Its not the complete answer but:

Air Ministry, i^th April, 1943.
ROYAL AIR FORCE.
The KING has been graciously pleased to approve the following awards in recognition of gallantry displayed in flying operations against the enemy: —
Bar to Distinguished Flying Cross.
Wing Commander Dudley Henderson BURNSIDE,
D.F.C. (37464), No. 427 (R.C.A.F.) Squadron.
Distinguished Flying Cross.
Pilot Officer Reginald James HAYHURST (128419),
Royal Air Force Volunteer Reserve, No. 427 (R.C.A.F.) Squadron.
One night in March, 1943, Wing Commander Burnside and Pilot Officer Hayhurst were captain and bomb aimer of an aircraft detailed to attack
Essen. When nearing the target area, the bomber was hit by anti-aircraft fire. One of the crew was killed and another severely wounded, while the
aircraft sustained damage. The aileron control was affected and the windscreen de-icing glycol tank burst drenching Pilot Officer Hayhurst and
filling the forward part of the bomber with suffocating fumes. Despite this, Pilot Officer Hayhurst directed his captain to the target which was successfully bombed and a good photograph obtained. The aircraft was held by searchlights for a few minutes but Wing Commander Burnside
skilfully evaded the defences and set course for home. On the return flight the aircraft encountered enemy fighters but, each time, he shook them off.
Displaying fine airmanship he flew the damaged aircraft back to an airfield in this country. In a very trying situation both these members of
aircraft crew displayed courage and determination of a high order.
