I have a hardback of "King of the Air Fighters" By Ira (Taff) Jones who was a Welshman (of course). It is a pretty old copy. Ira Jones was an ace in his own right and was a Wing Commander RAF in WWII and wrote the RAF official history of WWII.

Wikipedia don't mention the last, though they are often wrong. Strange that they say he was awarded the MC in Sept 1918 although I thought it had been long superceded by the DFC. According to the Wiki, he was awarded his first DFC in August 1918, the MC in September and the bar to the DFC in the same month. A bit strange.....
