Indo-Pakistani War of 1965

Indo-Pakistani War of 1965

The Indo-Pakistani War of 1965 was a culmination of skirmishes that took place between April 1965 and September 1965 between India and Pakistan. This conflict became known as the Second Kashmir War fought by India and Pakistan over the disputed region of Kashmir, the first having been fought in 1947. The war began following Pakistan's Operation Gibraltar, which was designed to infiltrate forces into Jammu and Kashmir to precipitate an insurgency against rule by India.^[6] The five-week war caused thousands of casualties on both sides. It ended in a United Nations (UN) mandated ceasefire and the subsequent issuance of the Tashkent Declaration.^[1]

Much of the war was fought by the countries' land forces in Kashmir and along the International Border between India and Pakistan. This war saw the largest amassing of troops in Kashmir since the Partition of British India in 1947, a number that was overshadowed only during the 2001–2002 military standoff between India and Pakistan. Most of the battles were fought by opposing infantry and armored units, with substantial backing from air forces, and naval operations. Many details of this war, like those of other Indo-Pakistani Wars, remain unclear.^[1]

On August 5, 1965 between 26,000 and 33,000 Pakistani soldiers crossed the Line of Control dressed as Kashmiri locals headed for various areas within Kashmir. Indian forces, tipped off by the local populace, crossed the cease fire line on August 15.^[9]

nitially, the Indian Army met with considerable success, capturing three important mountain positions after a prolonged artillery barrage. By the end of August, however, both sides had relative progress; Pakistan had made progress in areas such as Tithwal, Uri and Punch and India had captured the Haji Pir Pass, eight kilometers into Pakistan-occupied Kashmir. On September 1, 1965, Pakistan launched a counterattack, called Operation Grand Slam, with the objective to capture the vital town of Akhnoor in Jammu, which would sever communications and cut off supply routes to Indian troops. Attacking with an overwhelming ratio of troops and technically superior tanks, Pakistan made gains against Indian forces, who were caught unprepared and suffered heavy losses. India responded by calling in its air force to blunt the Pakistani attack. The next day, Pakistan retaliated, its air force attacked Indian forces and air bases in both Kashmir and Punjab. India's decision to open up the theater of attack into Pakistani Punjab forced the Pakistani army to relocate troops engaged in the operation to defend Punjab. Operation Grand Slam therefore failed, as the Pakistan Army was unable to capture Akhnoor; it became one of the turning points in the war when India decided to relieve pressure on its troops in  Kashmir by attacking Pakistan further south.

India crossed the International Border on the Western front on September 6, marking an official beginning of the war.^[11] On September 6, the 15th Infantry Division of the Indian Army, under World War II veteran Major General Prasad, battled a massive counterattack by Pakistan near the west bank of the Ichogil Canal (BRB Canal), which was a de facto border of India and Pakistan. The General's entourage itself was ambushed and he was forced to flee his vehicle. A second, this time successful, attempt to cross the Ichhogil Canal was made over the bridge in the village of Barki, just east of Lahore. These developments brought the Indian Army within the range of Lahore International Airport. As a result, the United States requested a temporary ceasefire to allow it to evacuate its citizens in Lahore. However, the Pakistani counter attack took Khem Karan from Indian forces which tried to divert the attention of Pakistanis from Khem Karan by an attack on Bedian and the adjacent villages.


The thrust against Lahore consisted of the 1st Infantry Division supported by the three tank regiments of the 2nd Independent Armoured Brigade; they quickly advanced across the border, reaching the Ichhogil (BRB) Canal by 6 September. The Pakistani Army held the bridges over the canal or blew up those it could not hold, effectively stalling any further advance by the Indians on Lahore. One unit of the Indian Jat Regiment, 3 Jat, had also crossed the Ichogil canal and captured^[12] the town of Batapore (Jallo Mur to Pakistan) on the west side of the canal. The same day, a counter offensive consisting of an armored division and infantry division supported by Pakistan Air Force Sabres forced the Indian 15th Division to withdraw to its starting point. Although 3 Jat suffered minimal casualties, the bulk of the damage being taken by ammunition and stores vehicles, the higher commanders had no information of 3 Jat's capture of Batapore and misleading information led to the command to withdraw from Batapore and Dograi to Ghosal-Dial. This move brought extreme disappointment^[13] to Lt-Col Desmond Hayde, CO of 3 Jat. Dograi was eventually recaptured by 3 Jat on 21 September, for the second time but after a much harder battle due to Pakistani reinforcements.

