First Kashmir War (1947)
Immediately after independence, tensions between India and Pakistan began to boil over, and the first of three full-scale wars between the two nations broke out over the then princely state of Kashmir. The Maharaja of Kashmir wanted to have a standstill position. Since Kashmir was a Muslim majority state, Pakistan wanted to make Kashmir a Pakistani territory. As a result, Pakistan invaded Kashmir on 22 October 1947, causing Maharaja Hari Singh to look to India, specifically to Lord Mountbatten of Burma, the governor general, for help. He signed the Instrument of Accession to India on 26 October 1947. Indian troops were airlifted to Srinagar from 27 October dawn onwards. This contingent included General Thimayya who distinguished himself in the operation and in the years that followed became a Chief of the Indian Army. An intense war was waged across the state and former comrades found themselves fighting each other. Pakistan suffered significant losses. Its forces were stopped on the line formed which is now called LOC (Line of Control). An uneasy UN sponsored peace returned by the end of 1948 with Indian and Pakistani soldiers facing each other directly on the Line of Control, which has since divided Indian-held Kashmir from Pakistan-held Kashmir. A number of UN resolutions (38–47) were passed calling for a plebiscite to be held in Kashmir to determine accession to India or Pakistan only after Pakistan withdrew its army from Kashmir. A precondition to the resolution was for Pakistan and India to return to a state of "as was" prior to the conflict. Pakistan would withdraw all tribesmen and Pakistani nationals brought in to fight in Kashmir. With Pakistan refusing to pull back there could be no further dialogue on fulfilling the UN resolution. Tensions between India and Pakistan, largely over Kashmir, have never been entirely eliminated.
Annexation of Hyderabad (1948)
After the partition of India, the State of Hyderabad, a princely state under the rule of a Nizam, chose to remain independent. The Nizam, refused to accede his state to the Union of India. The following stand-off between the Government of India and the Nizam ended on 12 September 1948 when India's then deputy Prime Minister Sardar Vallabhbhai Patel ordered Indian troops to secure the state. During five days of fighting, the Indian Army, backed by an Indian Air Force squadron of Hawker Tempest aircraft, routed the Hyderabad State forces. Five Indian Army infantry battalions and one armoured squadron were engaged in the operation. The following day, the State of Hyderabad was proclaimed as a part of the Union of India. Major General Joyanto Nath Chaudhuri, who led the Operation Polo and accepted the surrender of the Nizam's forces on 18 September 1948, was appointed the military governor of Hyderabad (1948–1949) to restore law and order.
Medical assistance during Korean War (1950–1953)
During the Korean War, India sent the 60th Indian (Parachute) Field Ambulance unit to aid the UN troops fighting against the Chinese and North Korean invasion of South Korea, though they decided against sending combat forces. The 60th PFA was included in the 1st Commonwealth Division In the aftermath of the war, an Indian infantry brigade formed the Custodian Force of India as some of the soldiers were also sent to Korea as part of the Neutral Nations Repatriation Committee to assist in the exchange of prisoners of war. The NNRC was commanded by Lt Gen KS Thimayya. Annexation of Goa, Daman and Diu (1961) Even though the British and French vacated all their colonial possessions in the Indian subcontinent, Portugal refused to relinquish control of its Indian colonies of Goa, Daman and Diu. After repeated attempts by India to negotiate with Portugal for the territory were spurned by Portuguese prime minister and dictator, António de Oliveira Salazar, India launched Operation Vijay on 12 December 1961 to take Goa from the Portuguese. A small contingent of its troops entered Goa, Daman, and Diu to capture and secure the territory. After a brief conflict, in which 31 Portuguese soldiers were killed, the Portuguese Navy frigate NRP Afonso de Albuquerque destroyed, and over 3,000 Portuguese captured, Portuguese General Manuel António Vassalo e Silva surrendered to Maj Gen KP Candeth (Kunhiraman Palat Kandoth) of the Indian Army, after twenty-six hours. Goa, Daman and Diu became a part of the Republic of India. Sino-Indian War (1962)
The cause of this war was a dispute over the sovereignty of the widely separated Aksai Chin and Arunachal Pradesh border regions. Aksai Chin, claimed by India to belong to Kashmir, and by China to be part of Xinjiang, contains an important road link that connects the Chinese regions of Tibet and Xinjiang. China's construction of this road was one of the triggers of the conflict.
