Those Booth Horses Again -

[JMadonna]

I don't care how much adrenalin Booth had going through him, he could not have mounted that mare the way she was moving around using his allegedly broken left leg in the stirrup.

Peanuts Boroughs rested on a bench while holding the horse, didn't he? Is it possible JWB mounted the horse from that bench (thus without using the stirrup)?

Don't know about a bench but I can't see running top speed and jumping on a bench with a broken leg anymore than expecting a broken leg to hold all my weight while getting in a stirrup.

He'd have a better chance of vaulting off the horse's rear quarters and into the saddle like the old movies.
