illustrations for the hardcover of Slim were by Robert Lawson and do not appear in the paperback releases. His next novel, High Tension (1938), was a critical success but less successful financially. His novel The Winter War (1961), about the 1877 winter campaign of the U.S. Army against the Sioux in Montana, was at the time of its publication a popular western and was awarded the Spur Award of the Western Writers of America. He also published a non-fiction book, Ultra in 1980, also based on his World War II experiences as an intelligence officer. His other books were The Honorable Rocky Slade (1955), Target (1964), and The Image (1968). His filmography credits are Alibi Ike (1935), Man of Iron (1935), Black Legion (1937), Slim (1937), Mr. Dodd Takes the Air (1937), Submarine D-1 (1937), The Texans (1938), Beyond Glory (1948), Command Decision (1948), The Racket (1951), One Minute to Zero (1952), The Eternal Sea (1955), The Wings of Eagles (1957), and Torpedo Run (1958). Haines was a member of the Authors Guild and the Dramatists Guild of America. He also contributed various articles and stories to magazines. His short story "Remarks-None" was published in the railroad story anthology Headlights and Markers in 1968. Command Decision While in Europe, Haines began writing a stage play, Command Decision, based on his 8th Air Force experiences, but was unable to sell it. Many producers rejected it, feeling it followed too closely the war's end to have popular appeal. A publisher suggested he write it as a novel, which first appeared as a four-part serial in The Atlantic Monthly between October 1946 and 1947. In January 1947, the first edition of Command Decision brought Haines critical and popular acclaim. The success of the novel revived the play, which ran for 409 performances on Broadway between October 1947 and September 1948. In May 1947 Haines reached a deal with MGM Studios to sell it the film rights for $100,000, with an additional promise of 15% of the play's weekly gross (or approximately $300,000) if the play opened by October 1947. Command Decision as a feature film starring Clark Gable premiered in December 1948. The film and book have been called the first important work of fiction about World War II. They differ from most of the prior war-themed works from that period, which stressed the experiences of average citizens forced to go to war,
