Vice Admiral William S. Sims, Commander, United States Naval Forces Operating in European Waters, to Secretary of the Navy Josephus Daniels
August 29, 1917.
From: Force Commander.
To: Secretary of the Navy (Operations).
Subject: British Method of controlling Neutral Shipping.
The British Government has provided insurance for a large number of neutral vessels that are carrying cargoes to the Allies and operating in dangerous waters. As a return for this insurance, the British insist that these Neutrals must be guided by British instructions, or the insurance will be withdrawn. On this basis, Neutrals are regularly placed in convoys, follow British instructions, and in a sense are under British discipline.
Any neutral not insured by the British Government, but carrying cargo to the Allies, is accepted in the convoys.
Wm S. Sims.
