According to Wikipedia: "General Sir John Miller Adye GCB (1 November 1819 – 26 August 1900) was a British general and amateur artist." According to the Preface: "The subject of our policy on the North-West frontier of India is one of great importance, as affecting the general welfare of our Eastern Empire, and is specially interesting at the present time, when military operations on a considerable scale are being conducted against a combination of the independent tribes along the frontier. It must be understood that the present condition of affairs is no mere sudden outbreak on the part of our turbulent neighbours. Its causes lie far deeper, and are the consequences of events in bygone years."
