Pakistani Instrument of Surrender (1971)

Pakistan Eastern Command surrenders at Dhaka

The document changed the chain of command the instant the ink was on the page: every Pakistani armed and paramilitary formation in Bangladesh came under Aurora's orders.

16:31 IST at the Race Course

On 16 December 1971, Lieutenant-General A. A. K. Niazi signed the Instrument of Surrender at Dhaka's Race Course. Lieutenant-General Jagjit Singh Aurora accepted it and signed as commander of the Indian and Bangladesh forces — a co-signatory, not a witness.

The instrument records 16:31 Indian Standard Time; Bangladeshi accounts give 17:01 Dhaka time. They are the same moment.

What the page transferred

The document surrendered all Pakistani armed, paramilitary and civil armed forces in Bangladesh. They came under Aurora's orders immediately upon signature, across the country and not only at the Race Course.

A. K. Khandaker, deputy chief of staff of the Bangladesh Forces, represented Bangladesh. Its commander-in-chief, M. A. G. Osmani, was absent.

The western front, next

Dhaka had been encircled and Pakistan's Eastern Command could no longer sustain the defense; an Indian ultimatum had demanded an immediate ceasefire and surrender.

India announced that it would halt offensive operations on the western front beginning the following day.

What the sources leave uncertain

The instrument records 16:31 Indian Standard Time, while Bangladeshi accounts commonly give 17:01 local Dhaka time; these are the same moment in the two time zones.