 On September 8, 1965, a company of 5 Maratha Light Infantry was sent to reinforce a Rajasthan Armed Constabulary (RAC) post at Munabao — a strategic hamlet about 250 kilometres from Jodhpur. Their brief was simple. To hold the post and to keep Pakistan's infantry battalions from overrunning the post at bay. But at Maratha Hill (in Munabao) - as the post has now been christened — the Indian company could barely manage to thwart the intense attack for 24 hours. A company of 3 Guards with 954 heavy mortar battery ordered to reinforce the RAC post at Munabao could never reach. The Pakistani Air Force had strafed the entire area, and also hit a railway train coming from Barmer with reinforcements near Gadra road railway station. On September 10, Munabao fell into Pakistani hands, and efforts to capture the strategic point did not succeed ^[16].
On the days following September 9, both nations' premiere formations were routed in unequal battles. India's 1st Armoured Division, labeled the "pride of the Indian Army", launched an offensive towards Sialkot. The Division divided itself into two prongs, was forced back by the Pakistani 6th Armoured Division at Chawinda and was forced to withdraw after suffering heavy losses of nearly 100 tanks. The Pakistanis followed up their success by launching Operation Windup, which forced the Indians back farther. Similarly, Pakistan's pride, the 1st Armoured Division, pushed an offensive towards Khem Karan, with the intent to capture Amritsar (a major city in Punjab, India) and the bridge on River Beas to Jalandhar.

The Pakistani 1st Armored Division never made it past Khem Karan, however, and by the end of September 10 lay disintegrated by the defences of the Indian 4th Mountain Division at what is now known as the Battle of Asal Uttar (lit. meaning – "Real Answer", or more appropriate English equivalent – "Fitting Response"). The area became known as 'Patton Nagar' (Patton Town), because of the large number of US-made Pakistani Patton tanks. Approximately 97 Pakistani tanks were destroyed or abandoned, with only 32 Indian tanks destroyed or damaged. The Pakistani 1st Armoured Division less 5th Armoured Brigade was next sent to Sialkot sector behind Pakistani 6th Armoured Division where it didn't see action as 6th Armoured Division was already in process of routing Indian 1st Armoured Division which was superior to it in strength.
The war was heading for a stalemate, with both nations holding territory of the other. The Indian army suffered 3,000 battlefield deaths, while Pakistan suffered 3,800. The Indian army was in possession of 710 mile² (1,800 km²) of Pakistani territory and the Pakistan army held 210 mile² (550 km²) of Indian territory. The territory occupied by India was mainly in the fertile Sialkot, Lahore and Kashmir sectors,^[17] while Pakistani land gains were primarily south in deserts opposite to Sindh and in Chumb sector near Kashmir in north.^[18]

Aerial warfare

Main article: Aerial warfare in 1965 India Pakistan War

Further information: Indian Air Force#Second Kashmir War 1965 and Pakistan Air Force#Indo-Pakistani War of 1965

he war saw aircraft of the Indian Air Force (IAF) and the Pakistan Air Force (PAF) engaging in combat for the first time since independence. Though the two forces had previously faced off in the First Kashmir War during the late 1940s, that engagement was very limited in scale compared to the 1965 conflict. The IAF was flying large numbers of Hawker Hunter, Indian-manufactured Folland Gnats, de Havilland Vampires, EE Canberra bombers and a squadron of MiG-21s. The PAF's fighter force comprised 102 F-86F Sabres and 12 F-104 Starfighters, along with 24 B-57 Canberra bombers. During the conflict the PAF was out-numbered by around 5:1.^[19]
The PAF's aircraft were largely of American origin, whereas the IAF flew an assortment of Soviet and European aeroplanes. It has been widely reported that the PAF's American aircraft were superior to those of the InAF, but according to some experts this is untrue because the InAF's MiG-21, Hawker Hunter and Folland Gnat fighters actually had higher performance than their PAF counter-part, the F-86 Sabre.^[20] Although the InAF's de Havilland Vampire fighter-bombers were outdated in comparison to the F-86 Sabre, the Hawker Hunter fighters were superior in both power and speed to the F-86 according to Air Cdre (retired) Sajjad Haider, who lead the PAF's No.19 Squadron in combat during the war.^[21]
According to the Indians, the F-86 was vulnerable to the diminutive Folland Gnat, nicknamed "Sabre Slayer."^[22] The PAF's F-104 Starfighter of the PAF was the fastest fighter operating in the subcontinent at that time and was often referred to as "the pride of the PAF". However, according to Air Cdre (retired) Sajjad Haider who flew with the PAF's No.19 Squadron, the F-104 did not deserve this reputation. Being "a high level interceptor designed to neutralise Soviet strategic bombers in altitudes above 40,000 feet," rather than engage in dogfights with agile fighters at low altitudes, it was "unsuited to the tactical environment of the region."^[23] It can be argued that, although the IAF is believed to have feared the Starfighter,^[23] in combat it was not as effective as the IAF's far more agile, albeit much slower, Folland Gnat fighter.^[24][25]

