Goana după submarinele naziste: The Wrens

SINOPSIS

When Gilbert Roberts arrives to set up his proposed Western Approaches Tactical Unit (WATU) for U-Boat wargaming, he receives a decidedly frosty reception from Admiral Sir Percy Noble who is convinced the Allies already possess the tactics and expertise to defeat the Kriegsmarine. Nevertheless, Roberts presses on and, enlisting the help of Jean Laidlaw and a small team of WRENS, based in Liverpool, begins the process of round-the-clock wargaming to devise tactics to outmanoeuvre the U-Boat attack formations.
