Marco Polo Bridge incident

The Battle is well known among Chinese as Incident of July 7 (七七事變) or July 7 Lugouqiao (七七蘆溝&#27211). (note: All Chinese and Japanese personal names here are preceded by family names.)

Overview
On July 7 1937, Japanese Imperial Army attacked the bridge. Despite determined resistance by KMT forces, Japanese army managed to take the bridge and eventually Beijing which is abandoned by KMT.

Historical significance

The battle officially marked Japanese large scale invasion of China. With the Japanese victory the Imperial Army can move on to the plain of Northern China without much resistance since the tanks are pretty formidable against the low-tech Chinese army.

Prelude to Battle

After the Incident of September 18 in 1931, Japan had occupied Manchuria and had created an nominally independent state of Manchukuo with Ai-xin-jue-luo Pu-yi (the last emperor of China) as its sovereign. That state is widely regarded to have been a puppet government with real power concentrated in the hands of the Japanese, which constituted the only significant military forces in Manchuria. Although the Kuomintang and the international community refused to recognize the legality of the Japanese occupation, a truce had been negotiated in 1931.

At the end of 1932, Japanese Guandong Army invaded Chahaer Province. KMT's XXIX Corp., lead by General Song Zhe Yuan and armed only with spears and obsolete rifles, resisted the aggression, resulting in the War of Resistance at the Great Wall. The province fell to the Japanese after the predictable victory.

In 1933, Japan annexed Rehe Province using the security of Manzhouguo as a pretext. As a result all areas north of the Great wall fell to Japan. In 1935, Japan annexed eastern portion of Hebei Province, established yet another puppet government, Eastern Ji Anticommunist Automated Government (冀東防共自治政府 abrreviated as Eastern Ji Automated Government 冀東自治政府). Later the year, Ho Ying Qin (何應欽) and Umemura mi?rou (梅村美治/自郎) signed an agreement, known as the Ho-Umemura Agreement by which Japanese could deploy and pratise troops around Beijing at will. As a result at the start of 1937, Beijing was surrounded at north, west and east by area occupied by Japanese.

Installations of various puppet governments were deliberate attempts by the Japanese to annex whole country of China by nibbling. Nanjing puppet government with Wang Jingwei as head was another obvious example.

Geography around the bridge and Beijing

Lugou Bridge ( 蘆溝橋 lugouqiao) locates in Fengtai (豐台 feng1 tai2), a suburb area south of Beijing. It is also known as the Marco Polo Bridge because it was believed that this bridge was described in the works of Marco Polo.

4 strategic posts secured Beijing from outside the city.

East of the city: Tongzhou Town (通州鎮)
Northwest: Nankou Town (南口鎮) at Changping Prefecture (昌平縣xian)
South: Fengtai Town (豐台鎮)
Southwest: Lugou Bridge at Wanping Prefecture (宛平縣). The bridge guraded the only passage leading Beijing to outside and KMT-controlled area from the south. Pinghan Railway (Beijing-Wuhan Railway), the only rail linking up the city to south of Huang he, was also on the bridge.
Before the start of the battle, all the first 3 posts were under Japanese control except the southwest. If the bridge fell, the city will be completely cut off from KMT who thus defended it at all costs.

Phase II

Course of the Battle

Beginning late June 1937, the Japanese army (several 100)deployed at the west end of the bridge was practising while Kuomintang forces, garrisoned in Yuanping Prefecture which located just east of the bridge, watched closely. In the evening of July 6, the Japanese army telegraphed the Kuomintang forces saying that a soldier was missing and believed to be hiding inside the town. The Japanese demanded that its army should enter the town to search for the missing soldier, who was later found unharmed. There are some disputes among historians over the incident with some historians believing that this was an unintentional accident while others believing that the entire incident was manufactured by the Kwantung Army in order to provide a pretext of the invasion of central China.

Colonel Ji xing-wen (吉星文), commander of the Kuomintang forces (XXIX Corp, 37th Division head: feng ji an rule safe, hobei province chairman, , ) of the area at the time, denied the request backed by his superior, Commander-in-chief(?) of all forces of the Hebei province, General Song On July 7, Japanese(Matsui Taisa = Colonel Matsui 松(matsu) 井(i) 大(tai) 佐(sa)) gave Ji an ultimatum that Kuomintang troops must let japanese troops enetr the town to search within 1 hr or the twon will be fired but japan artillery has already aimed at the toen when the ul was sent. At midnight July 7, Japanese artillery units started bombarding the town while the infantry with tanks matched across the bridge at dawn With order from General Song, Captain Ji led the KMT forces of about 1000 defended at all cost) july 12, meeting of all important personnel of XXIX corp at beijing. general qin prefer defend whereas zhang argue the incident can still be settled by negotiation. japan head of all force in hua north (cha, yeh, ping, and jin) bridge ben told zhang that japan hope incidence of luguo bridge can be settled peacefully. The negiotiation (obvious time buyer) took place at tianjin. as it goes on, japan concentrated armies from Manchuria and Korea around Beijing. Song send qin and general zhao ding yu (zhao escalate water woman) head of 132th division to guard nan yuan (north of yuanping town, the passage and pinghan railway goes thorugh the bridge, yuan ping, nan yuan then into Beijing.) japana partially overran the bridge but KMG force retook it completely next day. Then japan army stop the attack, and offer negotiation. But japanes army still concentrte at the west end. resisted the attack which lasted for 3 weeks. On the diplomatic front, General Song, who was also the chairman of the province, sent a negotiator, Zhang self faith (38th division head major of tienjin shengdong people from lin (wood) qing(clean) prefecture), to nan yuan (south of yuan ping) Japanese headquarters while the fight was still taking place.

negotiation:

japan want (if KMG agrees all terms, japan promised not to invade beijing and tienjing):

clear anti-japan organaization, anti-japan activities. (KMG=OK) held KMG resposible for july 7 incident (KMG: fired the yin head) wants song's apology and relieve himself. (Zhang: cannot decide on behalf of song, retruned to beijing.) As soon as zhang's leave, japan lauched full scale attack on Beijing. (july 28?)

nan yuan loss to japan (aug 3?, zhao's sacrifice), zhang arrival in beijing aug3. song relieved himself as committee leader, head of beijing police. appoint zhang as beijing mayor,, police head and committe leader. and left beijing (aug 5),

The negotiation stalled as the Japanese insisted KMT forces must stop the resistance unconditionally and retreat from the town. Song's stance of not giving up an inch of land was also a factor. Evetually the Japanese promised Zhang that no more similar sort of incidence would take place in the future. Then Song ordered Ji's retreat to Beijing, marking the end of the battle. However, the Japanese broke the promise a month later and invaded the city which fell on October 15 (?) 1937.

Aftermath

aug fell to japan aug 15?., tienjin on aug 17?

2 views:

Zhang and Song set-up: zhang was appointed of all the above post while song and qin took the main force of corp XXIX out of beijing, keep shili (fact strength).

japan cheated zhang that even KMG accepted all demands but japan still invade beijing, tienjin.

Media (like Shanghai Daily) scolded Zhang as traitor of the country.

Zhang was not treated as traitor (or being forgiven) since he sacrified himself while fighting in Anhui.

With the loss of the bridge and, consequently, Beijing and Tianjin, the plain of Northern China was helpless against Japanese machanized divisions who occupied it by the end of the year. Chinese armies (KMT and CCP) were on constant retreat until the hard fought Chinese victory at Tai er zhuang.
