I suspect this may well be the key air power text to come out this year. It is, Bombing the People: Giulio Douhet and the Foundations of Air Power Strategy, 1884–1939 by Thomas Hippler and it is due to be published by Cambridge University Press later this year. Guilio Douhet is one of the triumvirate of inter-war air power thinkers whose ideas still reverberate to this day. The others are Major-General William ‘Billy’ Mitchell and Marshal of the Royal Air Force Viscount Trenchard; though the latter was not so much of theorist but a pragmatist. With the exception of a few scholarly articles there has been little real analysis of Douhet’s thinking on air power and its strategic role. Hopefully, this book will fill that gap. The is no blurb on the Cambridge University Press website for it yet but this short description appears on Amazon:
Giulio Douhet was one of the world’s most important early air power strategists. This book offers the first comprehensive interpretation of Douhet’s strategic thinking and its broader context. It charts the development of the strategy of targeting civilian populations from colonial warfare to the wake of World War II.
I do hope it lives up to its billing!
