For the present our Division 8 with duty corresponding to Division 62 will base at Hampton Roads, though later some ships of the division may base at Halifax. Issue necessary instructions to put this plan into effect and furnish Department with rendezvous route. Directions will be given to Commander-in-Chief and Commander Cruiser Force3 to issue instructions from this end putting plan into effect immediately after.
