During the search of the apartment, it was found that Wenzel had left a series of coded messages and two messages written in German that were waiting to be enciphered. These messages contained details of such startling content, the plans for Case Blue, that Piepe immediately drove to Berlin from Brussels and, after revealing his find and explaining its relevance, met with Wilhelm Canaris. Canaris arranged an immediate meeting with Wilhelm Keitel who was Chief of the Oberkommando der Wehrmacht.
