Correct. He had an interesting life, and ended up in New York City as a sports writer. Of the three I mentioned, he was the only one to "die with his boots on," although they were probably patent leather. He died at his desk of a heart attack, trying to meet the deadline for his daily column in the New York Morning Telegraph.
He had a number of writers for friends, and his exploits got much larger than life in his and his friends' stories. He was only confirmed to have killed one man in a gunfight, in Dodge City.
So, your turn!
