The President meantime was also confronted with the necessity of calling the new Congress into extra session, not so much to gain its assent to armed neutrality (since he had determined to act without it), but as a war expedient to support the measures projected against Germany. Owing to the Senate filibuster the previous Congress had been unable to pass appropriations exceeding $500,000,000, more than half of which was needed for the army. The new Congress was accordingly convened, to meet on April 16, 1917. CHAPTER LXIV GERMANY'S BID TO MEXICO While Congress was in the midst of its consideration of the Armed-Ship Bill, the Administration amazed the country by revealing through the press that Germany had made overtures to Mexico for an alliance with that country in the event of war with the United States, and also sought to involve Japan. This disclosure was due to American secret service agents, who had intercepted a communication addressed by Herr Zimmermann, the German Foreign Secretary, to Herr von Eckhardt, the German Minister at Mexico City, reading as follows: "BERLIN, January 19, 1917. "On the 1st of February we intend to begin submarine warfare unrestricted. In spite of this, it is our intention to endeavor to keep neutral the United States of America. "If this attempt is not successful, we propose an alliance on the following basis with Mexico: That we shall make war together and together make peace. We shall give general financial support, and it is understood that Mexico is to reconquer the lost territory in New Mexico, Texas, and Arizona. The details are left to you for settlement. "You are instructed to inform the President of Mexico of the above in the greatest confidence as soon as it is certain that there will be an outbreak of war with the United States, and suggest that the President of Mexico, on his own initiative, should communicate with Japan suggesting adherence at once to this plan. At the same time, offer to mediate between Germany and Japan. "Please call to the attention of the President of Mexico that the employment of ruthless submarine warfare now promises to compel England to make peace in a few months. "ZIMMERMAN."
