Now this is interesting. I just found an excerpt from his biography, and here is what he was told afterwards as he had STM loss of exactly how events played out.
"I left the starting box at exactly 3:01. The times are always that precise; another rider goes every two minutes. We made a nice strong start. Witnesses said that Buck was absolutely willing and ready. First jump, no problem. The second jump was a medium-size log pile. No problem. Then we came to the zigzag. The fence judge’s report says I was going fast, not excessively fast but moving right along.Apparently Buck started to jump the fence, but all of a sudden he just put on the brakes. No warning, no hesitation, no sense of anything wrong. The judge reported that there was nothing to suggest Buck was worried about the fence. He just stopped. It was what riders call a dirty stop; it occurs without warning. Someone said that a rabbit ran out and spooked Buck. Someone said it could have been shadows. …"
And here’s where my eyewitness to the first two fences is so radically different from the “witnesses” he mentions. The horse wasn’t willing at the 2nd fence. He was anything BUT willing. Yes, he jumped it, but awkwardly, and not forward, sucking back, ears flat on his head strides before the fence, and clearly not happy. I was standing about 30 yards away with an unobstructed view of their profile, and the entire picture struck me in a very impressionable way. That horse’s attitude at that second fence was a huge “in your face” warning that the rider had to have felt in the hesitating backward approach, and had to have seen in the horse’s expression (ears). Sadly, Reeve never remembered, and had to rely upon others who certainly weren’t telling him the truth, or were too star-struck in watching him rather than the horse to really be objective about all the pieces.
Now, with almost 20 years gone past, and a whole decade within devoted to a deeper understanding and appreciation of the sport horse in the extreme sport of endurance, I couldn’t help but zero in on his comment about being worried about the horse’s sore back (which he mentions earlier in his narration) which, in turn, makes me think that the sore back may well have been the catalyst for the horse’s attitude towards the fences. If the horse was hurting, and Reeve clearly knew it and said so, it may be the reason for the vastly different opinions regarding the horse’s personality being expressed here by people who actually knew the horse.
