One night in June, 1943, this airman was the pilot of a bomber which attacked the airfield at Comiso. Whilst over the target the aircraft was hit by anti-aircraft fire. The inter-communication system was rendered unserviceable, one engine was put out of action, while a fire broke out near the entrance hatch; other damage had been sustained and two of the crew were wounded. A little later, a second engine became defective, emitting sheets of flame at intervals. Despite this, Sergeant Tattersall set course for Malta and, displaying superb airmanship, succeeded in reaching an airfield on the island where he effected a masterly landing. This airman displayed great courage and determination and was largely responsible for the safe return of the aircraft and its crew.