The two countries have made contradictory claims of combat losses during the war and few neutral sources have verified the claims of either country. The PAF claimed it shot down 104 IAF planes and lost 19 of its own, while the IAF claimed it shot down 73 PAF planes and lost 35.^[26] According to one independent source, the PAF flew 86 F-86 Sabres, 10 F-104 Starfighters and 20 B-57 Canberras in a parade soon after the war was over. Thus disproving the IAF's claim of downing 73 PAF fighters, which at the time constituted nearly the entire Pakistani front-line fighter force.^[27]
Indian sources have pointed out that, despite PAF claims of losing only a squadron of combat craft, Pakistan sought to acquire additional aircraft from Indonesia, Iraq, Iran, Turkey and China within 10 days of the beginning war.^{[citation needed]} But this could be explained by the 5:1 disparity in numbers faced by the PAF.^{[citation needed]}

Tank battles 

 he 1965 war witnessed some of the largest tank battles since World War II. At the beginning of the war, the Pakistani Army had both a numerical advantage in tanks, as well as better equipment overall.^[28] Pakistani armour was largely American-made; it consisted mainly of Patton M-47 and M-48 tanks, but also included many M4 Sherman tanks, some M24 Chaffee light tanks and M36 Jackson tank destroyers, equipped with 90 mm guns.^[29] The bulk of India's tank fleet were older M4 Sherman tanks; some were up-gunned with the French high velocity CN 75 50 guns and could hold their own, whilst some older models were still equipped with the inferior 75 mm M3 L/40 gun. Besides the M4 tanks, India fielded the British-made Centurion Tank Mk 7, with the 105 mm Royal Ordnance L7 gun, and the AMX-13, PT-76, and M3 Stuart light tanks. Pakistan fielded a greater number and more modern artillery; its guns out-ranged those of the Indian artillery, according to Pakistan's Major General T.H. Malik.^[30]

At the outbreak of war in 1965, Pakistan had about 15 armoured cavalry regiments, each with about 45 tanks in three squadrons. Besides the Pattons, there were about 200 M4 Shermans re-armed with 76 mm guns, 150 M24 Chaffee light tank and a few independent squadrons of M36B1 tank destroyers. Most of these regiments served in Pakistan's two armoured divisions, the 1st and 6th Armoured divisions – the latter being in the process of formation.
The Indian Army of the time possessed 17 cavalry regiments, and in the 1950s had begun modernizing them by the acquisition of 164 AMX-13 light tanks and 188 Centurions. The remainder of the cavalry units were equipped with M4 Shermans and a small number of M3A3 Stuart light tanks. India had only a single armoured division, the 1st 'Black Elephant' Armoured Division, also called 'Fakhr-i-Hind' ('Pride of India'), which consisted of the 17th Cavalry (The Poona Horse), the 4th Hodson's Horse, the 16th 'Black Elephant' Cavalry, the 7th Light Cavalry, the 2nd Lancers, the 18th Cavalry and the 62nd Cavalry, the two first named being equipped with Centurions. There was also the 2nd Independent Armoured Brigade, one of whose three regiments, the 3rd Cavalry, was also equipped with Centurions.
Despite the qualitative and numerical superiority of Pakistani armour,^[31] Pakistan was outfought on the battlefield by India, which made progress into the Lahore-Sialkot sector, whilst halting Pakistan's counteroffensive on Amritsar.^[32];^[33] they were sometimes employed in a faulty manner, such as charging prepared defenses during the defeat of Pakistan's 1st Armoured Division at Assal Uttar.

