Abstract

Among the worst fates that can befall a nation, and its intelligence services, is to be the victim of a surprise attack. The British response to the European crisis of the 1930s suggests an intriguing paradox. Long-range intelligence predictions were made early in the decade concerning an Anglo-German conflict. Policy in the last years of the 1930s was directed at confronting (or avoiding) the prospect of war with the Third Reich. Defence preparations and strategic planning for much of the 1930s were designed to meet a German threat. When war finally came in September 1939, and the air raid sirens sounded over London, Britain did not suffer an intelligence trauma comparable with the shock dealt out to the Russians by Operation Barbarossa or to the Americans by Pearl Harbour. Yet Britain embarked on World War II manifestly unprepared for a major conflict with Germany.1 The paradox is thus to be found in the condition of a state apparently unsurprised by war, but also unready for it. This essay will attempt to explore the concept of strategic surprise and, through an examination of the origins of intelligence prediction about Nazi Germany, seek to resolve this paradox.
