During his army career, he had commanded the Operation Blue Star under orders from Indira Gandhi to clear the Golden Temple shrine. Widely respected as a scholar warrior, he was regarded as one of the most promising generals of Independent India. He introduced a number of technology initiatives to the Indian Army.[3] He was also questioned for his role in recommending the Boforshowitzer in the Bofors scandal. As the Chief of the Army Staff, he planned and executed Operation Brasstacks, a major military exercise, along the Rajasthan border.
Sundarji was promoted to major general on 26 July 1974.[5] For the first time in the history of the Indian Army, an infantry officer became the general officer commanding of the elite 1st Armoured Division. He was chosen by General K. V. Krishna Rao to be part of a small team for reorganising the Indian Army, especially with regard to technology. He raised the Mechanised Infantry Regiment by amalgamating various battalions from the army's premier infantry regiments.
Operation Blue Star
He was promoted to lieutenant general on 5 February 1979.[6] In 1984, he led Operation Blue Star, intended to evict extremists who had occupied the Golden Temple in Amritsar. He later said "We went inside with humility in our hearts and prayers on our lips". According to his wife, Sundarji emerged a changed man after this operation.[7]
Chief of Army Staff
In 1986, he was promoted to general and appointed Chief of the Army Staff (COAS). After taking over as COAS, he wrote a letter to his soldiers warning of deteriorating standards, and the evil of sycophancy. His operation at Sumdorong Chu in 1986, known as Operation Falcon, was widely praised. The Chinese had occupied Sumdorong Chu, and Sundarji used the Indian Air Force's new airlift capability to land a brigade in Zimithang, north of Tawang. Indian forces took up positions on the Hathung La ridge, across the Namka Chu river, where India had faced a humiliating defeat in 1962. The Chinese responded with a counter-build-up and adopted a belligerent tone. Western diplomats predicted war, and some of Prime Minister Rajiv Gandhi's advisers blamed Sundarji's recklessness. But Sundarji stood by his steps, at one point telling a senior aide, "Please make alternate arrangements if you think you are not getting adequate professional advice." The confrontation petered out.
He was also involved in Operation Brasstacks, a large-scale mechanised artillery and war gaming effort in July 1986 near the Pakistan border, which led to similar Pakistani buildup. The situation was defused through diplomatic talks in February 1987.
In 1987, the Indian government forced Sri Lankan president to accept a ceasefire agreement with LTTE and the Indian Peace Keeping Force was sent to Jaffna to disarm the Liberation Tigers of Tamil Eelam (LTTE). However, the Indian Army had no experience in unconventional jungle warfare and took heavy casualties. Among the few successes was the bombing of the LTTE controlled jetties by the Indian Navy Marine Commandos, then known as the Indian Navy Special Commando Force. The Indian Peace Keeping Force force was withdrawn in 1990.
Nuclear policy
Sundarji was amongst the core team that created Indian nuclear policy. As a senior army general, he wrote the Indian Nuclear Doctrine along with Admiral R.H. Tahiliani. Post retirement, he was unhappy with the lack of response among politicians regarding nuclear security, and wrote the book Blind Men of Hindustan in 1993, which discussed nuclear strategy for India and compared India's nuclear policy to six blind men who misinterpret an elephant by touching parts of it.
Legacy
Sundarji was amongst the most far-sighted armoured corps commanders in the Indian Army.[8] Despite being commissioned in the infantry, he was a keen student and admirer of tank warfare. He pioneered various operational guidelines and challenged his commanders to push the machines and men to the limits. In various exercises, he is known to have ordered tanks full speed up sand dunes in the Thar Desert in 70 degree heat. Amongst other things, he designed the all black uniform of the Armoured Corps. He then went on to create the Mechanised Infantry Regiment. With emphasis on speed, technology and mobile weaponry, it is now an integral part of the Indian strike corps.
Sundarji can also be credited for shaping modern Indian Army thinking. In his stint as the commandant of the College of Combat (now Army War College, Mhow), he practically rewrote the war manual with emphasis on speed, decisive action, technology and armour. Sundarji was also one of the few to predict the total rout of the Iraqi forces in the Gulf War. Writing for India Today, he saw what superior air power and technology could do.
He also left behind a partially completed autobiography titled Of Some Consequence: A Soldier Remembers, of which he had completed 33 episodes out of a planned 105.
Personal life
Sundarji married Padma Sundarji when he was a major. They had two children, Pria and Vikram. In 1978, when he was serving as general officer commanding XXXIII Corps in the Eastern Command, she died of cancer at the Army Hospital, Delhi Cantonment. Later, he married for the second time. His second wife, Vani, wrote the introductory chapter of Sundarji's memoirs Of some consequence – A soldier remembers, which was published after his death.[9]
Death
In January 1998, Sundarji was diagnosed with motor neuron disease, from which he died on 8 February 1999 at the age of 70.[10]
