Two Dakotas from Jorhat, likely of the 49 Squadron, were assigned the task of dropping supplies at the post. The aircraft had to fly low, amidst small arms fire at them. One aircraft was able to drop water, but neither was successful in helping replenish the post. Both aircraft had bullet holes.
The second aircraft, HJ-233, had four crew -- Flight Lieutenant AS Singha (Pilot, 4679), Flag Officer RE Raphael (Co-pilot, 5660), Flag Officer CS Misra (Nav, 5455) and Seargent JC Chowdhury (Signaller) -- besides five ejection crew, who were Armymen. Its first drop was not on the mark due to the firing.
During the second run by the HJ-233, both engines of the aircraft were hit and one cut out. Flt Lt Singha managed to crash-land in a paddy field in Zathsu in the mountainous terrain without serious injury to any of his crew. Surrounded and fired upon, the four crew and five passengers were captured.
