The first four days in London were spent collecting all possible data; I had no desire to alarm Washington unwarrantably, yet I also believed that it would be a serious dereliction if all the facts were not presented precisely as they were. I consulted practically everyone who could give me essential details and wrote a cable despatch, filling four foolscap pages, which furnished Washington with its first detailed account of the serious state of the cause on which we had embarked.[5] In this work I had the full co-operation of our Ambassador in London, Mr. Walter Hines Page. Mr. Page's whole heart and mind were bound up in the Allied cause; he was zealous that his country should play worthily its part in this great crisis in history; and he worked unsparingly with me to get the facts before our Government. A few days after sending a despatch it occurred to me that a message from our Ambassador might give emphasis to my own. I therefore wrote such a message and took it down to Brighton, where the American Ambassador was taking a little rest. I did not know just how strong a statement Mr. Page would care to become responsible for, and so I did not make this statement quite as emphatic as the circumstances justified. Mr. Page took the paper and read it carefully. Then he looked up. "It isn't strong enough," he said. "I think I can do better than this myself." He sat down and wrote the following cablegram which was immediately sent to the President: From: Ambassador Page. To: Secretary of State. Sent: 27 April 1917. Very confidential for Secretary and President. There is reason for the greatest alarm about the issue of the war caused by the increasing success of the German submarines. I have it from official sources that during the week ending 22nd April, 88 ships of 237,000 tons allied and neutral were lost. The number of vessels unsuccessfully attacked indicated a great increase in the number of submarines in action. This means practically a million tons lost every month till the shorter days of autumn come. By that time the sea will be about clear of shipping. Most of the ships are sunk to the westward and southward of Ireland. The British have in that area every available anti-submarine craft, but their force is so insufficient that they hardly discourage the submarines. The British transport of troops and supplies is already strained to the utmost, and the maintenance of the armies in the field is threatened. There is food enough here to last the civil population only not more than six weeks or two months. Whatever help the United States may render at any time in the future, or in any theatre of the war, our help is now more seriously needed in this submarine area for the sake of all the Allies than it can ever be needed again, or anywhere else.
