The Battle of Songhu (also known as the Battle of August 13th; Japan claims that the Second Shanghai Incident [2] broke out in August 1937. It was a battle launched by Chiang Kai-shek in Shanghai after the Lugouqiao Incident, with the aim of changing the direction of Japanese invasion from north to south and from east to west, so as to facilitate long-term operations and attract the attention of the international community. This is the first important battle between War of Resistance against Japanese Aggression, China and Japan, China and the whole China and Japan. This campaign marked the real beginning of a full-scale war between the two countries without declaring war, and the regional conflict after the Lugouqiao Incident escalated into a full-scale war. The use of the word "Incident" seriously underestimated the Japanese aggression against China.

The battle was fought in the urban and suburban areas of Shanghai, the largest city in the Far East at that time. Only the French Concession in Shanghai and the half of the Shanghai Concession south of Suzhou River are armed and neutral, and they are divided into defense zones of French, British, American and Italian troops respectively. Gongxian Concession to the north of Suzhou Creek and its cross-border road-building area belong to the Japanese defense zone and are the operational bases of the Japanese army in Shanghai. China and Japan have about 6,543,800 troops fighting.

The campaign itself lasted for three months, and the tactical actions of government forces can be divided into four stages: "attacking, blocking, defending and retreating". Where does the first stage begin? From August of 13 to September of10/3, the National Revolutionary Army took the lead in attacking the Japanese Concession with its 87th Division, 88th Division and 36th Division in an attempt to annihilate the Japanese troops in the Concession. However, the Japanese army could not be reduced, which led to the reinforcement and counterattack of the Japanese army. The two sides continued to increase their troops, so the front line was in a stalemate. In the second stage, from September to June in 12165438+14 October, the two armies were involved in bloody street fighting for the control of the city.
