Coimbatore: On the golden jubilee year of the 1971 Indo-Pakistan war, which came to an end with the surrender of about 93,000 Pakistani soldiers and the liberation of Bangladesh, Brigadier Mahadevan recalled his memories about the Battle of Gangasagar that took place near a railway station on the international border. As Tripura side was filled with jungle and the other side with paddy fields and marshland, the brigadier said the team had to plan cautiously. Once he, along with two majors, had crossed the border to collect data. He had also infiltrated Gangasagar from the southern side, when the opponents were least expecting it. Despite his severe injury, the brigadier fought the battle till the end and was rescued by the Indian Air Force.
