A great story I did not know. Some of the Wrens were only seventeen.


Wargaming the Atlantic War: Captain Gilbert Roberts and the Wrens of the Western Approaches Tactical Unit:

The Western Approaches Tactical Unit (WATU) was a Royal Navy analysis team founded in early 1942. Their remit was to study the conduct of convoy operations, to understand how the U-boats operated and to formulate tactics to counter this evolving threat. The unit was made up of experienced naval officers and a number of talented young women from the WRNS. Using conceptual/analytical wargames, WATU developed a range of tactics during the war and disseminated these to over 5,000 Allied officers through a series of lectures and tactical games. Many of these appeared in the Atlantic Convoy Instructions and were used with considerable success by Allied naval forces during the decisive engagements of the Atlantic War. The essay outlines the origins and purpose of the organisation, how the team functioned, the individuals that conducted the wargames, and the series of evolving challenges that it was intended to overcome – focusing on the series of Anti-Submarine Warfare training and analysis wargames conducted by the unit between 1942 and 1943. The article concludes with an overview of some of the numerous lessons that modern defence analysts could draw from the work of the unit and highlights its utility as an exemplar of the use of wargaming as a tool for modern defence analysis.
