The Zimmermann Telegram
On January 16, 1917, the Imperial German foreign minister, Arthur Zimmermann, sent a coded telegram to the German ambassador in Washington, D.C., Count Johann von Bernstorff, to be forwarded to the German minister in Mexico City, Heinrich von Eckhardt. Unknown to the Germans, the British had intercepted the telegram at their cryptanalytic center, known as Room 40, and were already decoding it.
