X-WR-CALDESC:20 March 1938: SIS began receiving messages from Purple - a Ja
 panese Cipher machine. Pictured here is a photo of the largest of three su
 rviving pieces (telephone selector switches) of the famous Japanese diplom
 atic ciphering machine. It was recovered from the wreckage of the Japanese
  Embassy in Berlin\, 1945. \n\nPURPLE was the second of two Japanese diplo
 matic machine-generated cipher systems broken by the U.S. Signals Intellig
 ence Service (SIS). In 1935\, the SIS successfully broke Japan's machine p
 roduced RED system. In 1938\; however\, Japan began using a more complex a
 nd challenging system that the SIS referred to as PURPLE. In time\, throug
 h a combination of hard work and effort\, the SIS team met with success. T
 he secret diplomatic communications of the Japanese Empire\, hidden behind
  the PURPLE ciphers\, were now open to the Americans. These decrypted mess
 ages\, marked 'Top Secret MAGIC\,' gave senior American decision makers in
 sight into the thinking and policy of Japanese government officials in the
  days and months leading up to the attack on Pearl Harbor. However while t
 he information contained in MAGIC gave select US and military leaders insi
 ght into future Japanese intentions on a broad level there was no specific
  information in MAGIC that would have enabled America to predict the attac