Small-scale clashes between Indian and Chinese forces broke out as India insisted on the disputed McMahon Line being regarded as the international border between the two countries. Chinese troops claimed not to have retaliated to the cross-border firing by Indian troops, despite sustaining losses. China's suspicion of India's involvement in Tibet created more rifts between the two countries.
In 1962, the Indian Army was ordered to move to the Thag La ridge located near the border between Bhutan and Arunachal Pradesh and about three miles (5 km) north of the disputed McMahon Line. Meanwhile, Chinese troops had also made incursions into Indian-held territory, and tensions between the two reached a new high when Indian forces discovered a road constructed by China in Aksai Chin. After a series of failed negotiations, the People's Liberation Army attacked Indian Army positions at the Thag La ridge. This move by China caught India by surprise and by 12 October, Nehru gave orders for the Chinese to be expelled from Aksai Chin. However, poor co-ordination among various divisions of the Indian Army, and the late decision to mobilise the Indian Air Force in vast numbers, gave China a crucial tactical and strategic advantage over India. On 20 October, Chinese soldiers attacked India in both the North-West and North-Eastern parts of the border and captured vast portions of Aksai Chin and Arunachal Pradesh.
As the fighting moved beyond disputed territories, China called on the Indian government to negotiate, however India remained determined to regain lost territory. With no peaceful agreement in sight, China unilaterally withdrew its forces from Arunachal Pradesh. The reasons for the withdrawal are disputed with India claiming various logistical problems for China and diplomatic support from the United States, while China stated that it still held territory it had staked diplomatic claim over. The dividing line between the Indian and Chinese forces was named the Line of Actual Control.
The poor decisions made by India's military commanders and, its political leadership, raised several questions. The Henderson-Brooks & Bhagat committee was soon set up by the Government of India to determine the causes of the poor performance of the Indian Army. Its report criticised the decision not to allow the Indian Air Force to target Chinese transport lines out of fear of a Chinese aerial counter-attack on Indian civilian areas. Much of the blame was also targeted at the incompetence of then-Defence Minister, Krishna Menon who resigned from his post soon after the war ended. Despite frequent calls for its release, the Henderson-Brooks report still remains classified. Neville Maxwell has written an account of the war. Indo-Pakistani War of 1965
A second confrontation with Pakistan took place in 1965. Although the war is described as inconclusive, India had the better of the war and was a clear winner in tactical and strategic terms. Pakistani President Ayub Khan launched Operation Gibraltar in August 1965, during which several Pakistani paramilitary troops infiltrated into Indian-administered Kashmir and attempt to ignite an anti-India agitation in Jammu and Kashmir. Pakistani leaders believed that India, which was still recovering from the disastrous Sino-Indian War, would be unable to deal with a military thrust and a Kashmiri rebellion. India reacted swiftly and launched a counter offensive on Pakistan. Pakistan launched Operation Grand Slam in reply on 1 September, invading India's Chamb-Jaurian sector. In retaliation, the Indian Army launched a major offensive throughout its border with Pakistan, with Lahore as its prime target.
Initially, the Indian Army met with considerable success in the northern sector. After launching prolonged artillery barrages against Pakistan, India was able to capture three important mountain positions in Kashmir. By 9 September, the Indian Army had made considerable in-roads into Pakistan. India had its largest haul of Pakistani tanks when the offensive of Pakistan's 1st Armoured Division was blunted at the Battle of Asal Uttar, which took place on 10 September near Khemkaran. The biggest tank battle of the war came in the form of the Battle of Chawinda, the largest tank battle in history after World War II. Pakistan's defeat at the Battle of Asal Uttar hastened the end of the conflict.
