The aerial phase of the war began on 1 September 1965, when the Indian Air Force (IAF) responded to an urgent call for air strikes against the
Pakistani Army (which had begun
Operation Grand Slam. The IAF quickly launched 26 aeroplanes (12
de Havilland Vampires and 14
Dassault Mystère IVs) to blunt the Pakistan Army's offensive in
Chhamb. The IAF's 45th Squadron was tasked with close air support of Indian troops. The squadron, recently moved from
Pune to
Pathankot after the 220th Squadron was merged into it, was commanded by S. K. "Marshal" Dhar. Group Captain Roshan Suri painted a grim picture of the Indian Army's position at
Akhnoor and the Pakistan Army's armoured thrust at Chhamb, on the
Tawi River near
Jammu. Twenty-eight aircraft (12 Vampires and 16 Mysteres) were used, and the first planes took off at 17:19 hours. The planes flew in formation and strafed Pakistani tanks and ground targets, although
friendly fire was also later reported. When the Indian aircraft were sighted, the Pakistan Air Force (PAF) scrambled two F-86 Sabres (flown by
S/L Sarfraz Rafiqui of the No. 5 Squadron and
F/L Imtiaz Bhatti of No. 15 Squadron) to intercept. In the ensuing dogfight over Chhamb, where Rafiqui took on the flight leader and wingman and Bhatti went after the element leader and element wingman, the IAF lost all four of its Vampires; they were flown by Squadron Leader Aspi Kekobad Bhagwagar (flight leader), Flight Lieutenant Vijay Madhav Joshi (element leader), Flight Lieutenant Satish Bharadwaj (element wingman) and Flight Lieutenant (later Group Captain) Shrikrishna Vishnu Phatak (wingman). Both Pakistani pilots claimed two aircraft kills each. The IAF withdrew about 130 Vampires and over 50
Ouragons from front-line service. Although India's use of fixed-winged Vampires was later criticized, eight of the 12 Vampires successfully completed their tasks; 14 Mysteres returned unscathed, and the IAF claimed success in slowing the Pakistan Army's momentum. The PAF's Sabres forced the IAF to send
Folland Gnat fighters to the forward base at
Pathankot; India used Mysteres flying at slow speed as bait to lure the Sabres to attack, and the waiting Gnats would take them on. Two Sabres were scrambled, but one had to turn back when the pilot could not jettison its fuel tanks. The other, flown by F/L
Yusaf Ali Khan, spotted the IAF planes and tried positioning himself behind them before attacking. As Khan got them in his cross-hairs, however, he was surrounded by a group of Gnats under attack. A
Lockheed F-104 Starfighter in the area was sent to the dogfight, and another one was scrambled from the base. The first Starfighter passed through the dogfight at supersonic speed; the Gnats, after scoring a kill, began to leave. IAF Squadron Leader
Trevor Keelor of
No. 23 Squadron claimed to have shot down an F-86 Sabre on 3 September for the IAF's first air-combat victory of the war, and received the
Vir Chakra; however, the Sabre made it back to the base. Its pilot, Khan, received the
Sitara-e-Jurat for surviving the dogfight against six Gnats and bringing the damaged Sabre back home. An IAF Gnat pilot was overheard warning others of the incoming Starfighter. A Gnat flown by S/L
Brij Pal Singh Sikand mistakenly landed at an abandoned airstrip in
Pasrur after Sikand thought he had safely crossed the border. After realising his mistake, Sikand's takeoff attempt was aborted due to a Pakistan Army jeep on the runway; he was taken prisoner, and later handed over to the PAF. A Starfighter flown by F/L Hakimullah Khan at supersonic speed was credited with forcing the Gnat down, and the Gnat is on display at the
Pakistan Air Force Museum in
Karachi. but the IAF said that they shot it down. at the PAF Museum Bhatti had 34 combat missions, the most flown by any pilot during the war. According to Pakistani sources, His claim was contested by the IAF, which denied losing five Hawker Hunter aircraft that day; No verifiable
gun camera footage of Alam's kills was made public by Pakistani authorities. during
airstrikes by the PAF's
No. 19 Squadron led by
Sajad Haider. On 6 September, the
Indian Army crossed the border at
Lahore to relieve pressure on the
Chamb Jaurian sector. That evening, the PAF responded with attacks on Indian airfields at
Pathankot,
Adampur and
Halwara. The IAF lost almost ten aircraft on the ground at Pathankot, but the attacks on Adampur and Halwara were unsuccessful. The Adampur strike, led by S/L
