Vice Admiral William S. Sims, Commander, United States Naval Forces Operating in European Waters, to Admiral Sir Sydney R. Fremantle, R.N., Deputy Chief of Naval Staff
My dear Admiral,
I have looked into the matter of the depth below the surface of the mines that will be laid in the next expedition, (which will be the fourth), which leaves I believe next Monday or Tuesday.
These mines are all set for 65 ft. below the surface and of course it will be a delay of probably a week to change them all on board. The order has been given that the next batch and subsequent batches will be laid at a distance of about 45 ft. below the surface.
Very sincerely yours,
