What was the Indo-China War of 1962?

The Sino-Indian War (also called the Indo-China War) was an armed conflict between India and China fought from 20 October to 20 November 1962. The war was fought along two fronts: in the North-East Frontier Agency (NEFA) (now Arunachal Pradesh) east of Bhutan, and in Aksai Chin (Ladakh) west of Nepal. Much of the combat took place at altitudes exceeding 4,000 metres (13,000 ft) in extremely harsh mountain conditions.

The conflict stemmed from unresolved border disputes inherited from the colonial era, particularly regarding the McMahon Line drawn at the Simla Convention (1914) between British India and Tibet, which China never accepted. Tensions escalated after the 1959 Tibetan uprising, when India granted asylum to the Dalai Lama. Border skirmishes increased through 1960-1962.

China launched a massive offensive on 20 October 1962 (during the Cuban Missile Crisis) and overwhelmed Indian forces in both sectors. China unilaterally declared a ceasefire on 20 November 1962 and withdrew to pre-war positions in NEFA, though it retained control of Aksai Chin. The war was a severe military and diplomatic shock for India, leading to major reforms in defence preparedness and a reassessment of Nehru's foreign policy.