At the time of ceasefire declaration, per neutral sources, India reported casualties of about 3,000. On the other hand, it was estimated that more than 3,800 Pakistani soldiers were killed in the battle. About 200-300 Pakistani tanks were either destroyed or captured by India. India lost a total of 150-190 tanks during the conflict. The decision to return to pre-war positions, following the Tashkent Declaration, caused an outcry among the polity[who?] in New Delhi. It was widely believed that India's decision to accept the ceasefire was due to political factors, and not military, since it was facing considerable pressure from the United States and the UN to stop hostilities.
1967 Sino-Indian Conflict The 1967 Sino-Indian skirmish, also known as the Cho La incident, was a military conflict between Indian troops and members of the Chinese People's Liberation Armywho had infiltrated on 1 October 1967 in Sikkim, then a protectorate of India. On 10 October, both sides clashed again. Defence Minister Sardar Swaran Singh assured the Indian people that the government was taking care of developments along the border. In the aftermath of the conflict Indian losses were 88 killed, and 163 wounded, while Chinese casualties were 300 killed and 450 wounded in Nathula, and 40 in Chola. The Chinese Army left Sikkim after being defeated by Indian troops. Operation against the Naxalites during 1971 Under the supervision of Indira Gandhi during the president's rule in 1971, the Indian Army and the Indian police launched Operation Steeplechase, a gigantic "counter-insurgency" operation against the Naxalites, which resulted in the death of hundreds of Naxalites and the imprisonment of more than 20,000 suspects and cadres including senior leaders. The army was also assisted by a brigade of para commandos and the Indian paramilitary. The operation was organised in October 1969, and Lieutenant General J.F.R. Jacob was enjoined by Govind Narain, the home secretary of India, that "there should be no publicity and no records" and Jacob's request to be presented with written orders was also repudiated by Sam Manekshaw. Bangladesh Liberation War of 1971
An independence movement broke out in East Pakistan which was crushed by Pakistani forces. Due to large-scale atrocitiesagainst them, thousands of Bengalis took refuge in neighbouring India causing a major refugee crisis there. In early 1971, India declared its full-support for the Bengali rebels, known as Mukti Bahini, and Indian agents were extensively involved in covert operations to aid them.
On 20 November 1971, the Indian Army moved the 14 Punjab Battalion 45 Cavalry into Garibpur, a strategically important town near India's border with East Pakistan, and successfully captured it. The following day, more clashes took place between Indian and Pakistani forces. Wary of India's growing involvement in the Bengali rebellion, the Pakistan Air Force(PAF) launched a preemptive strike on 10 Indian air bases at: Srinagar, Jammu, Pathankot, Amritsar, Agra, Adampur, Jodhpur, Jaisalmer, Uttarlai and Sirsa at 17:45 hours on 3 December. However, this aerial offensive failed to accomplish its stated objectives, and gave India an excuse to declare a full-scale war against Pakistan the same day. By midnight, the Indian Army, accompanied by the Indian Air Force, launched a major three-pronged assault into East Pakistan. The Indian Army won several battles on the eastern front including the decisive battle of Hilli, which was the only front where the Pakistani Army was able to build up considerable resistance. The operation also included a battalion-level airborne operation on Tangail, which resulted in the capitulation of all resistance within five days. India's massive early gains were attributed largely to the speed and flexibility with which Indian armoured divisions moved across East Pakistan.
