Major General Jonathan R. "Jack" Burton on Thackeray: "Everyone trusted Thack, and whenever a crisis developed, he could calmly straighten it out. One we were judging a fault-and-out class at Madison Square Garden. Frank Chapot knocked a lower rail off a fence, but the top rail was intact. The whistle blew, and Frank stopped after the next fence. Then the ground jury met and decided to let Chapot start over. He jumped clean, a round that would win him the class, and an uproar ensued. Riders from all the other countries protested that it was unfair to give Chapot another chance. Thack, who was on the ground jury, calmed everybody down and got the class moving again. The ground jury had been at fault in blowing the whistle, he explained, because Chapot's horse had not lowered the height of the obstacle. Thack's ability to mediate defused what would have been an international incident."
