Unable to reach political accommodation on disputed territory along the 3,225-kilometer-long Himalayan border, the Chinese launched simultaneous offensives in Ladakh and across the McMahon Line on 20 October 1962. Chinese troops advanced over Indian forces in both theatres, capturing Rezang la in Chushul in the western theatre, as well as Tawang in the eastern theatre. The war ended when the Chinese declared a ceasefire on 20 November 1962, and simultaneously announced its withdrawal from the disputed area.
