 The 71st Army of the Chinese Expeditionary Force set up defenses on the east bank of the Nu River, repeatedly frustrated the Japanese army’s attempt to move eastward, and thus stabilized the war situation, and confronted it across the river for two years.At that time, after the Burma Road, which was once the only land international transportation artery, was cut off, a large amount of military supplies to China could only be transported by the US Air Force through "The Hump" with much difficulty and no security.In order to regain control of the Burma Road, the six divisions of the Chinese Expeditionary Forces in India and the British and Indian forces jointly launched a counterattack against the Japanese army in northern Myanmar in late October 1943, and achieved initial results.
