From  2nd from London # 5747.

       "We intend to begin on the first 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 succeed-
  ing, we make Mexico a proposal of alliance on the
  following basis:  make war together, make peace
  together, generous financial support and an under-
  standing on our part that Mexico is to reconquer
  the lost territory in Texas, New Mexico, and
  Arizona.  The settlement in detail is left to you.
  You will inform the President 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."  Signed, ZIMMERMANN.
