A friend kindly invited me to look at a television production he had recorded, called "War Horse: the Real Story".
The show was interesting, but quite superficial in spite of having had contributions by experts such as Brough Scott and Dr. David Kenyon.
Brough Scott is the grandson of Brigadier Jack Seely, who commanded the Canadian Cavalry Brigade through most of World War I. Scott wrote "Galloper Jack", about his grandfather.
Dr Kenyon is a historian and notable author of "Horsemen in No Man's Land", a rexamination of the effectiveness of cavalry in the Great War.
I commend both books to anyone interested in the Canadian cavalry and the British cavalry in general.
"War Horse: the Real Story" was a sanitized version of the story of Warrior, Seely's charger during the conflict and after. Obviously meant for an English audience, it only mentioned in passing that Seely's main (but not only) claim to fame was his leadership of the Canadian Cavalry Brigade.
Here are some earlier thoughts about the movie "War Horse", Spielberg's 2011 production.