 Although India's tank formations experienced same results, India's attack at the Battle of Chawinda, led by its 1st Armored Division and supporting units, was brought to a grinding halt by the newly raised 6th Armoured Division (ex-100th independent brigade group) in the Chawinda sector. The Indians lost 120 tanks at Chawinda.^[34] One true winner to emerge was India's Centurion battle tank, with its 105 mm gun and heavy armour, which proved superior to the overly complex Pattons and their exaggerated reputations.^[33].However, in the Sialkot sector outnumbered Pattons performed exceedingly well in the hands of the 25th Cavalry and other regiments of the 6th Armoured Division, which exacted a disproportionately heavy toll of Centurions from the Poona Horse and Hodson's Horse. The Indian Army has made much of the fact that some of its Centurions survived repeated hits; yet have failed to point out that the majority of tanks in the Sialkot sector were Shermans whose guns were inadequate even in 1944. Neither the Indian nor Pakistani Army showed any great facility in the use of armoured formations in offensive operations, whether the Pakistani 1st Armoured Division at Asal Uttar or the Indian 1st Armoured Division at Chawinda. In contrast, both proved adept with smaller forces in a defensive role such a the 2nd Armoured Brigade at Asal Uttar and the 25th Cavalry at Chawinda, where they defeated their better equipped but clumsier foes
  

Naval hostilities

The navies of India and Pakistan did not play a prominent role in the war of 1965, although Pakistani accounts dispute this.^[35] On September 7, a flotilla of the Pakistani Navy carried out a small scale bombardment of the Indian coastal town and radar station of Dwarka, which was 200 miles (300 km) south of the Pakistani port of Karachi. Codenamed Operation Dwarka, it did not fulfill its primary objective of disabling the radar station and there was no immediate retaliatory response from India. Later, some of the Indian fleet sailed from Bombay to Dwarka to patrol the area and deter further bombardment. Foreign authors have noted that the "insignificant bombardment"^[36] of the town was a "limited engagement, with no strategic value."^[35]
According to some Pakistani sources, one submarine, PNS Ghazi, kept the Indian Navy's aircraft carrier INS Vikrant besieged in Bombay throughout the war. Indian sources claim that it was not their intention to get into a naval conflict with Pakistan, and wished to restrict the war to a land-based conflict.^[37] Moreover, they note that the Vikrant was in dry dock in the process of refitting. Some Pakistani defence writers have also discounted claims that the Indian Navy was bottled up in Bombay by a single submarine, instead stating that 75% of the Indian Navy was under maintenance in harbour.^[38]

Covert operations

The Pakistan Army launched a number of covert operations to infiltrate and sabotage Indian airbases.^[39] On September 7, 1965, the Special Services Group (SSG) commandos were parachuted into enemy territory. According to Chief of Army Staff General Musa Khan, about 135 commandos were airdropped at three Indian airfields(Halwara, Pathankot and Adampur). The daring attempt proved to be an "unmitigated disaster".^[39] Only 22 commandos returned to Pakistan as planned, 93 were taken prisoner (including one of the Commanders of the operations, Major Khalid Butt), and 20 were killed in encounters with the army, police or civilians^[40] The reason for the failure of the commando mission is attributed to the failure to provide maps, proper briefings and adequate planning or preparation^[41]
Despite failing to sabotage the airfields, Pakistan sources claim that the commando mission affected some planned Indian operations. As the Indian 14th Infantry Division was diverted to hunt for paratroopers, the Pakistan Air Force found the road filled with transport, and destroyed many vehicles.^[42]

 Assessment of losses

 India and Pakistan make widely divergent claims about the damage they inflicted on each other and the amount of damage suffered by them. The following summarizes each nation's claims.

 Neutral assessments

There have been several neutral assessments of the losses incurred by both India and Pakistan during the war. Most of these assessments agree that India had a upper hand over Pakistan when ceasefire was declared. Some of the neutral assessments are mentioned below —

• According to the United States Library of Congress Country Studies:

The war was militarily inconclusive; each side held prisoners and some territory belonging to the other. Losses were relatively heavy—on the Pakistani side, twenty aircraft, 200 tanks, and 3,800 troops. Pakistan's army had been able to withstand Indian pressure, but a continuation of the fighting would only have led to further losses and ultimate defeat for Pakistan. Most Pakistanis, schooled in the belief of their own martial prowess, refused to accept the possibility of their country's military defeat by "Hindu India" and were, instead, quick to blame their failure to attain their military aims on what they considered to be the ineptitude of Ayub Khan and his government.^[54]

• TIME magazine reported that India held 690 mi² of Pakistan territory while Pakistan held 250 mi² of Indian territory in Kashmir and Rajasthan. Additionally, Pakistan had lost almost half its armour temporarily.^[55] The same article stated that -

Severely mauled by the larger Indian armed forces, Pakistan could continue the fight only by teaming up with Red China and turning its back on the U.N.

