Thanks to the donation of a document by Duncan Munro, I have been able to transcribe and reproduce here a copy of the Captain's official gunnery report for HMS Illustrious in relation to the Operation Excess action.
It makes particularly fascinating reading given the context that this was one of the first - certainly the first large-scale - dive bombing attacks on a warship in World War II. It was also the most intense anti-aircraft action of the war to that point.
