The Marco Polo Bridge Incident (盧溝橋事變; also known as 七七事變, 七七盧溝橋事變 or the Lugouqiao Incident) was a battle between the Republic of China's National Revolutionary Army and the Imperial Japanese Army, often used as the marker for the start of the Second Sino-Japanese War (1937–1945).
The eleven-arch granite bridge, Lugouqiao, is an architecturally significant structure, restored by the Kangxi Emperor (1662–1722).

Tensions between the Empire of Japan and China had been fanned since the Invasion of Manchuria in 1931 and subsequent creation of a puppet state, Manchukuo, with Puyi, the last monarch of the Qing Dynasty, as its sovereign. Although the Kuomintang (KMT) government of China refused to recognize Manchukuo, a truce between Japan and Republican China had been negotiated in 1931. However, at the end of 1932 the Japanese Army invaded Rehe Province (Jehol Province). This was annexed into Manchukuo in 1933.
Per the He–Umezu Agreement of 9 June 1935, China recognized the "neutrality" of eastern Hebei and Chahar provinces, though both were practically under Japanese occupation. Later that year, Japan officially established the East Hebei Autonomous Council, turning these regions into a puppet state and buffer-zone. By the start of 1937 all the areas north, east and west of Beijing were controlled by Japan.
Under the terms of the Boxer Protocol of 7 September 1901, China had granted nations with legations in Beijing the right to station guards at twelve specific points along railways connecting Beijing with Tianjin. This was to ensure open communications between the capital and the port. By a supplementary agreement on 15 July 1902, these forces were allowed to conduct maneuvers without informing the authorities of other nations in China.
By July 1937, Japan had expanded to maintain forces estimated between 7000–15,000 men, mostly along the railways. This number of men and amount of material was several times the size of those detachments deployed by European powers, and greatly in excess of the limits set by the Boxer Protocol.
Marco Polo Bridge, located outside of the walled town of Wanping (宛平鎮) to the southwest of Beijing was the choke point of the Pinghan Railway (Beijing-Wuhan), and guarded the only passage linking Beijing to Kuomintang-controlled areas in the south. Prior to July 1937, the Japanese military had repeatedly demanded the withdrawal of all Chinese forces stationed in this area, and had attempted to purchase nearby land to build an airfield. The Chinese refused, as Japanese control of the bridge and Wanping town would completely isolate Beijing from the Kuomintang-controlled south.
From June 1937, Japanese troops carried out intensive military training maneuvers in the vicinity of the western end of the Marco Polo Bridge. These were held every night (other foreign garrison troops seldom held night maneuvers), and the Chinese government requested that advance notice be given so that local inhabitants would not be disturbed. The Japanese agreed to this condition. However, on the night of July 7, 1937, night maneuvers were carried out without prior notice, greatly alarming the local Chinese forces.
Chinese troops, thinking an attack was underway, fired a few ineffectual rifle shots, leading to a brief exchange of fire at approximately 23:00. When a Japanese soldier, Private Shimura Kikujiro, failed to return to his post, his company commander, Major Kiyonao Ichiki, thought that the Chinese had captured him, and reported the incident to his regimental commander, Colonel Renya Mutaguchi. Chinese regimental commander Ji Xingwen (219th Regiment, 37th Division, 29th Route Army) received a telephone message from the Japanese demanding permission to enter Wanping to search for the missing soldier.
At 23:40, General Qin Dechun, acting commander of the 29th Route Army and Chairman of the Hebei-Chahar Political Council was contacted by Japanese military intelligence with the same demand. He responded that in his opinion, the Japanese had violated China's sovereignty by conducting maneuvers without advance notice, and refused the Japanese demand for entry into Wanping. However, Qin said that he would order Chinese troops stationed at Wanping to conduct a search on their own behalf with an attached Japanese officer. The Japanese were satisfied with the reply, but while both sides prepared their investigators, a unit of Japanese infantry attempted to breach Wanping's defences and were repulsed. An ultimatum by the Japanese was issued two hours later. As a precautionary measure, Qin contacted 37th Divisional commander General Feng Zhian to place his troops on heightened alert.
At around 03:30 on the morning of 8 July 1937, Japanese reinforcements in the form of four mountain guns and a company of machine gunners arrived from nearby Fengtai. The Chinese also rushed an extra division of troops to the area. At around 04:50, two Japanese investigators were allowed into Wanping. The presence of the Japanese investigators within the town notwithstanding, the Japanese Army opened fire with machine guns at around 05:00. Japanese infantry backed with armoured vehicles attacked the Marco Polo Bridge, along with a modern railway bridge to the southeast of town.
Colonel Ji Xingwen led the Chinese defences with about 100 men, with orders to hold the bridge at all costs. After inflicting severe casualties, the Japanese forces partially overran the bridge and its vicinity in the afternoon, but the reinforced Chinese soon outnumbered the Japanese. Taking advantage of mist and rain on the morning of 9 July, the Chinese were able to retake the bridge by 06:00. At this point, the Japanese military and members of the Foreign Service began negotiations in Beijing with the Chinese Nationalist government.
A verbal agreement with General Qin was reached, whereby an apology would be given to the Chinese; punishment would be dealt to those responsible; control of Wanping would be turned over to the Hopei civilian constabulary and not with the 219th Regiment; and better control of "communists" in the area. This was agreed upon, though Japanese Garrison Infantry Brigade commander General Masakazu Kawabe initially rejected the truce and continued to shell Wanping against his superiors' orders for the next three hours until prevailed upon to cease and to move his forces to the northeast.
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.
There are some disputes among historians over the incident. Some historians believe the incident was an unintentional accident. Some believe that the incident may have been fabricated by the Japanese Army in order to provide a pretext for the invasion of China—a thesis supported by the expansionist colonial ambitions of Japan at the time, reflecting a sentiment felt by many Japanese at the time that "Asia should be ruled by Asians," replacing European colonial rulers with Japanese rulers throughout Asia.
One far-right Japanese historian has alleged that the incident was staged by the Chinese Communist Party, who hoped that the incident would lead to a war of attrition between the Japanese army and the Kuomintang (Guomingdang).
Order of battle
National Revolutionary Army (Kuomintang)
In comparison to their Japanese counterparts, the 29th Route Army, and generally all of the NRA for that matter, was poorly equipped and under-trained. Most soldiers were armed only with a rifle and a Dadao. Moreover, the Chinese garrison in the Lugouqiao area was completely outnumbered and outgunned; it consisted only of about 100 soldiers. To make things worse, generalissimo Chiang Kai-shek was reluctant to provide assistance as he had grudges with the 29th Route Army commander, Song Zhe-Yuan.
