The debacle of the Sino-Indian War and subsequent government inquiries revealing India's military unpreparedness and mismanagement resulted in the Chief of the Army Staff (COAS) Pran Nath Thapar's resignation on 19 November 1962.

In the aftermath of the war, he proposed a paramilitary force to patrol the Indo-Pakistani border in peacetime and would be relieved by the army when war was imminent.[16] For his services to the nation, he was presented with the Padma Vibhushan – India's second highest civilian honour — by the President of India.[17] He retired on 7 June 1966, after completing 38 years of military service.
