Roosevelt Papers
The Assistant to the President’s Military Aide (Park) to the President’s Naval Aide (Brown)
Memorandum for Admiral Brown
There is given below a résumé of arrangements and plans with respect to the President’s Map Room for Octagon:
In general, the arrangements for the President’s Map Room for Octagon are the same as for Quadrant. The President’s Map Room will operate entirely independently of the Prime Minister’s Map Room.
The principal map on which we will show air and ground operations will be at the scale of 1 to 500,000, the same as the map on the north wail of the White House Map Room on which we are posting German troop dispositions. We are having this map made up especially for us to include the Western, Southern, and Eastern Fronts. For our fleet postings, a chart of the world has been procured, the same as on the east wall of the White House Map Room, which will be posted exactly as it is now. The remaining wall space at Octagon will contain the Asia map for coverage of Burma, China and Pacific Ocean theaters. We will, of course, bring with us complete information on fleet locations, Allied and enemy order of battle, and other pertinent information.
Captain Price departed Washington for Quadrant on Saturday, 2 September. As our advance man, he will see to the setting up of the room so that when the rest of the Map Room party arrive, they can go to work immediately. Lieutenant Collins and I will leave Washington [Page 35] on 6 September, taking with us all maps and material. Chief Yeoman Hoying will leave with the Presidential party.
The White House Map Room will operate as usual, under the command of Lt. Commander Tyree. Captain Kniffin will be in charge of the Army interests in my absence, and will go to the War Department twice daily for pick-up of dispatches.
Colonel, General Staff
