Thank you for that account, John.
I would most certainly be interested in seeing the picture of H C Young - even though based on his imagination.
It seems on the other hand that the events were vividly etched in Walter Stafford's memory, even 50 years on. Great that you got to talk to his niece. From his account, perhaps poor Young was attempting to say his name, "Lonsdale", which Stafford heard (or remembered) as his being from Lonsdale's regiment.
Kind regards,
Alan
