When the Panzer VI Ausf.E Tiger I tank first arrived on the battlefield, it launched an Allied and Soviet intelligence race to discover everything they could about this new threat. The British Army needed to know how to knock it out, and then communicate their information to the troops that had to face this new German metal monster either by official means or via newspapers. 

Using original official period documents from the Second World War, How to Kill a Tiger Tank: Unpublished Scientific Reports from the Second World War, this is not a typical book on the Tiger tank. It shows 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Unpublished and original documents, discovered in different archives, have been transcribed and reproduced along with existing photographs found in these secret reports. These include top secret Bletchley Park Enigma intercepts of German messages, which were decoded and translated before being sent to Prime Minister Winston Churchill. One such intercept discovered in the archives shows the exact moment when Churchill became aware of the existence of a heavy tank called the Tiger. On 25 November 1942, he marked the intercept in his normal red pen and asked Field Marshal Alan Brooke, Chief of the Imperial General Staff, indicating the word ‘Tiger’ in the message with ‘CIGGS, what are these?’
