The PAF aircraft were providing support the Pakistan Army ground units near the border area in Garibpur. The first of four Sabres were picked up in the
Jessore area on Indian
radar at 0811 hours. No.22 Squadron scrambled four Gnats from Dum Dum. A second raid by the Pakistanis followed at 1028 hours. An interception again could not be carried out in time, and the Sabres escaped to safety. At around 1448 hours, the radar picked up the three Sabres as they pulled up in a north-westerly direction to about
above ground level. Within a minute, the ORP at Dum Dum was scrambled. Four Gnats took off by 1451 hours led by the formation leader,
Flight Lieutenant Roy Andrew Massey. Less than three minutes earlier, the Sabres had been detected by the radar. The
fighter controller in the sector was
Flying Officer KB Bagchi, who vectored the Gnats to the Sabres and directed the interception. The Sabres had already carried out several attack runs during the eight minutes that it took the Gnats to reach the Boyra Salient and were starting to start another dive. They were at about altitude and were diving down to in an attack run. The four Gnats separated into two sections and dived into the attack to bounce the Sabres. The first section of Gnats was of Massey and Flying Officer SF Soarez as his
wingman. The second section consisted of Flight Lieutenant
M A Ganapathy and Flying Officer D Lazarus. As the Gnats dived in, a section of two Sabres pulled out of the attack and placed themselves in an awkward position, just in front of Ganapathy and Lazarus. Both pilots opened fire with 30 mm
autocannon fire, and both the Sabres were badly damaged. Ganapathy called out on the
R/T, the
Brevity code for "Murder Murder Murder". The Pakistani pilots (
Parvaiz Mehdi Qureshi and Khaleel Ahmed) ejected over Boyra and parachuted down safely but were taken as
prisoners-of-war. The wreckage of the abandoned Sabres fell near the village of
Bongaon, in India. Simultaneously, Massey pulled up over Ganapathy and Lazarus to latch onto another Sabre. The Sabre pilot, Wing Commander Chaudhury, in a skilful
dogfighting move broke into Massey's attack and forced him to take a high angle-off burst, which missed his target. After manoeuvring back into firing position and taking aim, Massey let off another burst at and hit him in the
port wing. By then, Massey's
starboard cannon had stopped firing, but the Sabre streaked back into Pakistani territory and billowed smoke and fire. Massey realised that he was well over East Pakistani
airspace in his chase and turned around and regrouped with the rest of his formation, which then proceeded back to base. Early on, it was thought that the badly damaged Sabre must have crashed soon afterward, but after the war, reports confirmed that Massey's victim, Wing Commander Chaudhury, showing considerable courage, had managed to fly his Sabre back to
Tezgaon Airfield, outside
Dhaka. Chaudhury claimed that he had shot down one of the Gnats, but Indian officials claimed that no aircraft were lost in the battle. ==Aftermath==
