UK, Edinburgh - The National Museum of Scotland is considering an exhibition to mark the centenary of the 23rd Sikh Pioneers expedition to Tibet.

Historian and writer Mike Turnbull has been pressing for years for an exhibition of the artefacts which his grandfather, Bruce Turnbull, and other soldiers brought back from their year-long journey and were donated to the museum. Grandpa Turnbull was an officer in the regiment that took part in the Sir Francis Younghusband expedition to Tibet in 1903-04.

Hundreds of men escorted Younghusband, the British commissioner to Tibet, on a secret journey through the Himalayas with the apparent objective of striking a trade deal, but the underlying agenda was to maintain the British Empire's dominance in the area.
