Squadron Leader Shri Krishna Singh was in charge of ground defence and security arrangements of an airfield when hostilities started with Pakistan. On 6th September 1965, over 60 Pakistani paratroopers, equipped with modern weapons and equipment, were air-dropped in the vicinity of the unit to carry out sabotage to our aircraft and installations. Squadron Leader Singh organised a mobile patrol and under his intelligent and able direction, the patrol foiled the enemy’s plan. Finding the airfield defences formidable, the paratroopers finally withdrew from the airfield and were captured by civil and army authorities.

On 7th September, 1965, when information was received that some paratroopers had been hiding near a village, Squadron Leader Shri Krishna Singh volunteered to lead a mobile armed patrol to apprehend them. During this operation, he was able to apprehend three paratroopers, including the officer in charge of the Pakistani Para contingent. On an extensive search made under his supervision, 70 parachutes and a considerable quantity of automatic weapons and other equipment were captured. This bold action on the part of Squadron Leader Shri Krishna Singh made the paratroopers attack on the airfields ineffective.