Pakistan launched a counter-attack against India on the western front. On 4 December 1971, the A company of the 23rd Battalion of India's Punjab Regiment detected and intercepted the movement of the 51st Infantry Brigade of the Pakistani Army near Ramgarh, Rajasthan. The battle of Longewala ensued during which the A company, though being outnumbered, thwarted the Pakistani advance until the Indian Air Force directed its fighters to engage the Pakistani tanks. By the time the battle had ended, 38 Pakistani tanks and 100 armoured vehicles were either destroyed or abandoned. About 200 Pakistani troops were killed in action during the battle while two Indian soldiers lost their lives. Pakistan suffered another major defeat on the western front during the battle of Basantar which was fought from 4 December to the 16th. By the end of the battle, about 66 Pakistani tanks were destroyed and 40 more were captured. In return, Pakistani forces were able to destroy only 11 Indian tanks. None of the many Pakistani offensives on the western front materialised. By 16 December, Pakistan had lost sizeable territory on both the eastern and western fronts.
Under the command of Lt. General J.S. Arora, the three corps of the Indian Army, which had invaded East Pakistan, entered Dhaka and forced Pakistani forces to surrender on 16 December 1971, one day after the conclusion of the battle of Basantar. After Pakistan's Lt General A A K Niazi signed the Instrument of Surrender, India took more than 90,000 Pakistani prisoners of war. By the time of the signing, 11,000 Pakistani soldiers were killed-in-action while India suffered 3,500 battle-related deaths. In addition, Pakistan lost 220 tanks during the battle compared to India's 69.
In 1972, the Simla Agreement was signed between the two countries and tensions simmered. However, there were occasional spurts in diplomatic tensions which culminated in increased military vigilance on both sides.
Siachen conflict (1984)
The Siachen Glacier, though a part of the Kashmir region, was not officially demarcated on maps prepared and exchanged between the two sides in 1947. As a consequence, prior to the 1980s, neither India nor Pakistan maintained any permanent military presence in the region. However, Pakistan began conducting and allowing a series of mountaineering expeditions to the glacier beginning in the 1950s. By the early 1980s, the Government of Pakistan was granting special expedition permits to mountaineers and United States Army maps deliberately showed Siachen as a part of Pakistan. This practice gave rise to the contemporary meaning of the term oropolitics.
India, possibly irked by these developments, launched Operation Meghdoot in April 1984. An entire battalion of the Kumaon Regiment was airlifted to the glacier. Pakistani forces responded quickly and clashes between the two followed. The Indian Army secured the strategic Sia Laand Bilafond La mountain passes, and by 1985 more than 1,000 square miles (2,600 km2) of territory 'claimed' by Pakistan was under Indian control. The Indian Army continues to control all the Siachen Glacier and its tributary glaciers. Pakistan made several unsuccessful attempts to regain control over Siachen. In late 1987, Pakistan mobilised about 8,000 troops and garrisoned them near Khapalu, aiming to capture Bilafond La. However, they were repulsed by Indian Army personnel guarding Bilafond. During the battle, about 23 Indian soldiers lost their lives, while more than 150 Pakistani troops perished. Further unsuccessful attempts to reclaim positions were launched by Pakistan in 1990, 1995, 1996 and 1999, most notably in Kargil that year.
India continues to maintain a strong military presence in the region, despite extremely inhospitable conditions. The conflict over Siachen is regularly cited as an example of mountain warfare. The highest peak in the Siachen glacier region, Saltoro Kangri, could be viewed as strategically important for India because of its immense altitude which could enable the Indian forces to monitor some Pakistani or Chinese movements in the immediate area. Maintaining control over Siachen poses several logistical challenges for the Indian Army. Several infrastructure projects were constructed in the region, including a helipad at 21,000 feet (6,400 m) above the sea level. In 2004, the Indian Army was spending an estimated US$2 million a month to support its personnel stationed in the region. Counter-insurgency activities The Indian Army has played a crucial role in the past, fighting insurgents and terrorists within the nation. The army launched Operation Blue Star and Operation Woodrosein the 1980s to combat Sikh insurgents. The army, along with some paramilitary forces, has the prime responsibility of maintaining law and order in the troubled Jammu and Kashmir region, led specifically by the Northern Command. The Indian Army also sent a contingent to Sri Lanka in 1987 as a part of the Indian Peace Keeping Force. Allied with the work of the Northern Command and its peace time activities is "North Tech Symposium", an annual event, with the aim of providing a viable platform for knowledge diffusion on relevant, contemporary military technologies available as commercial off the shelf (COTS) worldwide. The Indian Army also successfully conducted Operation Golden Bird in 1995 for counter-insurgency in northeast India.
