Although "Retreat" began as a magazine story, Faulkner revised the story before it became part of the novel. One significant revision was the addition of six pages about Uncle Buck to an otherwise uninterrupted narrative. Bayard recalls Buck and Buddy's system of slave management and their competition to see who would join the regiment, as well as Uncle Buck's dialogue. The Uncle Buck section adds weight and complexity to the story, making it less frivolous. Uncle Buck appears in other Yoknapatawpha County stories, and his son Ike is a major character in Go Down, Moses. By including more details about Buck and Buddy, Faulkner weaves The Unvanquished more closely into the interconnected universe of his novels. In addition, Buck's lavish praise of Colonel Sartoris to Bayard is the first confirmation that the outside world lionizes the colonel as much as his son does. By telling Bayard stories about his father and emphasizing his special role as the colonel's son, Uncle Buck forces the boy to consider his place in the community. He underscores and creates the sense of familial responsibility that Bayard feels, adding significance to Bayard's actions at the end of the novel.