• Devin T. Hagerty wrote in his book "South Asia in world politics"^[56] –

The invading Indian forces outfought their Pakistani counterparts and halted their attack on the outskirts of Lahore, Pakistan's second-largest city. By the time United Nations intervened on September 22, Pakistan had suffered a clear defeat.

• In his book "National identity and geopolitical visions",^[57] Gertjan Dijkink writes –

The superior Indian forces, however, won a decisive victory and the army could have even marched on into Pakistani territory had external pressure not forced both combatants to cease their war efforts.

• An excerpt from Stanley Wolpert's India,^[58] summarizing the Indo-Pakistani War of 1965, is as follows:

In three weeks the second Indo-Pak War ended in what appeared to be a draw when the embargo placed by Washington on U.S. ammunition and replacements for both armies forced cessation of conflict before either side won a clear victory. India, however, was in a position to inflict grave damage to, if not capture, Pakistan's capital of the Punjab when the cease-fire was called, and controlled Kashmir's strategic Uri-Poonch bulge, much to Ayub's chagrin.

• In his book titled The greater game: India's race with destiny and China, David Van Praagh wrote^[59] –

India won the war. It gained 1,840 square kilometers of Pakistani territory: 640 square kilometers in Azad Kashmir, Pakistan's portion of the state; 460 square kilometers of the Sailkot sector; 380 square kilometers far to the south of Sindh; and most critical, 360 square kilometers on the Lahore front. Pakistan took 540 square kilometers of Indian territory: 490 square kilometers in the Chhamb sector and 50 square kilometers around Khem Karan.

• Dennis Kux's "India and the United States estranged democracies" also provides a summary of the war.^[60]

Although both sides lost heavily in men and materiel, and neither gained a decisive military advantage, India had the better of the war. New Delhi achieved its basic goal of thwarting Pakistan's attempt to seize Kashmir by force. Pakistan gained nothing from a conflict which it had instigated.

• "A region in turmoil: South Asian conflicts since 1947" by Robert Johnson mentions^[61] –

India's strategic aims were modest – it aimed to deny Pakistani Army victory,

although it ended up in possession of 720 square miles (1,900 km²) of Pakistani territory for the loss of just 220 square miles (570 km²) of its own.

• An excerpt from William M. Carpenter and David G. Wiencek's "Asian security handbook: terrorism and the new security environment"^[62] –

A brief but furious 1965 war with India began with a covert Pakistani thrust across the Kashmiri cease-fire line and ended up with the city of Lahore threatened with encirclement by Indian Army. Another UN-sponsored cease-fire left borders unchanged, but Pakistan's vulnerability had again been exposed.

• English historian John Keay's "India: A History" provides a summary of the 1965 war^[63] –

The 1965 Indo-Pak war lasted barely a month. Pakistan made gains in the Rajasthan desert but its main push against India's Jammu-Srinagar road link was repulsed and Indian tanks advanced to within a sight of Lahore. Both sides claimed victory but India had most to celebrate.

• Uk Heo and Shale Asher Horowitz write in their book "Conflict in Asia: Korea, China-Taiwan, and India-Pakistan"^[64] –

Again India appeared, logistically at least, to be in a superior position but neither side was able to mobilize enough strength to gain a decisive victory.

• Newsweek magazine, however, praised the Pakistani military's ability to hold of the much larger Indian Army.^[65]

"By just the end of the week, in fact, it was clear that the Pakistanis were more than holding their own."

