Sardarilal Mathradas Nanda

After the partition of India, the Cauvery was assigned to India and she set sail for Bombay. The British officers embarked for England and Nanda was appointed Executive Officer of the ship. HMIS Kistna (U46) and Cauvery commanded by Commander Ram Dass Katari and Commander Reggie Sawhney respectively made two trips to the United Kingdom. This was because the cruiser HMS Achilles (70) was being purchased by India and renamed HMIS Delhi and the crew was to be transported.[12] In 1948, he was promoted to the acting rank of Lieutenant Commander and appointed first lieutenant of HMIS Delhi (1948) under the command of Captain H.N.S. Brown, with Commander Ram Dass Katari as his executive officer.[1] To train for this appointment, he was ordered to join the Mediterranean Fleet. He served on board the aircraft carrier HMS Triumph (R16) and subsequently on the cruiser HMS Newcastle (C76).[13]

HMIS Delhi was commissioned on 5 July 1948 by the High Commissioner of India to the United Kingdom V. K. Krishna Menon. On her way to India, she called at Portsmouth, Portland, Gibraltar and Malta. The Prime Minister of India Jawaharlal Nehru himself welcomed the ship at Bombay.[14] She went on a cruise round the coasts of India, calling at Karwar, Cochin, Trincomalee, Madras, Vizag, Calcutta, Port Blair, Colombo and Calicut before returning to Bombay.[15] In May 1949, she left on her Indian Ocean cruise. She called at Victoria, Seychelles, Port Louis in Mauritius, Dar es Salaam in Tanzania and Mombasa in Kenya. The cruise to the Indian Ocean republics and East Africa generated a tremendous amount of goodwill.[16][17]

On 30 June 1949, at the end of the goodwill mission, Nanda was promoted substantive lieutenant-commander and to the acting rank of Commander.[18] He was appointed director of personnel services (DPS) at Naval headquarters.[19] Nanda was promoted to substantive commander on 31 December 1950.[20] He served as the DPS for about two years. On 10 October 1951, he took command of the R class destroyer, INS Ranjit (1949).[21] The Ranjit was part of the 11th Destroyer Squadron commanded by Captain Ram Dass Katari. The other two ships in the squadron were INS Rajput (D141) and INS Rana (1942).[22] Nanda took the ship on a goodwill cruise to Singapore, Saigon, Jakarta and other ports in Indonesia like Bali. In Jakarta, he called on and was received by the first President of Indonesia, Sukarno.[23]

In early 1952, Princess Elizabeth and Prince Philip, Duke of Edinburgh set out for a tour of Australia and New Zealand by way of Kenya. The Rajput and the Ranjit were nominated to escort the HMY Britannia from Mombasa to Australia.[24] With the death of King George VI, this was cancelled. To commemorate the Coronation of Elizabeth II, a massive Coronation review of the fleet was held at Portsmouth. The flagship INS Delhi, commanded by Captain Adhar Kumar Chatterji, destroyer INS Ranjit, commanded by Nanda, and the frigate INS Tir (K256), commanded by Commander Nilakanta Krishnan, represented India at the review.[25] A naval armada consisting of ships from the Indian Navy, Royal Navy, Royal Australian Navy and the Royal New Zealand Navy sailed from Portsmouth to Gibraltar. The fleet carried out exercises along the way and was under the command of Lord Mountbatten. The Ranjit under Nanda acquitted itself well during these exercises. Subsequently, the Indian ships continued conducting exercises with the Mediterranean Fleet. They sailed from Gibraltar to Malta, the Greek islands and to Istanbul.[26]

Nanda took command of INS Jamuna (U21) on 31 August 1953 after returning to Bombay. He was also appointed Captain (F) 12th Frigate Squadron. On 15 February 1954, he was promoted to the acting rank of Captain and appointed CAPBRAX (captain naval barracks) and Commanding Officer of INS Angre. After a short stint, he was transferred back to Naval Headquarters as Chief of Personnel (COP) in September 1954. He was promoted to substantive captain on 31 December 1954.[27] He served as the COP for about two and a half years. In September 1956, he was promoted to Commodore 2nd Class.[28]

