Military History of Vietnam - Sino-Vietnamese War

Sino-Vietnamese War

The Sino-Vietnamese War was a Chinese attempt to force Vietnam out of Cambodia. China launched invasion of Vietnam, but faced much tougher resistance than expected. The Chinese invasion lost its progress relatively quickly. The Vietnamese conducted cross-border raids and succeeded in disrupting the Chinese fire support. When the initial offensive had been halted, a new wave of attack was sent in, and eight Chinese divisions were sent into Vietnam. The Chinese penetrated 15–20 km into Vietnamese territory at most, but the price of human life and equipment were very high. Vietnam did not mobilize its regular divisions, which was ment to protect Hanoi if necessary, and no troops were pulled out of Cambodia during the war. In Lang Son, the hardest battles took place. The city was heavily fortified by the Vietnamese Army, and it took 17 counterattacks before the Chinese were able to capture the city. The Vietnamese troops pulled out of the city itself, but established heavy positions in the surrounding mountains. Soon after, Deng Xiapong announced that China would pull out its forces. 25 Chinese Divisions of the Third Field Army had been taking part of the invasion. Not a single Vietnamese Regular Division had mobilized, and the Chinese invasion did not affect the Vietnamese presence in Cambodia. In less than a month, according to Western sources, the Chinese Army had suffered some 26,000 KIA and 37,000 WIA. Both sides claimed victory.
