According to They Shall Grow Not Old, page 734, it states: " Halifax aircraft missing during low-level operations over Abbeville, France. Six members of the crew missing believed killed. Warrant Officer Pilot Stratford is buried in the Somme Cemetery, Neuf Molin, France."
There actually are two addendums that came out to make corrections to the book.
Maybe more information would be available in this airman's service file.
