Secretary of the Navy Josephus Daniels to Vice Admiral William S. Sims, Commander, United States Naval Forces Operating in European Waters


RECEIVED  22 June 1917.                TO:- Alusna, London1


     For Vice-Admiral Sims. No. 22.


          The Bureau of Ordnance is now in a position to manufacture latest type of Admiralty mine2 or a superior type at the rate of four thousand per week beginning sixty days from now. It is the opinion of the Admiralty that possible future departments make it desirable that we construct a surplus supply for possible use in European waters, if so, how many do they suggest we ought to manufacture? Would the Admiralty like to have us manufacture nets for use over there? If so, send details at once. Has a mine not effective against surface craft but effective against submarines ever been under construction? Are there any plans of future contemplated operations that we could be supplied with?3    16022.


              Sec. Navy
