[Enclosure]19

Message From General Chiang Kai-shek Received Today, October 30

Definite information reached me Japanese design attack Yunnan in November. [(1)] This move may possibly be averted if America takes immediate action by informing Japan that attack Yunnan through Indo-China would be viewed by America as definite step in southward expansion and that America cannot remain indifferent. Simultaneously military preparations should be made to meet this eventuality. I must emphasize the critical nature of the Yunnan situation since if Yunnan is lost and last life line for materials from the outside world severed the Chinese people and Army materially and morally would be unable to offer further armed resistance. I am confident with forces in Yunnan and available nearby Chinese able to hold their own land fighting if reinforced airward. Colonel Chennault has only 49 pilots consequently strong air reinforcement essential. [(2)] Urge America use strong pressure on Britain to send Singapore air force to cooperate with Colonel Chennault in order save democratic position in Far East. Britain and America equally concerned to prevent loss of Yunnan as Chinese because if Japanese occupy [Page 741] Yunnan their next stop [step] would involve attack on British Far East colonial possessions and precipitate war in the Pacific. If immediate action taken by Britain in sending air reinforcement these possessions would be saved at a fraction of the cost that their defence would involve later on and Pacific problem would thus be solved. Japanese will concentrate largest air force in Indo-China and if [this were] destroyed [by the] combined air forces [the] threat to Far East [would be] finally removed.

  1. President Roosevelt on about October 30 transmitted Mr. Morgenthau’s letter with enclosure in a note to the Secretary of State: “C. H. Can we do anything along these lines? How about telling Japan a move to close Burma Road would be inimical? F. D. R.”
