Event background
1In the second half of 926, the Guangdong National Revolutionary Army of the Northern Expedition made brilliant achievements in the Yangtze River valley and the battlefields in Jiangsu and Zhejiang provinces, and various imperialist forces, especially British imperialist forces, suffered heavy losses in China. In order to consolidate its power in the Yangtze River valley, the British government stepped up its intervention in the China Revolution. They not only dispatched a large number of warships to demonstrate in China, but also created bloody cases on the southeast coast; Moreover, they used their merchant ships to run amok in the Neihe River in China, making trouble and taking the sinking of China wooden boat and the drowning of China people as jokes. 1926 Within a short period of three months from June to August, the British Empire made four bloody cases in Wanxian section of the Yangtze River valley, successively sinking four China civilian ships and drowning more than 40 people.
