The Battle of Mount Song or Battle of Ramou (Chinese 松山战役, Japanese 拉孟の戦い)in 1944 was part of the largest campaign in southwestern China during the Second World War. Chinese Nationalist forces aimed to retake control over the Burma Road. The Japanese were losing the war in Burma and aimed to block off the highway connecting China with Burma for as long as they could. Using slave labour from Thailand and Burma they constructed a series of tunnels and bunkers in order to turn the mountain(松山)into a fortress.

The Chinese forces were unaware of the depth of the Japanese defenses, and their underestimation led to heavy casualties. Chinese artillery strikes and US bombing runs had little effect against Japanese forces underground. After initial defence the Japanese command in Northern Burma ordered the majority of the garrison out and left 1400 men (including 300 wounded and 20 comfort women) to defend the mountain top. This encircled group under the command of Major Kanemitsu Keijirou held out and denied the use to the American-Chinese Armies for a further three months.

Japanese attempts to resupply the unit by air on two occassions led to most of the supplies falling into Chinese hands. This was the only occassion where Japanese troops besieged were supplied by air.

Chinese forces finally retook Mount Song through the use of continual bombardment, American airpower and overwhelming numbers of Chinese infantry. In the end the Japanese faced overwhelming force numbering the attackers at 50 Chinese soldiers for every Japanese defender.

Fall and Aftermath[edit]

The Japanese list only one survivor, Captain Kinoshita, an artillery officer ordered out to communicate to Japanese high command the night before the fall of the outpost. Chinese sources say from 7 soldiers were captured out of the total garrison. About 12 Japanese comfort women committed suicide towards the end of the siege. Five to Six Korean comfort women were captured by Chinese and US forces. [2]

After its capture the Burma Road could be used once again.

Although a Chinese victory the small Japanese force unsupplied and lacking air power or heavy artillery held up the entire Chinese Expeditionary Army for over three months considerably lengthening the war in Burma.[3]


Accounts of the battle exist in Japanese and Chinese. There has been virtually no recorded reference to this battle in any detail in English sources outside of initial battle reports. It remains a largely forgotten event in the Burma War.