In December 1956, he was appointed the commissioning commanding officer of INS Mysore (1957). The Crown Colony-class cruiser HMS Nigeria (60) was being refitted and modernised in Birkenhead, Liverpool to be commissioned as the Mysore. He spent a few months in UK preparing his crew. INS Mysore was commissioned on 29 August 1957 by the High Commissioner of India to the United Kingdom Vijaya Lakshmi Pandit. Nanda took the ship to the Mediterranean and subsequently paid an official visit to the port of Split in Socialist Federal Republic of Yugoslavia. He called on President Josip Broz Tito at his home in the Brioni Islands.

Returning to India, Nanda and the Mysore were welcomed by the entire Indian Fleet, commanded by the first Indian Fleet Commander Rear Admiral Ram Dass Katari. Katari's flag was transferred from INS Delhi to INS Mysore, thus becoming the new flagship of the Indian Fleet.[29] The Prime Minister Jawaharlal Nehru visited the ship at Bombay and hosted a dinner on board with the Governor of Maharashtra Ali Yavar Jung, the Minister of Defence V. K. Krishna Menon, Chief Minister of Maharashtra Vasantrao Naik being present.[30] After visiting the ports in India, Nanda took the ship to a goodwill visit to China and Japan in the summer of 1958. She called at Singapore, Hong Kong, Shanghai and Yokohama. On the return passage, she called at Haiphong. Before leaving India for the goodwill visit, Nanda had been selected to attend the Imperial Defence College (IDC) and was to embark for the UK after completing the visit. Instead he was informed after departing from Haiphong that his deputation to IDC stood cancelled.[31]

Personally selected by the Defence Minister V K Krishna Menon, Nanda took over as the Director General Naval Dockyard Expansion Scheme (DG-NDES) on 1 October 1958. He undertook a major expansion of the dockyard.[32] He extended the dimensions of the cruiser dock to accommodate the aircraft carrier HMS Hercules (R49) being acquired from the UK. This resulted in tremendous advantage for the Indian Navy. For distinguished service during his tenure as DG-NDES, Nanda was awarded the Ati Vishisht Seva Medal in 1961.[33] In June 1960, he was appointed Officer on Special Duty (OSD) at Naval HQ.[34] Nanda was selected to attend the Imperial Defence College and embarked for the UK in early 1961. After completing the year-long course, he returned to India and was appointed Chief of Materiel (COM) in February 1962.[35]

In May 1962, Nanda was promoted to the acting rank of Rear Admiral and appointed Deputy Chief of Naval Staff.[36][37] As DCNS, he was instrumental in obtaining permission and clearance from the Government of India (GOI) for the naval development of the port at Goa, which was recently annexed. Given the difficulty India had in negotiating the purchase of INS Vikrant (R11) from the UK, Nanda supported the acquisition of equipment from the Soviet Union. Promoted to substantive rear-admiral on 16 June 1964,[38] Nanda was appointed Managing Director of Mazagon Dock Limited in December 1964. He undertook preparations for the construction of Nilgiri class frigates, the first major naval vessels to be constructed in India. After a 18-month tenure, he handed over charge to Rear Adm Benjamin Abraham Samson in May 1966. Shortly afterwards, in October, the keel of the first frigate INS Nilgiri (F33) was laid.[39] For his distinguished service as MD of Mazagon Dock, he was awarded the Param Vishisht Seva Medal in January 1966.[40]

On 1 June 1966, Nanda took command of the Indian Fleet as the Flag Officer Commanding Indian Fleet at Bombay.[41] Flying his flag, the fleet visited the Persian Gulf in April 1967. The INS Vikrant (R11) visited Bahrain and Kuwait, while her escorts INS Trishul (F143) and INS Talwar (F140) visited Abadan and Basra. The fleet tanker INS Deepak joined the fleet under Nanda.[42]

