Diary of the Secretary of the Navy Josephus Daniels
March TUESDAY 6 1917
President called at Navy Dept. to talk over arming ships & danger of sub-marines in American waters & about bringing the fleet North - He thought, in addition to arming, we ought to have 3 motor boats on each ship to be lowered in Smooth seas & hunt submarines - When in England he saw the annual occasion where a shepherd would stand in a circle & by calls & whistles herd three sheep distant from him in a pen - It wasnt hard to manage 2, but very difficult with 3. They would expect a boat on each side of ship but the third boat would confuse them
