During the Anti-Japanese War, in order to help the allied British troops fighting in Myanmar and ensure the smooth flow of the Yunnan-Myanmar highway and the smooth arrival of foreign aid materials in China's rear area, the National Government decided to send an expeditionary force to fight in Myanmar, shouting such impassioned slogans as "an inch of mountains and rivers and an inch of blood, 100,000 young people and 100,000 troops". China soldiers fought abroad for the first time, and wrote a magnificent chapter in the history of War of Resistance against Japanese Aggression, China, in the forest of northern Myanmar, which was filled with war and smoke. Later, due to the defeat of the war and the treachery of the British army, the Chinese Expeditionary Force was forced to leave Myanmar. Some of them had a hard time returning to China, while others retreated to British India, where they were reorganized into Indian troops stationed in China, trained in Ramga Training Camp and reorganized for one year.

A year later, Indian troops stationed in China counterattacked Myanmar. The first battalion of the lone advance team was besieged by intelligence errors and the arbitrary actions of Coalition commanders. In the face of the Japanese army ten times its own, 200 officers and men took a big banyan tree as their defensive position, fought bloody battles and repeatedly broke the enemy's front ... The eternal pride of an iron horse is also staged from now on!
