The Zimmermann Telegram
The Ambassador of Great Britain [Walter Hines Page] to
the Secretary of State [Robert Lansing]
LONDON, February 24, 1917, 1 P.M. [Received 8:30 P.M.] . . . [British Foreign Secretary Arthur] Balfour has handed me the text of a cipher telegram from [Arthur] Zimmermann, German Secretary of State for Foreign Affairs, to the German Minister to Mexico. . . . I give you the English translation as follows:
"We intend to begin on the 1st of February unrestricted submarine warfare. We shall endeavor in spite of this to keep the United States of America neutral. In the event of this not succeeding, we make Mexico a proposal of alliance on the following basis: make war together, make peace together, generous financial support and an understanding on our part that Mexico is to re-conquer the lost territory in Texas, New Mexico, and Arizona. The settlement in detail is left to you. You will inform the President [of Mexico, Venustiano Carranzal of the above most secretly as soon as the outbreak of war with the United States of America is certain and add the suggestion that he should, on his own initiative, invite Japan to immediate adherence and at the same time mediate between Japan and ourselves. Please call the President's attention to the fact that the ruthless employment of our submarines now offers the prospect of compelling England in a few months to make peace."
The receipt of this information has so greatly exercised the British Government that they have lost no time in communicating it to me to transmit to you, in order that our Government may be able without delay to make such disposition as may be necessary in view of the threatened invasion of our territory. . . .
