Featured battle : Daiuraadha, The Year of the Airplane

Part of Operations against the "Mad Mullah"

Date : 01 November 1919 - 01 April 1920

The final campaign, against Mohamed bin Abdullah Hassan (The Mad Mullah) and his Dervishes, was mounted in great secrecy, taking place in the early months of 1920. This first campaign in which the Royal Air Force took a major part was a truly tri-service effort. Lasting just over three weeks it resulted in the eviction of the Mullah from the Somaliland Protectorate and the disintegration of his Dervish following.

The Decline of Empires in South Asia

Heather A Campbell
This book covers quite a niche subject in the history of what became known as "The Great Game" between the British Empire and the Russian Empire in South Asia. It focuses on the problems of imperial control over primarily Afghanistan in the years 1919-1923, and how the conflicts between the Indian government, the India Office, and the Foreign Office in London. It uses as a comparison the approaches taken during those same years in Persia, and while it covers a number of viewpoints, it largely revolves around Lord Curzon, his strong personality, and the mistakes it argues that he made because of it.
I found this book to be fascinating, and extremely thoroughly researched (the notes pages and bibliography are approximately one third of the book) but it is really quite academic and probably not for a casual reader.
