November 27th, 1941, War Warning

At 1430 [2:30 P.M.] on November 27th, Colonel Tige Phillips, General Short’s Chief of Staff, brought War Department Message No. 472 to General Short. This message, signed by General Marshall, read as follows:

Negotiations with Japan appear to be terminated to all practical purposes with only the barest possibilities that the Japanese Government might come back and offer to continue. Japanese future action unpredictable but hostile action possible at any moment. If hostilities cannot, repeat cannot, be avoided the United States desires that Japan commit the first overt act. This policy should not, repeat not, be construed as restricting you to a course of action that might jeopardize your defense. Prior to hostile Japanese action you are directed to undertake such reconnaissance and other measures as you deem necessary but these measure should be carried out so as not, repeat not, to alarm civil population or disclose intent. Report measures taken. Should hostilities occur you will carry out the tasks assigned in Rainbow Five [the Army’s basic war plan] so far as they pertain to Japan. Limit dissemination of this highly secret information to minimum essential officers (Prange 402).

Upon receiving this message, General Short convened a meeting with his staff to discuss the implications. This meeting included:

“Well gentleman, how should we respond to this message?” asked General Short. “It says hostile action may be possible at any time. But it doesn’t mention anyplace specific. Do we have any intelligence regarding possible targets Colonel Fielder?”

“No, Sir, not at this time,” replied Fielder.[continued on next page]
