Matt Hefler Presents: On This Day November 21, 1940

On this day (November 21st) in 1940: A German bomber attacks the area around Bletchley Park, home of the main operations of the British Government Code & Cipher School (GC&CS). The GC&CS was the UK Signals Intelligence Agency, the forerunner of the Government Communications Headquarters (GCHQ) and the organizations credited with cracking the German ENIGMA enciphering system. Though facilities at Bletchley Park were damaged, it seems clear the Germans had little idea of the significance of the target. Learn more about Bletchley Park here:
