Operation Cactus Lilly, better known as The Meghna Heli Bridge or the Crossing of the Meghna, was an air assault operation conducted between 9 and 12 December 1971 during the Indo-Pakistani War of 1971. It was conducted by the Indian Army and Indian Air Force to cross the Meghna River, bypass a Pakistani stronghold at Ashuganj/Bhairab Bazar and reach Dhaka. The operation is generally regarded as the brainchild of Maj. Gen. (later Lt. Gen.) Sagat Singh. Without it, Indian forces would not have been able to complete the encirclement of Dhaka and it would likely have led to a lengthening of the war.