Nanda took over as Flag Officer Bombay (FOB) on 1 February 1968. In March 1968, the reorganisation of the Navy took place. Posts were upgraded and created at the Naval HQ as well as the naval commands. Nanda was promoted to the rank of Vice Admiral and became the first Flag Officer Commanding-in-Chief (FOC-in-C) Western Naval Command.[43][44][45] Nanda organised the Navy Week in December 1969 which culminated with the review of the Indian Naval Fleet by President V. V. Giri. A successful event, it raised the navy's profile in Bombay. The Navy Week involved the businessmen, industrialists, Bollywood stars and the society at large. Funds were raised and a Sailors' home and an Officers' Mess was also built.[46]

In November 1969, the GOI decided to appoint Nanda as the next CNS in succession to Adm Adhar Kumar Chatterji.[47] On 1 March 1970, Nanda took command as the 8th Chief of the Naval Staff of the Indian Navy.[48] The 1962 Sino-Indian War was largely fought over the Himalayas and the Navy did not have a major role. During the Indo-Pakistani War of 1965, the Navy was ordered to stay within Indian waters. When the Pakistan Navy bombarded Dwarka, Nanda recognised the need to raise the Navy's profile and capabilities. He was determined to change the mindset of the service from defence to attack.[49] He got the opportunity to demonstrate this capability the following year during the war with Pakistan.

The Indo-Pakistani War of 1971 was sparked by the Bangladesh Liberation war, a conflict between the traditionally dominant West Pakistanis and the majority East Pakistanis. In 1970, East Pakistanis demanded autonomy for the state, but the Pakistani government failed to satisfy these demands and, in early 1971, a demand for secession took root in East Pakistan. In March, the Pakistan Armed Forces launched a fierce campaign to curb the secessionists, the latter including soldiers and police from East Pakistan. Thousands of East Pakistanis died, and nearly ten million refugees fled to West Bengal, an adjacent Indian state. In April, India decided to assist in the formation of the new nation of Bangladesh.[50]

Nanda was instrumental in framing India's Naval strategy during the war. He feigned a defensive deployment southeast towards the Andaman Islands, instead moving his Eastern fleet northwards into the Bay of Bengal and enforcing a naval blockade against East Pakistan.

His strategy against West Pakistan was to strike hard against Pakistan's main port of Karachi.[1] He is recognized as the mastermind behind Operation Trident and Operation Python.[51] The plan for the operations included towing the limited-range Vidyut class missile boats, primarily designed for coastal defence, to about 250 nautical miles (460 km) south of Karachi during the day, out of range of the Pakistan Air Force aircraft.[52] The missile boats then closed in on Karachi port at night and attacked naval targets as well as the oil tank farm at Keamari. Operation Trident was successfully executed on 4 December 1971, sinking the Pakistan Navy destroyer PNS Khaibar, minesweeper PNS Muhafiz, an ammunition carrying ship MV Venus Challenger and irreparably damaging another destroyer PNS Shah Jahan as well as destroying numerous oil storage tanks. Operation Python was again successfully carried out on 8 December 1971.

On the Eastern front, Nanda made the decision to deploy the aircraft carrier INS Vikrant into the shallower waters of the Gulf of Bengal off Dhaka, to prevent the risk of a submarine attack. When concerns were raised about Vikrant's boilers being cracked, he took personal responsibility for the risk of a boiler explosion and catapult failure on the carrier. His gambit paid off, as Vikrant was able to successfully enforce the blockade of East Pakistan without any such damage to the carrier.

The war lasted less than a fortnight and saw more than 90,000 Pakistani soldiers taken prisoner. It ended with the unconditional surrender of Pakistan's eastern half and resulted in the birth of Bangladesh as a new nation.[53] In addition to the POWs, Pakistan suffered 6,000 casualties against India's 2,000.[54] The success of the naval blockades on two fronts is considered one of the primary factors in India's overwhelming victory during the war. For his services to the nation, he was awarded the Padma Vibhushan in January 1972.[1][55][56]
