1588. Information received from Secret Service sources indicates that a large number of German personnel is being sent to Pola to assemble and man German submarines for duty in the Mediterranean. In view of the fact that a number of our vessels are being sunk in that area and that this area, due to winter weather and other circumstances, promises to be the one where most active operations by German submarines will in all probability take place, I shall unless otherwise directed order the yachts now enroute to Europe to proceed from the Azores to Gibraltar for duty in the Mediterranean. Should there be any objection to this action immediate answer is requested. Signed Benson. 13320
