern and central areas of Tibet during the expedition's slow progress to the capital, Lhasa.
