Flight Lieutenant Chandra Krishna Kumar Menon joined a Hunter Squadron at Halwara on 7th September 1965, to take part in operations against Pakistan. By the time the cease-fire came into force he had carried out eight operational sorties of which seven were in close support of the army.

On 8th September, 1965, he was detailed to lead a four aircraft formation to engage targets in the Kasur-Lahore sector. His formation destroyed a supply train at Raiwind railway Station. The train was carrying ammunition badly needed by the enemy forces in the Kasur region. The denial of this vital supply of ammunition was a major factor in causing the withdrawal of the enemy armour with heavy losses. During the same mission, a large number of tanks and gun emplacements were also successfully engaged and destroyed or damaged. At least six enemy tanks were destroyed on this occasion.

In these sorties, Flight Lieutenant Chandra Krishna Kumar Menon displayed professional skill and utter disregard for his personal safety in the best traditions of the Air Force.
