Flight Lieutenant Dil Mohan Singh Kahai was the deputy leader of a Mystere formation, which carried out a daring daylight raid on the very heavily defended Sargodha airfield on 7th September 1965. Despite the intense anti-aircraft fire, he dropped his bombs on four parked aircraft (one F-104 and three F-86) on the Operational Readiness Platform. Then he straffed two more F-86 aircraft and one more F-104 parked on the other Operational Readiness Platform.

On 11th September 1965, he flew as No. 2 in a two-aircraft bombing mission over artillery bunkers in the Lahore sector. The bombs dropped by him exploded directly over the bunkers and they were destroyed.

On 18th September 1965, flying again as the deputy leader in a four aircraft formation, Flight Lieutenant Kahai scored a direct hit on a gun position near Lahore airfield with rockets and knocked it out. On 19th September, 1965, he led a two aircraft formation and destroyed a Railway Bridge over the Ichhogil canal.

The officer also flew a number of strike support missions in which he inflicted damage to enemy equipment and casualties on enemy troops. He also carried out armed patrol sorties near the airfield.

The calmness and resolute courage displayed by Flight Lieutenant Dil Mohan Singh Kahai during all these operational missions were a source of inspiration to other pilots and were in the best traditions of the Air Force.
