Flight Lieutenant James Robert Macelwain of Number 2 Squadron successfully completed numerous low level photographic sorties and tactical reconnaissance missions. In the course of these operations, he inflicted considerable damage on the enemy's river transport, trains and mechanical transport and destroyed two flying bombs. His aircraft was hit on seven occasions but he never let either enemy opposition or adverse weather deter him from completing his mission. At dawn on D-Day, Flight Lieutenant Macelwain completed several naval bombardment shots for more than two hours at low level over the French coast despite continuous anti-aircraft fire. He neutralized three guns and only returned to base through lack of fuel.
Soon after landing, this officer took off again and flew another two hours over the heavily defended coast where he neutralized more enemy guns. Throughout his operational career this officer displayed a high standard of efficiency and a fine fighting spirit.
For his actions, he was awarded the Distinguished Flying Cross.
