10. Zimmerman Telegram (Don’t Write) Most Secret For Your Excellency's personal information and to be handed on to the Imperial Minister in Mexico We intend to begin unrestricted submarine warfare on the first of February. We shall endeavor in spite of this to keep the United States neutral. In the event of this not succeeding, we make Mexico a proposal of an 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 detail is left to you.

11. Zimmerman Telegram (Don’t Write) You will inform the President [of Mexico] of the above most secretly as soon as the outbreak of war with the United States 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 unrestricted employment of our submarines now offers the prospect of compelling England to make peace within a few months. Acknowledge receipt. Zimmerman
