On August 9 1937, First Lieutenant Isao Oyama of the Japanese Marines attempted an illegal entry into the Hongqiao Airport  of Shanghai, but was shot to death by the Chinese Peace Preservation Corps stationed near the military airport. It is still unknown whether Oyama initiated the intrusion on his own or acted on higher orders. Regardless, the Oyama Incident certainly heightened the tension in Shanghai
