In September, 1965, Flight Lieutenant Wishnu Mitter Sondhi was sub-section leader in the second formation of Vampires that struck the enemy in the armour in Chhamb Sector. Fully aware that the first section was jumped by an enemy F-86 formation, he kept a sharp look out for the enemy aircraft even when attacking the enemy armour with rockets. Undaunted by the presence of the enemy aircraft of superior performance, he delivered his rockets against the enemy tanks. He sighted a formation of F-86 and registered several hits on it. Meanwhile his wingman warned him of other F-86s closing in astern and Flight Lieutenant Wishnu Mitter Sondhi had to break off to avoid being hit. His wingman was shot down and he alone of his section fought his way back to base. His cool courage and flying skills were in the best traditions of the Air Force.
