Government and Armed Forces in Britain, 1856-1990 [PDF ebook] 

In a period that began with Britain controlling a world-wide empire and included two world wars, followed by the Cold War and massive expenditure on nuclear armaments, the relationship between the politicians and the generals has been central to British history. While it is correctly assumed that the Armed Forces have never threatened British political stability in modern times, the relationship between the military and their political masters is a major, if under-emphasised, theme of British history. While in theory the politicians decided strategy and the military implemented it, in practice decisions often depended on the personalities and experience of those involved. Asquith, the epitome of the civilian, left major strategic decisions in the hands of the military; while Churchill, an ex-soldier and ex-First Lord of the Admiralty, rode roughshod over professional military advice. In a period when arms before ever more technologically sophisticated, there was also the problem of how far politicians could decide on strategies proposed by the military other than by the crude yardstick of cost. The essays in
Government and the Armed Forces in Britain, 1856-1990 provide a coherent account not only of the major decision-making of warfare but also of the changes in the organisation and control of the Armed Forces.
