In the latter part of March, 1917, a message from the Navy Department came to me at Newport, where I was stationed as president of the Naval War College, summoning me immediately to Washington. The international atmosphere at that time was extremely tense, and the form in which these instructions were cast showed that something extraordinary was impending. The orders directed me to make my visit as unostentatious as possible; to keep all my movements secret, and, on my arrival in Washington, not to appear at the Navy Department, but to telephone headquarters. I promptly complied with these orders; and, after I got in touch with the navy chiefs, it took but a few moments to explain the situation. It seemed inevitable, I was informed, that the United States would soon be at war with Germany. Ambassador Page had cabled that it would be desirable, under the existing circumstances, that the American navy be represented by an officer of higher rank than any of those who were stationed in London at that time. The Department therefore wished me to leave immediately for England, to get in touch with the British Admiralty, to study the naval situation and learn how we could best and most quickly co-operate in the naval war. At this moment we were still technically at peace with Germany. Mr. Daniels, the Secretary of the Navy, therefore thought it wise that there should be no publicity about my movements. I was to remain ostensibly as head of the War College, and, in order that no suspicions should be aroused, my wife and family were still to occupy the official residence of its president. I was directed to sail on a merchant vessel, to travel under an assumed name, to wear civilian clothes and to take no uniform. On reaching the other side I was to get immediately in communication with the British Admiralty, and send to Washington detailed reports on prevailing conditions.
