The Counselor of Embassy in China (Peck) to the Secretary of State
[Received July 22—5:46 a.m.]
317. An American-educated Chinese Army officer who is acting as liaison between the Chinese General Staff and foreign military attachés yesterday informed me that long before July 7 the General Staff knew that the Japanese felt that their military force at Fengtai was seriously exposed to attack and wished to get possession of Nanyuan airdrome-Marco Polo Bridge areas. He said also that the Chinese military headquarters in Peiping had reported to Nanking 10 days before the bridge incident, and the Japanese authorities had warned Japanese in Peiping that an event necessitating precautions on their part would occur before long.
Repeated to Peiping.
