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.
