The Admiral and his Staff very quickly established themselves in the high regard of British naval officers, and it was with much regret that we witnessed their return to the United States. My own associations with the Admiral had led to a feeling of great friendship. He left behind him his Chief of Staff, Captain Jackson, who to our great regret had been seriously injured in a motor accident. Admiral Benson's visit took place later in the year. I had written to him urging him to come across so that he might have first-hand knowledge of the state of affairs and of the policy being followed. During his visit the same questions were discussed as with Admiral Mayo, and important action was taken in the direction of closer naval co-operation between the Allies by the formation of an Allied Naval Council consisting of the Ministers of Marine and the Chiefs of the Naval Staff of the Allied Nations and of the United States. This proposal had been under discussion for some little time, and, indeed, naval _conferences_ had been held on previous occasions. The first of these during my tenure of office at the Admiralty was on January 23 and 24, 1917, and another was held during the visit of Admiral Mayo and at the instigation of the Government of the United States on September 4 and 5, 1917. On this latter occasion important discussions had taken place, principally on the subject of submarine warfare, the methods of dealing with it in home waters and in the Mediterranean, and such matters as the provision of mercantile shipping for the use of our Allies. There was, however, no regular council sitting at specified intervals, and it was this council which came into being in the early part of December. Its functions were to watch over the general conduct of the naval war and to insure co-ordination of the effort at sea as well as the development of all scientific operations connected with the conduct of the war. Special emphasis was laid upon the fact that the individual responsibility of the respective Chiefs of the Naval Staff and of the Commanders-in-Chief at sea towards their Governments as regards operations in hand as well as the strategical and technical disposition of the forces placed under their command remained unchanged; this proviso was a necessity in naval warfare, and was very strongly insisted upon by the Admiralty. The attention of the Council was directed at the earliest meetings to the situation in the Mediterranean, where naval forces from the British Empire, France, Greece, Italy, Japan and the United States were working, and where the need for close co-operation was most urgent. The real need in the Mediterranean, as was frequently pointed out, was the inclusion of the naval forces of all the Allied nations under one single command. In 1918 strong efforts were made to carry out this policy, and indeed the actual Admiralissimo was selected, but the attempt failed in the end.