Ceasefire

The United States and the Soviet Union used significant diplomatic tools to prevent any further escalation in the conflict between the two South Asian nations. The Soviet Union, led by Premier Alexei Kosygin, hosted ceasefire negotiations in Tashkent (now in Uzbekistan), where Indian Prime Minister Lal Bahadur Shastri and Pakistani President Ayub Khan signed the Tashkent Agreement, agreeing to withdraw to pre-August lines no later than February 25, 1966.
With declining stockpiles of ammunition, Pakistani leaders feared the war tilting in India's favor. Therefore, they quickly accepted the ceasefire in Tashkent.^[66] Despite strong opposition from Indian military leaders, India budged to growing international diplomatic pressure and accepted the ceasefire.^[66] On September 22, the United Nations Security Council unanimously passed a resolution that called for an unconditional ceasefire from both nations. The war ended the following day.
India's Prime Minister, Shastri, suffered a fatal heart attack soon after the declaration of the ceasefire. As a consequence, the public outcry in India against the ceasefire declaration transformed into a wave of sympathy for the ruling Indian National Congress.^[67] The ceasefire was criticized by many Pakistanis who, relying on fabricated official reports and the controlled Pakistani press, believed that the leadership had surrendered military gains. The protests led to student riots.^[68] Pakistan State's reports had suggested that their military was performing admirably in the war – which they incorrectly blamed as being initiated by India – and thus the Tashkent Declaration was seen as having forfeited the gains.^[69] Some recent books written by Pakistani authors, including one by ex-ISI chief titled "The Myth of 1965 Victory",^[70] allegedly exposed Pakistani fabrications about the war, but all copies of the book were bought by Pakistan Army to prevent publication because the topic was "too sensitive".^[71][72]
India and Pakistan accused each other of ceasefire violations; India charged Pakistan with 585 violations in 34 days, while Pakistan countered with accusations of 450 incidents by India.^[73] In addition to the expected exchange of small arms and artillery fire, India reported that Pakistan utilized the ceasefire to capture the Indian village of Chananwalla in the Fazilka sector. This village was recaptured by Indian troops on 25 December. On October 10, a B-57 Canberra on loan to the PAF was damaged by 3 SA-2 missiles fired from the IAF base at Ambala.^[74] A Pakistani Army Auster was shot down on 16 December, killing one Pakistani army captain and on 2 February 1967, an AOP was shot down by IAF Hunters.
The ceasefire remained in effect until the start of the Indo-Pakistani War of 1971.

 Intelligence failures

Strategic miscalculations by both India and Pakistan ensured that the war ended in a stalemate —

Indian miscalculations

Indian military intelligence gave no warning of the impending Pakistan invasion. The Indian Army failed to recognize the presence of heavy Pakistani artillery and armaments in Chumb and suffered significant losses as a result.
The "Official History of the 1965 War", drafted by the Ministry of Defence of India in 1992, was a long suppressed document that revealed other miscalculations. According to the document, on September 22 when the Security Council was pressing for a ceasefire, the Indian Prime Minister asked commanding Gen. Chaudhuri if India could possibly win the war, were he to delay accepting the ceasefire. The general replied that most of India's frontline ammunition had been used up and the Indian Army had suffered considerable tank losses. It was determined later that only 14% of India's frontline ammunition had been fired and India held twice the number of tanks as Pakistan. By this time, the Pakistani Army had used close to 80% of its ammunition.
Air Chief Marshal (retd) P.C. Lal, who was the Vice Chief of Air Staff during the conflict, points to the lack of coordination between the IAF and the Indian army. Neither side revealed its battle plans to the other. The battle plans drafted by the Ministry of Defence and General Chaudhari, did not specify a role for the Indian Air Force in the order of battle. This attitude of Gen. Chaudhari was referred to by ACM Lal as the "Supremo Syndrome", a patronizing attitude sometimes held by the Indian army towards the other branches of the Indian Military.^[45]
 

Pakistani miscalculations

The Pakistani Army's failures started with the supposition that a generally discontented Kashmiri people, given the opportunity provided by the Pakistani advance, would revolt against their Indian rulers, bringing about a swift and decisive surrender of Kashmir. The Kashmiri people, however, did not revolt. Instead, the Indian Army was provided with enough information to learn of Operation Gibraltar and the fact that the Army was battling not insurgents, as they had initially supposed, but Pakistani Army regulars.


