This 1912 book by Angus Hamilton (1874-1913), a Fellow of the Royal Geographical Society, is an account of the British military expeditions to quell uprisings among remote tribes in north-eastern India in 1911-12. Famous for his earlier books on Afghanistan, the problems of the Middle East, and Somaliland, Hamilton gives a full account of the various phases of the 'Abor expedition' which resulted in a crushing defeat of the local tribes. The book begins with a survey of the geography of the area, and a description of the Abor people, explaining the turbulent background to the murder in March 1911 of two British officials. A highly detailed and illustrated account then follows of the murders, and of the punitive response of the government in Delhi, which sent an expedition both to bring the area back under control and also to carry out geographical surveys of a relatively unknown area.
