Immediately after the failed assassination attempt on Hitler on July 20, 1944, it was decided to print a "Das Neue Deutschland Extra" edition, which was issued in 50,000 copies. This was intended to respond as quickly as possible to the dramatic events that had almost led to a coup in Germany. In order to distribute this Extra edition, people in full Wehrmacht uniforms were successfully deployed for the first time to infiltrate the German lines. This action was called Operation Sauerkraut.
