Source Note: Cy, UK-KeNA, Adm. 137/1426. The cable is only signed with the code name “2010” but from the heading it is clear it is from Adm. Montague E. Browning. The copy is done on a form so portions of the heading are printed. There is another copy in DNA, RG45, Entry 517. At the bottom of the first page of that copy in the left margin is typed: “1st.L./1st S.L./Sir H.Wilson./D.O.D./D.I.D.” This presumably means that copies of the cable were distributed to: First Lord of the Admiralty Sir Edward H. Carson; First Sea Lord Adm. Sir John R. Jellicoe; Sir Henry Wilson, Chief of the Imperial General Staff; Director of the Operations Division of the Admiralty RAdm. Thomas Jackson; and Director of the Intelligence Division Capt. William E. Hall. After the report is a handwritten note by Chief of the War Staff VAdm. Henry F. Oliver, dated 28 April 1917, which reads: “The squadron for the North Atlantic is small but possibly if we get intelligence of a raider they may rise to the occasion & supplement it. The Conference has been very Satisfactory.”

The first American destroyers were based in Queenstown (Cobh), Ireland.
Footnote 7: Nitrates, of which Chile had a rich supply, were important in the production of armaments and fertilizer for agriculture.
Footnote 8: On the same day, the U.S. naval attaché in London, William D. MacDougall, reported that Adm. William S. Sims believed it probable that the Germans would send a “few” mine-laying submarines to operate on the coast of the United States. See: MacDougal to ONI, 13 April 1917. On 7 April, the British Admiralty cabled its naval attaché in Washington, Capt. Guy R.A. Gaunt, that the British Navy had obtained “some” success “using some of our submarines against similar hostile craft” and that the Admiralty would welcome U.S. submarines operating in “the vicinity of West Indies or Canadian coast” should German U-Boats “appear there.” Anglo-American Naval Relations: 29-30.
