Sino-Indian border dispute
The Galwan river is to the west of China's 1956 claim line in Aksai Chin. However, in 1960 China advanced its claim line to the west of the river along the mountain ridge adjoining the Shyok river valley. Meanwhile, India continued to claim the entire Aksai Chin plateau.
These claims and counterclaims led to a military standoff in the Galwan River valley in 1962. On 4 July, a platoon of Indian Gorkha troops set up a post in the upper reaches of the valley. The post ended up cutting the lines of communication to a Chinese post in Samzungling. The Chinese interpreted it as a premeditated attack on their post, and surrounded the Indian post, coming within 100 yards of the post. The Indian government warned China of "grave consequences" and informed them that India was determined to hold the post at all costs. The post remained surrounded for four months and was supplied by helicopters. According to scholar Taylor Fravel, the standoff marked the "apogee of tension" for China's leaders.
By the time the Sino-Indian War started on the 20 October 1962, the Indian post had been reinforced by a company of troops. The Chinese PLA bombarded it with heavy shelling and employed a battalion to attack the post. The Indians suffered 33 killed and several wounded, and the company commander and several others were taken prisoner. By the end of the war, China reached its 1960 claim line.
