Statement, Red Cross File No 08205121, 3500 Pte B.R. BROCK, 14th Machine Gun Company (patient, 1st Australian Auxiliary Hospital, Harefield, England), 26 October 1916: 'We went over the trenches together from our second line at Fleurbaix and he went about 15 yards ahead, when a bullet hit him, I should think he was killed at once from the way he fell, this was 19th July about 5 p.m. I stopped to look at him, saw it was hopeless and went on, we held the ground for 500 yards ahead of where he fell. I never saw him after he fell. He was a very popular officer.'

He couldn't have been buried anywhere.'

Cox was wounded soon after he got over the parapet, he was unable to get back to our trench and whilst lying in No Mans (sic) Land he was blown to pieces or buried by shell. It was impossible to go out and fetch him in the time he was wounded as shell fire was so heavy. No sign of his body could be seen when we went out the following day.'