The Pakistani Army also failed to recognize that the Indian policy makers would order an attack on the southern sector in order to open a second theater of conflict. Pakistan was forced to dedicate troops to the southern sector to protect Sialkot and Lahore instead using them to support penetrating into Kashmir.
"Operation Grand Slam", which was launched by Pakistan to capture Akhnoor, a town north-east of Jammu and a key region for communications between Kashmir and the rest of India, was also a failure. Many Pakistani commentators criticized the Ayub Khan administration for being indecisive during Operation Grand Slam. These critics claim that the operation failed because Ayub Khan knew the importance of Akhnur to India (having called it India's "jugular vein") and did not want to capture it and drive the two nations into an all-out war. Despite progress being made in Akhnur, General Ayub Khan relieved the commanding Major General Akhtar Hussain Malik and replaced him with Gen. Yahya Khan. A 24-hour lull ensued the replacement, which allowed the Indian army to regroup in Akhnur and successfully oppose a lackluster attack headed by General Yahya Khan. "The enemy came to our rescue", asserted the Indian Chief of Staff of the Western Command. Later, Akhtar Hussain Malik criticized Ayub Khan for planning Operation Gibraltar, which was doomed to fail, and for relieving him of his command at a crucial moment in the war. Malik threatened to expose the truth about the war and the army's failure, but later dropped the idea for fear of being banned.^[75]
Some authors have noted that Pakistan might have been emboldened by a war game – conducted in March 1965, at the Institute of Defence Analysis, USA. The exercise concluded that, in the event of a war with India, Pakistan would win.^[76][77] Other authors like Stephen Philip Cohen, have consistently commented that the Pakistan Army had "acquired an exaggerated view of the weakness of both India and the Indian military... the 1965 war was a shock".^[78]
 Pakistani Air Marshal and Commander-in-Chief of PAF during the war, Nur Khan, later said that the Pakistan Army, and not India, should be blamed for starting the war.^[79][80] However propaganda in Pakistan about the war continued; the war was not rationally analyzed in Pakistan,^[81][82] with most of the blame being heaped on the leadership and little importance given to intelligence failures that persisted until the debacle of the 1971 war, when then East Pakistan was invaded by India and seceded from West Pakistan, leading to the creation of Bangladesh.

Involvement of other nations

The United States of America, which had previously supplied military equipment to India and Pakistan, imposed an embargo against further supplies to both countries once the war had started. The US was apprehensive that military equipment that it had provided to be used in a battle against communism, would instead be used by the countries to fight one another. The American embargo especially affected Pakistan since the majority of its equipment was provided by America. This would cause Pakistan to believe that it could not continue the war beyond September.^[83]
Following imposition of the American embargo, other NATO allies (including the UK) discontinued providing military equipment to the nations.
Both before and during the war, China had been a major military associate of Pakistan and had invariably admonished India, with whom it had fought a war in 1962. There were also reports of Chinese troop movements on the Indian border to support Pakistan.^[84] As such, India agreed to the UN mandate in order to avoid a war on both borders.
India's participation in the Non-Aligned Movement yielded little support from its members. Pakistan, however, gained assistance from countries of Asia with large Islamic populations, including Turkey, Iran and Indonesia. The USSR was more neutral than most other nations during the war and even invited both nations to talks that it would host in Tashkent.^[85][86]
 Aftermath



India

Despite the declaration of a ceasefire, India was perceived as the victor due to its success in halting the Pakistan-backed insurgency in Kashmir.^[87] In its October 1965 issue, the TIME magazine quoted a Western official assessing the consequences of the war^[88] —

Now it's apparent to everybody that India is going to emerge as an Asian power in its own right.

In light of the failures of the Sino-Indian War, the outcome of the 1965 war was viewed as a "politico-strategic" victory in India. The Indian premier, Lal Bahadur Shastri, was hailed as a national hero in India.^[89]
While the overall performance of the Indian military was praised, military leaders were criticized for their failure to effectively deploy India's superior armed forces so as to achieve a decisive victory over Pakistan.^[90] In his book "War in the modern world since 1815", noted war historian Jeremy Black said that though Pakistan "lost heavily" during the 1965 war, India's hasty decision to call for negotiations prevented further considerable damage to the Pakistan Armed Forces. He elaborates^[91] —

India's chief of army staff urged negotiations on the ground that they were running out ammunition and their number of tanks had become seriously depleted. In fact, the army had used less than 15% of its ammunition compared to Pakistan, which had consumed closer to 80 percent and India had double the number of serviceable tanks.

