Apart from that invasion of Tibet, he travelled extensively and kept notes obsessively. In later life he developed an "unhealthy" interest in Eastern philosophy. He ended as a mystic with a penchant for advocating Asian self-rule at the most inappropriate of imperial forums.
Like other players in the Great Game, he spent much time in Kashmir. He used the Valley as a base for expeditions beyond the mountains. His wide-ranging interests gave him an understanding of local mores absent in more buttoned-down gora log. This monograph was one of those quaint collaborations that the Raj produced. The text is studded with the paintings of Major E. Molyneux. Younghusband produced a comprehensive catalogue of the history, geography, ethnicity, hunting prospects ("sport"), administration and land reform of the Valley.
