Meghna Heli Bridge, codenamed Operation Cactus Lilly, was an aerial operation of the Indian Air Force during the Indo-Pakistani War of 1971, commencing India's involvement in Bangladesh Liberation War. It took place on 9 December, when the Indian Air Force (IAF) airlifted the IV Corps of the Indian Army and Mukti Bahini fighters from Brahmanbaria to Raipura in Narsingdi over the River Meghna, bypassing the destroyed Meghna Bridge and Pakistani defences in Ashuganj.