M. M. Alam, turned back before reaching Adampur; the Halwara strike, led by S/L
Sarfraz Rafiqi, was impossible due to IAF
combat air patrol. Two Indian Hunters were lost in air combat. Both Indian pilots survived, ejecting over their base, but both Pakistani pilots (including Rafiqui) were killed. Rafiqui had shot down two Vampires and the first of the Hunters, F/L
Cecil Chaudhry returned from the pursuit. According to Indian sources, the PAF parachuted 135
Special Services Group (SSG) commandos at three Indian airfields (Halwara, Pathankot and Adampur) on 7 September. That day, the IAF mounted 33 sorties against the heavily guarded
Sargodha Airfield Complex, owned by the PAF. They lost two Mysteres and three Hunters to local PAF squadrons. One of the Indian Hunter pilots, who ejected near Sargodha, was taken prisoner and released after the war. One of the crippled Mysteres was involved in a dogfight with a Starfighter, shooting each other down. The Pakistani pilot ejected; S/L
Ajamada B. Devayya was killed, and received a posthumous
Maha Vir Chakra. During the 7 September PAF raid on
Kalaikunda, Indian F/L
A. T. Cooke engaged three PAF Sabres. Cooke shot one down and damaged a second; out of ammunition, he chased away the third Sabre (which was shot down by his wingman). On 8 September, an Indian
S-75 Dvina missile was fired against an unidentified target believed to have been on a night mission above
Ghaziabad (near
Delhi). The war then lessened in intensity, with occasional clashes between the IAF and the PAF. Both air forces changed their strategy from air interdiction to ground attack and concentrated their efforts on
soft-skinned vehicles, supply lines, wagons carrying ammunition, and armoured vehicles. IAF
English Electric Canberras raided several Pakistani bases. A 10 September battle involved eight aeroplanes over the
River Beas: two PAF F-86 Sabres (flown by S/L Muniruddin Ahmad and F/L
Imtiaz Bhatti) and six IAF planesfour Mysteres and two Gnatswith two 30 mm Aden cannons, led by F/L V. Kapila and F/L Harry Sidhu. Both IAF pilots said that their guns jammed. Both PAF pilots said that they shot and damaged one IAF aeroplane each. Same-day IAF records acknowledge losing one Mystere, with the pilot (
Fg Off D. P. Chinoy safely ejecting in Pakistan during the evening and walking back to safety at night. On 13 September, another encounter took place between PAF Sabres from Sargodha and IAF Gnats from the No. 2 Squadron. An Indian Gnat was shot down by a PAF F-86 Sabre flown by F/L Yusaf Ali Khan, After he reportedly died on landing, his funeral was attended by the
president of India. Khan was credited with a kill; Bhatti was credited with damaging the IAF Gnat, Later on the night of 13/14 September, Indian Canberras made the war's deepest penetration into Pakistani airspace and attacked bases near
Peshawar and
Kohat. Instead of bombing the Peshawer runway, however, IAF bombers mistook the mall road in Peshawer as the runway and dropped their bombs there instead. The Canberras were intercepted by a Pakistani F-104 near Lahore, but evaded the Starfighter and returned home safely. They also encountered F-86 Sabres, one of which damaged the Canberras. A Pakistani
Cessna and an
Auster observation aircraft were also shot down that day. On 19 September, a Gnat The following day, another two Hunters two Gnats were downed by PAF fighters. At one point, the IAF was operating 200 air missions simultaneously. Gnats from the
9th and
23rd squadrons played a significant role in major air battles. On 21 September, IAF Canberras made a daylight strike in Pakistan on the radar complex in
Badin. Under Wing Commander Peter Wilson, six Canberras from
No. 16 Squadron took off from
Agra (over 1,000 km from Badin) and proceeded towards the radar complex at low altitude. Identifying the wounded soldier at Kargil,
Radio Pakistan announced the capture of the younger Cariappa. General Ayub Khan contacted General Cariappa, who was retired in his hometown of
Mercara, with information about his son's safety. When Khan offered to release his son immediately, Cariappa reportedly told him to treat his son no differently from any other POW: "He is my son no longer. He is the child of this country, a soldier fighting for his motherland like a true patriot. My many thanks for your kind gesture, but I request you to release all or release none. Give him no special treatment." A
ceasefire was declared on the night of 22 September. ==Losses==