As a consequence, India focussed on enhancing communication and coordination within and among the triservices of the Indian Armed Forces. Partly as a result of the inefficient information gathering preceding the war, India established the Research and Analysis Wing for external espionage and intelligence. Major improvements were also made in command and control to address various shortcomings and the positive impact of these changes was clearly visible during the Indo-Pakistani War of 1971 when India achieved a decisive victory over Pakistan within two weeks.
China's repeated threats to intervene in the conflict in support of Pakistan increased pressure on the government to take an immediate decision to develop nuclear weapons.^[92] Despite repeated assurances, the United States did little to prevent extensive use of American arms by Pakistani forces during the conflict which irked India.^[93] At the same time, the United States and United Kingdom refused to supply India with sophisticated weaponry which further strained the relations between the West and India.^[94] These developments led to a significant change in India's foreign policy — India, which had previously championed the cause of non-alignment, distanced itself further from Western powers and developed close relations with the Soviet Union. By the end of 1960s, the Soviet Union emerged as the biggest supplier of military hardware to India.^[95] From 1967 to 1977, 81% of India's arms imports were from the Soviet Union.^[96] After the 1965 war, the arms race between India and Pakistan became even more asymmetric and India was outdistancing Pakistan by far.^[97]
  
Pakistan
At the conclusion of the war, many Pakistanis considered the performance of their military to be positive. September 6 is celebrated as 'Defence Day' in Pakistan, in commemoration of the successful defence of Lahore against the Indian army. The performance of the Pakistani Air Force, in particular, was praised.
However, the Pakistani government was accused by foreign analysts of spreading disinformation among its citizens regarding the actual consequences of the war.^[98] In his book "Mainsprings of Indian and Pakistani foreign policies", S.M. Burke writes^[56] —

After the Indo-Pakistani war of 1965 the balance of military power had decisively shifted in favor of India. Pakistan had found it difficult to replace the heavy equipment lost during that conflict while her adversary, despite her economic and political problems, had been determinedly building up her strength.

Most observers agree that the myth of a mobile, hard hitting Pakistan Army was badly dented in the war, as critical breakthroughs were not made.^[99] Several Pakistani writers criticized the military's ill-founded belief that their "martial race" of soldiers could defeat "Hindu India" in the war.^[100][101] Rasul Bux Rais, a Pakistani political analyst wrote^[102] –

The 1965 war with India proved that Pakistan could neither break the formidable Indian defenses in a blitzkrieg fashion nor could she sustain an all-out conflict for long.

Moreover, Pakistan had lost more ground than it had gained during the war and, more importantly, failed to achieve its goal of occupying Kashmir; this result has been viewed by many impartial observers as a defeat for Pakistan.^{[103][104][105]}
Many high ranking Pakistani officials and military experts later criticized the faulty planning of Operation Gibraltar that ultimately led to the war. The Tashkent declaration was also criticized in Pakistan, though few citizens realised the gravity of the situation that existed at the end of the war. Political leaders were also criticized. Following the advice of Zulfikar Ali Bhutto, Pakistan's foreign minister, Ayub Khan had raised very high expectations among the people of Pakistan about the superiority – if not invincibility – of its armed forces,^[106] but Pakistan's inability to attain its military aims during the war, created a political liability for Ayub.^[107] The defeat of its Kashmiri ambitions in the war led to the army's invincibility being challenged by an increasingly vocal opposition.^[108]
One of the most far reaching consequences of the war was the wide-scale economic slowdown in Pakistan.^[109][110] The cost of the 1965 war put an end to the impressive period economic growth Pakistan had experienced during early 1960s. Between 1964 and 1966, Pakistan's defence spending rose from 4.82% to 9.86% of GDP, putting tremendous strain on Pakistan's economy. By 1970–71, defence spending comprised a whopping 55.66% of government expenditure.^[111]
Pakistan was surprised by the lack of support by the United States, an ally with whom the country had signed an Agreement of Cooperation. USA declared its neutrality in the war by cutting off military supplies to both sides,^[9] leading Islamabad to believe that they were "betrayed" by the United States.^[112] After the war, Pakistan would increasingly look towards China as a major source of military hardware and political support.
Another negative consequence of the war was the growing resentment against the Pakistani government in East Pakistan (present day Bangladesh),^[78] particularly for West Pakistan's obsession with Kashmir.^[113] Bengali leaders accused the central government of not providing adequate security for East Pakistan during the conflict, even though large sums of money were taken from the east to finance the war for Kashmir.^[114] In fact, despite some Pakistan Air Force attacks being launched from bases in East Pakistan during the war, India did not retaliate in that sector,^[115] although East Pakistan was defended only by an understrenghted infantry division (14 Division), sixteen planes and no tanks.^[116] Sheikh Mujibur Rahman was critical of the disparity in military resources deployed in East and West Pakistan, calling for greater autonomy for East Pakistan, which ultimately led to the Bangladesh Liberation war and another war between India and Pakistan in 1971.
