Zimmermann Telegram - Historical Post-script

Historical Post-script

The Telegram was not an isolated case of German-Mexican collaboration, for Germany had long sought to incite a war between Mexico and the U.S., which would have tied down American forces and slowed the export of American arms to the Allies. The Germans had engaged in a pattern of actively arming, funding and advising the Mexicans, as shown by the 1914 SS Ypiranga arms-shipping incident, and German advisors present during the 1918 Battle of Ambos Nogales. The German Naval Intelligence officer Franz von Rintelen had attempted to incite a war between Mexico and the U.S. in 1915, giving Victoriano Huerta $12 million. The German saboteur Lothar Witzke, responsible for the March 1917 munitions explosion at the Mare Island Naval Shipyard in the Bay Area, and possibly responsible for the July 1916 Black Tom explosion in New Jersey, was based in Mexico City. The failure of American troops to capture Pancho Villa in 1916, and the movement of President Carranza in favor of Germany emboldened the Germans to send the Zimmerman Note.

In October 2005, it was revealed that an original typescript of the deciphered Zimmermann Telegram had recently been discovered by an unnamed historian who was researching and preparing an official history of the United Kingdom's Government Communications Headquarters (GCHQ). The document is believed to be the actual telegram shown to the American ambassador in London in 1917. Marked in Admiral Hall's handwriting at the top of the document are the words: "This is the one handed to Dr Page and exposed by the President." Since many of the secret documents in this incident had been destroyed, it had previously been assumed that the original typed "decrypt" was gone forever. However, after discovery of this document, the GCHQ official historian said: "I believe that this is indeed the same document that Balfour handed to Page."
