During and following the Indo-Pakistan war of 1965, the Dumchele area saw some action mainly in the form of the Indian and Chinese governments exchanging notes blaming each other for intruding into "their" territory. At Tsoskur, southeast of Dumchele, three Indian armed personnel were killed by PLA troops on 19 September 1965. Also in September 1965, according to the Chinese, India's border provocation at Dumchele was the worst provocation since 1962.
