When the Panzer VI Ausf. E Tiger I tank first arrived on the battlefield, it started the Allied and Soviet intelligence race to discover everything they could about this new threat. The British Army quickly needed to know how to knock it out, then communicate that information back to the troops that had to face this new German metal monster either by official means or via newspapers. This is not a typical book on the Tiger tank. It tries to show the reader what the British and Commonwealth forces knew about the Tiger I tank during the war and the results of scientific firing trials. Unpublished Second World War original documents, discovered in different archives, have been transcribed and reproduced along with any existing photographs found in those official secret reports. These include top-secret Bletchley Park and Enigma intercepts of German messages that were decoded and translated before being sent to wartime Prime Minister Winston Churchill. Illustrated with over 360 images, "How to Kill a Tiger Tank" is the definitive examination of a world-changing fighting vehicle.
