Telegram from the President of the United States [Franklin Roosevelt] to WSC expressing his concern over plans to limit shipments of supplies to the Soviet Union: asks WSC to review the size of immediate convoys; hopes that Anthony Eden [Foreign Secretary, later 1st Lord Avon] will avoid giving the Soviet Ambassador [Ivan Maisky] any flat statement about the limit to the number of ships that can be convoyed; "It seems to me that any word reaching [Joseph] Stalin at this time that our supplies were stopping for any reason would have a most unfortunate effect".
