DeHavilland was re-united with Flynn for their eighth movie together, Raoul Walsh's epic "They Died with Their Boots On". The film is loosely based on the courtship and marriage of George Armstrong Custer and Elizabeth "Libbie" Bacon. Flynn and deHavilland had a falling out the previous yearmainly over the roles she was being givenand she did not intend to work with him again. Even Flynn acknowledged, "She was sick to death of playing 'the girl', and badly wanted a few good roles to show herself and the world that she was a fine actress." After she learned from Warner that Flynn had come to his office saying he needed her in the film, deHavilland accepted. Screenwriter Lenore Coffee was brought in to add several romantic scenes, and improve the overall dialogue. The result is a film that includes some of their finest work together. Their last appearance on screen is Custer's farewell to his wife. "Errol was quite sensitive", deHavilland would later remember, "I think he knew it would be the last time we worked together." Flynn's final line in that scene would hold special meaning for her: "Walking through life with you, ma'am, has been a very gracious thing." "They Died with Their Boots On" was released on November 21, 1941, and while some reviewers criticised the film's historical inaccuracies, most applauded the action sequences, cinematography, and acting. Thomas M. Pryor of "The New York Times" found deHavilland "altogether captivating". The film went on to earn $2,550,000 (), Warner Bros' second-biggest money-maker of that year.
