Enigma and the Intelligence War

Overview

The Enigma cipher was the backbone of German military, air and naval intelligence communications during World War II. Bletchley Park was home to the Allied codebreakers who worked in impenetrable secrecy on decryption of the cipher and, in the process, gave birth to the modern world of computing. Bletchley was acquired in 1938 by the Government Code and Cypher School and, at its wartime peak, some nine thousand men and women worked there.

This course, which includes a full-day site visit to Bletchley Park, will analyse the development of decryption measures, and consider both the impact of Bletchley’s work on the war in Europe and the Far East and the extent to which it may have shortened the war and ensured an Allied victory.  

This course is part of The Oxford Experience summer school, held at Christ Church.

Seminars and field trip

Monday seminars

We begin with a review of the pre-war intelligence heritage of the ‘Station X’ operation, including the invaluable work of Polish intelligence in the 1930s, and its establishment at the Bletchley Park country house complex. The commercial origins and functional structure of the Enigma substitution codes will be examined as will the period’s unique social and political circumstances.

Tuesday seminars

Y Stations: these were the vital listening stations that gathered the signals intelligence material essential to Bletchley Park’s secret work. We will also consider the key personalities – not only Alan Turing – whose painstaking and insightful work led cryptographic success, the risks inherent in that very success, as well as the technical advances that emerged from it.   

Wednesday seminars

Today we will evaluate the Enigma decrypts in relation to particular wartime theatres and campaigns, not least the vital Battle of the Atlantic on whose successful outcome not only the sustenance of the British nation depended, but also the Allies’ eventual capacity to take the war to the enemy and reconquer Europe.

Thursday seminars

Full day visit to Bletchley Park, Buckinghamshire, which has been a museum since 1993. Participants will visit the original Mansion, the Bombe and Codebreaking Huts and the Museum which includes Enigma machines. The adjacent National Museum of Computing will also be visited.

Friday seminars

The concluding day considers the work of Station X as extended to overseas outstations and operational theatres. There will be an informed conjectural discussion of the progress and conduct of World War II had Ultra Intelligence not played such a crucial role. Finally, there will be a critical evaluation of recent cinematic depictions of the Station X operation.
