The Tangail Airdrop was an airborne operation mounted on 11 December 1971 by the 2nd Parachute Battalion Group of the Indian Army during the Indo-Pakistani War of 1971. The main objective of the operation was the capture of Poongli Bridge on the Jamuna which would cut off the 93 Brigade of Pakistani Army which was retreating from the north to defend Dacca and its approaches. The Paratroop unit was also tasked to link up with the advancing Maratha Light Infantry on the ground to advance towards the East Pakistani capital.
The Paratroopers, numbering 700 and led by Lt Col Kulwant Singh Pannu was reinforced by an Artillery battery, an Engineering detachment, an ADS, and a surgical team and other administrative troops from 50th (Indep) Parachute Brigade. Tasked to cut off the retreat of the Pakistani troops from the north towards Dacca, the unit touched ground at 4:30pm and were greeted by a jubilant crowd of local Bengali populace, with some even helping the troops carry their packs and ammunition. The drop was dispersed over a wide area, but the Paras regrouped quickly and commenced their attack. By 7.00pm they had captured their main objective, cutting off the Pakistani 93 Brigade retreating from the north. Link-up with 1 Maratha LI was established after the Marathas broke through at Tangail Road and reached the bridgehead that very evening. The Pakistanis, attempting to retake the bridge rushed the Indian positions that evening, however, were repulsed. The Tangail Airdrop operation involved An-12, C-119s, 2 Caribous and Dakotas from 11 sqn and 48 Sqn. The IAF also carried out feint drops using dummies dropped from Caribou aircraft to hide the true location and extent of the operation. The only hitch was a Hangup from the lead Dakota. One Paratrooper had a static line hangup, who, after carrying out emergency procedures, was dropped safely about 50 miles away.
The Tangail Airdrop and the subsequent capture of the Poongli bridge over Jamuna by 2nd Para Bn Gp gave the advancing Indian Army the maneouverability to side step the strongly held Tongi-Dacca Road to take the undefended Manikganj-Dacca Road right up to Mirpur Bridge at the gates of Dacca.
