Flight Lieutenant Martins was serving with a transport squadron operating in NEFA. During the different phases of the battle of Walong, the vital supplies required by the piquets and retreating columns had to be supplied by airdrops. Flight Lieutenant Martins carried out numerous sorties over hazardous and unmapped areas for this purpose. In spite of the danger of anti-aircraft fire from the encircling Chinese troops, he always volunteered to undertake these missions, in complete disregard of his personal safety.
Flight Lieutenant Martins displayed courage and devotion to duty of a high order.
