What is the specific content of the battle of Songhu?

The bridge incident triggered the end of the war.

After the Japanese imperialists occupied Peiping and Tianjin, they actively planned to attack Shanghai, repeating their old tricks and provoking troubles. First, on July 24th, the Japanese Marine Corps stationed in Shanghai suddenly claimed that a soldier was missing, creating a tense atmosphere. Soon, the soldier was caught and sent back to the Japanese consulate. Japan also took the opportunity to retreat from Shanghai to prepare for the war.

At 5: 30 pm on August 9, Japanese Marine Corps lieutenants Yukio Dashan and Saito tried to hide two men and drove a military vehicle to Hongqiao Airport, where they were killed by airport guards. After the incident, Yu Hung chun, Mayor of Shanghai, and Zhou Jue, Secretary of the Ministry of Foreign Affairs of the National Government called the Japanese Consul General in Shanghai and the Japanese Navy respectively. At that time, the Japanese side said that the officers and men of the Japanese Marine Corps did not receive an order to go out today. Even if someone goes out, they will never go to Hongqiao Airport. Because Japanese officers and men should never go to the airport.

That night 10, Mayor Yu Hongjun went to the Consulate General in Japan to make representations, described the incident and advocated a diplomatic solution to prevent the incident from expanding. The Japanese side also agreed. However, at 4 pm on June 5438+0 1, Japanese Consul General Okamoto visited the mayor, and his attitude turned tough, claiming that the Japanese nation was extremely shocked by the killing of the second Japanese soldiers by Hongqiao. Although the Tokyo government agreed to solve the problem through diplomatic channels, it also thought it necessary to "question" China's attitude towards the case. There are two additional requirements: "(1) withdraw the security team, and (2) completely dismantle the fortifications built by the security team."

Yu Hung chun replied: "Since it is China's land, there is no need to retreat." . All measures taken for fortifications and "security teams" are only for prevention. In short, the Japanese side should be able to understand our intention to maintain peace ... If the Japanese side can also abide by the scope, conflicts will naturally be avoided. " The Japanese side expressed satisfaction.

At 3: 00 p.m. on June 5438+02, at the request of Japan, a meeting was held with Songhu Armistice Agreement Committee. The meeting was held in the conference hall of the Ministry of Industry and Commerce of China Concession. In addition to China and Japan, there are representatives from Britain, France, the United States and Italy. Japanese representative Okamoto claimed that this morning, Japanese security forces and regular troops had set up fortifications in the suburbs. This kind of behavior violates the armistice agreement, so please pay attention to it and take effective measures to stop it. Yu Hung chun immediately retorted: "The purpose of the Committee is to maintain peace and order in Shanghai, not to assist the Japanese government's aggressive policy." . "After the Hongqiao incident, the Japanese side repeatedly said that it would wait for an investigation of the truth and a diplomatic solution, but on the one hand, warships gathered, the army increased greatly, and the military supplies were also greatly supplemented. In addition, a large number of warships are on their way and keep coming. Such measures not only hinder the safety of nationals of various countries, but also pose a threat to China, which is enough to cause harmful acts. China has the right to act in self-defense within its own territory. ..... We adhere to the consistent policy of the Central Committee. No one will attack me, and I will not attack. We still have to protect overseas Chinese living in Shanghai. " Delegates suggested that the security team could step back a little to avoid conflict. Yu Hung chun replied: "The armistice agreement has long been broken by the Japanese side, and there is really no need to convene a Committee today." "Our army has the absolute freedom to move on its own land, but this is not allowed to be discussed by others." "In order to maintain peace and order in Shanghai, if Japan brings back additional warships and troops, we are also willing to consider withdrawing the guard." The meeting ended without results.

At the meeting, Japan said that it would try its best to avoid war, but it was ready for war in action. Japanese marines landed one after another on the evening of 12. But also in Yangshupu, Zhabei and Hongkou. By the end of 12, Songhu had mobilized more than 30 Japanese ships, including navy and marine corps15,000 people. 1On August 9, 937, two officers and men of the Chinese Marine Corps drove into Hongqiao Airport for armed provocation, and were immediately killed by the Japanese defenders. On August 13, the Japanese army used this as an excuse to attack Shanghai on a large scale. 18 At 9: 00 a.m. on August 3, the Japanese Marine Corps, under the cover of armored vehicles, set out from the former site of Baoshan Road Commercial Press, crossed the Songhu Railway at Hengbang Bridge, headed for my position on Baoshan Road and fired at my position. In self-defense, our security team fired machine guns and beat back the enemy. Five Japanese soldiers were killed and more than 65,438+00 people were injured. At 3: 50 pm, the Japanese army began a large-scale attack and bombarded it with artillery. Our army fought bravely. The Ninth Army of the Chinese Army led by Zhang Zhizhong rose to resist. The Kuomintang government mobilized more than 700,000 people from six group armies to participate in the war and won the first battle. Since August 23, the Japanese army has landed in the Yangtze River estuary for many times, attacking the left wing of the defenders and encountering stubborn resistance. Subsequently, the Japanese army sent more troops one after another to strengthen the power of sending troops to Shanghai. China's army has been reinforced and constantly adjusted its deployment. After 911,Chiang Kai-shek became the commander-in-chief of the third war zone. From late September to1early October, Japanese reinforcements landed in Shanghai one after another. At dawn on September 30th, the Japanese army stormed the China army, and the China garrison was in a bitter struggle, with heavy casualties. 1On the evening of October 26th, more than 400 people from the 2nd Battalion of the 524th Regiment of the 88th Division of the Chinese Army (advertised as "eight hundred heroes" by the press) were ordered to set up a fourth-line warehouse on the north bank of Suzhou Creek under the command of Xie Jinyuan, the deputy head of the regiment, and Yang Ruifu, the battalion commander, to cover the evacuation of the main force overnight. Under the heavy encirclement of the Japanese army, the China army guarding the four-row warehouse fought alone for four days and nights, repelling dozens of enemy attacks under the cover of planes, tanks and artillery. 1 1 On May 5th, a Japanese army landed in Hangzhou Bay, detoured to the defenders and besieged Shanghai. The defenders were forced to retreat. 1 1 month 12, Shanghai fell.
