Marco Polo Bridge Incident - Aftermath

Aftermath

If the truce and ceasefire had remained in place, with both forces returning their original positions, the Marco Polo Bridge Incident would have ended as a minor skirmish. However, from midnight of July 9, Japanese and Chinese violations of the ceasefire began to increase, and a buildup of reinforcements on both sides continued, with four divisions of Chinese troops moved to the border, and three on the Japanese side. Confronted with the threat of another battle, General Kanji Ishiwara requested the Japanese government make public statements on the matter – which ironically were more hard-line than what the Kwantung Army had wished for. Prime Minister Fumimaro Konoe's statements threatened continued Japanese mobilization, even though Japan had begun pulling back its troops on the evening of the 11 July.

A lull in tension occurred when Lieutenant General Kanichiro Tashiro, commander of Japanese China Garrison Army, died of a heart attack on 13 July, and was replaced by Lieutenant General Kiyoshi Katsuki. Efforts to defuse the escalating conflict failed, largely due to actions by the Japanese Northern China Area Army commanders and militarists within the Imperial Japanese Army General Staff. Wanping was shelled on 20 July and full scale fighting erupted at Langfang on 25 July. After launching a bitter and bloody attack on the Japanese lines on the 27 July, General Sung was defeated and forced to retreat behind the Yongding River by the next day.

The Japanese gave Sung and his troops "free passage", then moved in to pacify areas surrounding Beijing and Tianjin. However, the Japanese Army had been given orders not to advance further than the Yongding River. In a sudden volte-face, the Konoe government's foreign minister opened negotiations with Chiang Kai-Shek's government in Nanjing and stated: "Japan wants Chinese cooperation, not Chinese land." Nevertheless, negotiations failed to move further than preparation as, on 9 August 1937, a Japanese naval officer was shot in Shanghai instigating the war proper.

Private Shimura Kikujiro was later found unharmed following the battle. He had become lost after relieving himself, and failed to make it back to his unit in time for roll call.
