Source Note: Cy, UK-KeNA, Adm. 137/655. There is a columnar list (without punctuation) at the bottom of the cable copy giving who in the British Admiralty received this cable. That list includes: “1st. L; 1st S.L.; D.O.D; D.A.S.D; D.I.D.” That is First Lord of the Admiralty (Sir Edward H. Carson); First Sea Lord (Adm. Sir John R. Jellicoe); Director, Operations Division (RAdm. Thomas Jackson); Director, Anti-Submarine Division (RAdm. Alexander L. Duff); and Director, Intelligence Division (Capt. William R. Hall).”

Footnote 1: Commo. Guy R. Gaunt, British Naval Attaché at Wasington, D. C., who delivered the cable to the U.S. Navy.

Footnote 2: This means that cipher “L” was used to encode this letter.

Footnote 3: Division Eight was the first destroyer division to be sent to Queenstown (Cobh); it arrived there on 3 May.

Footnote 4: Division Nine was the second destroyer division to arrive, arriving at Queenstown on 17 May.

Footnote 5: Melville arrived on 22 May. Berehaven was a small port on the southern tip of Ireland on Bantry Bay and some seventy-five miles from Queenstown. It was used as an advance base for the force stationed at Queenstown.

Footnote 6: Presumably, Bayly means submarines. Kinsale is a port on the southern coast of Ireland in County Cork, some 20 miles west of Queenstown. The third division of USN destroyers arrived at Queenstown on 24 May. See, Diary of Joseph K. Taussig, 24 May 1917, RNW, Joseph K. Taussig Papers, Mss. Coll. 97, Naval Historical Collection.

Footnote 7: VAdm. William S. Sims, Commander, United States Destoryers Operating from British Bases, also served as the American liaison to the British Admiralty. In his diary entry for 25 May, Secretary of the Navy Josephus Daniels wrote: “Sims wired Germans knew of our torpedoes [i.e., destroyers] going over & had mined the harbor where they had their base. Necessary to be vigilant to keep movements secret. This shows it to be needed.” DLC-MSS, Josephus Daniels Papers, Diary, Roll 1.
