If it helps, this appears to be the rest of his crew:-
Name: CRAIG, ARTHUR ERNEST
Initials: A E
Nationality: United Kingdom
Rank: Sergeant
Regiment/Service: Royal Air Force
Unit Text: 18 Sqdn.
Date of Death: 21/05/1940
Service No: 358376
Casualty Type: Commonwealth War Dead
Grave/Memorial Reference: Panel 13.
Memorial: RUNNYMEDE MEMORIAL
Edit: Have looked up the initial Flight pages for the award of his DFM:
Sgt William Joseph Cronin, Sgt Frank Miller, Sergeant Alexander Cameron Thomas, Sgt David Pennington, Leading A/C George Hawkins and L A/C Sidney Culver..... "during a 25 minute engagement over North Sea between 9 Blenheims and 5 Me110's on 19th January 1940....."
From what I can find, it would appear that it was No 110 Squadron that had the encounter with the Me110's losing 4 crew that day....
so, whilst I can't find any record of what he was awarded a DFM, I hope I have ruled out 10th January engagement from the search....
Now found the Casualty report in Flight
http://www.flightglobal.com/pdfarchi...0-%201735.html which shows him as Sgt GDFM Hawkins - including his DFM as initials!! His pilot, C Light also appears, so I think it's him....
