The narrative traces more than a century of diplomatic, commercial, and military engagement aimed at establishing regular relations with Tibet, recounting early missions and explorations, treaties negotiated with Chinese authorities, frontier incidents and the eventual 1904 expedition to Lhasa. It examines Tibetan seclusion, Chinese influence, and the practical difficulties of enforcing treaty provisions, then recounts British administrative debates and the mission's conduct and consequences. Concluding chapters analyze causes of policy failure and argue for replacing formal isolation with personal, on-the-spot representation—such as a resident agent—to secure steady neighbourly intercourse.
