Vice Admiral William S. Sims, Commander, United States Naval Forces Operating in European Waters, to Secretary of the Navy Josephus Daniels
SENT. June 7th. 1917. TO: Secretary of Navy (Operations)
7. Total loses ending week June third, 122,628 (one hundred and twenty-two thousand six hundred and twenty-eight) tons. General activity about same as last week except to north and north west Scotland and Ireland where it was more intense. Evidence indicates fourteen large boats out ten in area to west of five degrees longitude. Of these six concentrated in northern exit route from Irish Sea and by so doing held up all traffic on that route. The above fourteen includes only those submarines on station and not those on way back, and out and those bound to Mediterranean. Mining submarines apparently concentrating on east coast [of Ireland] during week. New type mine now discovered in Firth of Forth now under investigation. One report of smoke emitting submarine as if steam propelled. First ocean convoy from Hampton Roads now in danger zone. Another left Hampton Roads under escort Carnarvon fourth June. Twenty one encounters with submarines during week three by destroyers one American two special service ships two cruisers eight auxiliary patrol one submarine three seaplanes two merchant ships. Request information of any further additions to our forces here or in France and prospective dates sailing. The great necessity [is] in numbers of anti-submarine craft[;] the greater the number the more effective the offensive campaign. Also request g<e>neral information as to Departments’ policy concerning Fleet and other service vessels. Nothing now under consideration as regards their possible use this side, but would like to be generally informed in case future developments or emergencies should bring the question up.
