During the Indo-Pakistani War of 1965, the Pakistani troops invaded the Chhamb-Jaurian sector of Indian-administered Kashmir as part of Operation Grand Slam, making significant gains and capturing Chumb.

The reason behind this plan was to deter Indians from attacking the crucial north–south line of communications passing via Gujrat.

On 9 December 1971, the first Pakistani troops entered the surrounding area around Chumb under the personal supervision of Maj General Iftikhar Khan Janjua.

A memorial of Major General Iftikhar Khan Janjua is located in Chumb where his helicopter crashed during the battle.

The members of the Chackmerry community in Chhamb are descendants of early Gujjar settlers who had arrived here from Rajauri in India.
