Was John Wayne riding the horse in True Grit at the end when he jumped over the graveyard fence?

He was 61 when he made that movie they would have let him even if he was physically fit.

"Stunt double Jim Burk performed the entire scene where Rooster Cogburn charged Ned Pepper's gang on horseback. John Wayne was only seen briefly in close-up, and he was riding on a trailer, not a horse."

"Jim Burk doubled for John Wayne in the final jumping fence stunt at the end."
