The British Embassy to the Department of State
Memorandum
The recent Allied Naval Conference in London recommended that steps should be taken to ensure the close cooperation between Allied Ministers in neutral countries with a view to making such representations as will ensure adequate action to prevent submarines or suspicious enemy vessels from being succoured or allowed to make use of territorial waters.
The British Embassy are instructed to ask that such instructions may be sent to the United States representatives in neutral countries. The French, Italian, Russian and Japanese Governments are being approached in the same sense.
