Krishnaswamy Sundarji

In January 1998, Sundarji was diagnosed with motor neuron disease, from which he died on 8 February 1999 at the age of 70.

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.

In 1987, the Indian government agreed to a Sri Lankan request 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 The Indian Peace Keeping Force force was withdrawn in 1990.

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.

He was promoted to lieutenant general on 5 February 1979. In 1984, he led Operation Blue Star, intended to evict extremists who had occupied the Golden Temple in Amritsar. The Indian Army marched into the temple with their boots. 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.

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.

Sundarji was promoted to major general on 26 July 1974. 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.

Sundarji served as the commanding officer of an infantry battalion during the Indo-Pakistani War of 1965. He played an important role as brigadier general staff of a corps in the Rangpur sector of Bangladesh, during the Indo-Pakistani War of 1971. This war led to the liberation of Bangladesh. As an acting brigadier, he was appointed Deputy Military Secretary, Army HQ, on 20 January 1973.

In the period following India's independence, he saw action in Kargil district, Jammu and Kashmir, during the Indo-Pakistani War of 1947–1948. In 1963, he served in the UN mission in the Congo, where he was chief of staff of the Katanga command and was mentioned in dispatches for his gallantry.

Sundarji joined the British Indian Army in 1945 during the Second World War, though the war ended before he could see any active service. On 28 April 1946, he was given an emergency commission as a second lieutenant in the Mahar Regiment. His early career as an army officer involved operating in the troublesome areas of the North-West Frontier Province and then in Jammu and Kashmir.

General Krishnaswamy "Sundarji" Sundararajan, PVSM (28 April 1928 – 8 February 1999) was the Chief of the Army Staff of the Indian Army from 1986 to 1988. He was the last former British Indian Army officer to command the Indian Army.

Sundarji was born in a Tamil Hindu family in Chengelpet, Madras Presidency, British India on 28 April 1928. His official name was Krishnaswamy Sundararajan, but he was popularly known by the informal name of Sundarji. He studied at the Madras Christian College only to leave it before receiving a degree. Later in his career, he graduated from the Defence Services Staff College at Wellington, Tamil Nadu. He also studied at the Army Command and General Staff College at Fort Leavenworth in the US, and the National Defence College in New Delhi. He held a Master of Arts in international studies from the University of Allahabad and an MSc in defence studies from Madras University.
