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 at 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.