Kargil war (1999)
In 1998, India carried out nuclear tests and a few days later, Pakistan responded with more nuclear tests giving both countries nuclear deterrence capability, although India had tested one hydrogen bomb which Pakistan lacked. Diplomatic tensions eased after the Lahore Summit was held in 1999. However, the sense of optimism was short-lived since in mid-1999 Pakistani paramilitary forces and Kashmiri insurgents captured the deserted, but strategic, Himalayan heights in the Kargil district of India. These had been vacated by the Indian army during the onset of the inhospitable winter and were supposed to be reoccupied in spring. The regular Pakistani troops who took control of these areas received important support, both in the form of arms and supplies, from Pakistan. Some of the heights under their control, which also included the Tiger Hill, overlooked the vital Srinagar-Leh Highway (NH 1A), Batalik and Dras.
Once the scale of the Pakistani incursion was realised, the Indian Army quickly mobilised about 200,000 troops and Operation Vijay was launched. However, since the heights were under Pakistani control, India was at a clear strategic disadvantage. From their observation posts, the Pakistani forces had a clear line-of-sight to lay down indirect artillery fire on NH 1A, inflicting heavy casualties on the Indians. This was a serious problem for the Indian Army as the highway was its main logistical and supply route. Thus, the Indian Army's first priority was to recapture peaks that were in the immediate vicinity of NH 1A. This resulted in Indian troops first targeting the Tiger Hill and Tololing complex in Dras. This was soon followed by more attacks on the Batalik-Turtok sub-sector which provided access to Siachen Glacier. Point 4590, which had the nearest view of the NH 1A, was successfully recaptured by Indian forces on 14 June.
Though most of the posts in the vicinity of the highway were cleared by mid-June, some parts of it near Drass witnessed sporadic shelling until the end of the war. Once the NH 1A area was cleared, the Indian Army turned to driving the invading force back across the Line of Control. The Battle of Tololing, among other assaults, slowly tilted the combat in India's favour. Nevertheless, some posts put up a stiff resistance, including Tiger Hill (Point 5140) that fell only later in the war. As the operation was fully under way, about 250 artillery guns were brought in to clear the infiltrators in the posts that were in the line-of-sight. At many vital points, neither artillery nor air power could dislodge the outposts manned by the Pakistan soldiers, who were out of visible range. The Indian Army mounted some direct frontal ground assaults which were slow and took a heavy toll given the steep ascent that had to be made on peaks as high as 18,000 feet (5,500 m). Two months into the conflict, Indian troops had slowly retaken most of the ridges they had lost; according to official count, an estimated 75%–80% of the intruded area, and nearly all high ground, was back under Indian control.
Following the Washington accord on 4 July, where Sharif agreed to withdraw Pakistani troops, most of the fighting came to a gradual halt, but some Pakistani forces remained in positions on the Indian side of the LOC. In addition, the United Jihad Council(an umbrella for all extremist groups) rejected Pakistan's plan for a climb-down, instead deciding to fight on. The Indian Army launched its final attacks in the last week of July; as soon as the Drass sub-sector had been cleared of Pakistani forces, the fighting ceased on 26 July. The day has since been marked as Kargil Vijay Diwas (Kargil Victory Day) in India. By the end of the war, India had resumed control of all the territory south and east of the Line of Control, as was established in July 1972 per the Shimla Accord. By the time all hostilities had ended, the number of Indian soldiers killed during the conflict stood at 527, while more than 700 regular members of the Pakistani Army were killed. The number of Islamist fighters, also known as Mujahideen, killed by Indian Armed Forces during the conflict stood at about 3,000.
