Dhaka, July 27 - A mission in which doctors, medical students and women volunteers saved the lives of many soldiers and freedom fighters during the Bangladesh liberation war in 1971 has been recorded in a new documentary 'Bangladesh Hospital '71'.

The hospital that was set up was actually a make-shift bamboo and wood establishment just across the border at Bisramganj, Tripura in northeastern India.

While medical help for the sick and wounded among freedom fighters and civilian refugees was on, help came from Major Khaled Mosharraf, a Pakistan army officer who turned a freedom fighter.

He gave Taka 50,000 (worth $900 now) and assigned an army doctor, Major Akhtar Ahmed, to organise the hospital, The Daily Star newspaper said Monday.

The 29-minute film records 'many untold stories', said Habib Wahid, who edits a magazine Aninda and made the film scripted by Lutful Hussain 'to inform the post-war generations'.
