By the winter of '62-'63 they had had a falling out. I can't put my hand on it now but there is a letter in some book, probably Dr. Robertson's, where Jackson writes to Hill's wife (his sister-in-law) about how he regrets what's happened to Hill but Hill could have prevented it, etc... something like that. Jackson provided zero details. But there was a problem.I know Hill had a vendetta for being removed from command later on, did he have one towards Jackson? Jealously for his success?
