Set during the American Civil War, the short begins with a Northern General assigning Larry, Moe, and Curly to sneak behind enemy lines and obtain secrets. Disguising themselves as southern officers and taking the names Lieutenant Duck, Captain Dodge and Major Hyde, they insinuate themselves into the mansion of southern officer, Colonel Butts. During preparations for a dinner party at the mansion, Curly, more interested in the Colonel's daughter, Judith Butts, manages to mistake a quilted potholder for a cake, resulting in a feather-coughing scene. The short concludes with an episode in which Larry and Curly disguise themselves as, respectively, Captain Dodge's father and wife. This leads to a controversial gag in which Major "Bloodhound" Filbert inquires about Captain Dodge's baby. Moe runs off and brings in a swaddled infant, which is revealed to be black, thus giving away the Stooges' charade. The three of them run for their lives and hide in a "log" — which turns out to be a hidden cannon — which is fired by the Confederates. The Union General wonders aloud where the three spies are. At that moment, the trio promptly land on the General from the sky.
Uncivil Warriors was filmed on March 13–18, 1935. It is the first short in which the Stoogesmention "Good Time Charlie". When the Stooges meet a guard, they often reference Charlie. The guard asks who Charlie is, and a Stooge replies that "everybody knows Charlie. He walks like this." The Stooges then demonstrate a silly walk until they get clear of the guard, at which point they take off running. This is a recurring joke in the Stooge shorts. In Uncivil Warriors, they actually meet a soldier named Charlie, who asks the Stooges, "Are you all looking for me?" The potholder gag would later appear in the Shemp-era short Three Hams on Rye during a live theatrical production. When Moe brings the black baby into the Colonel's office he attempts to explain how the baby got his dark complexion ; this is sometimes deleted for U.S. television broadcasts. The introductory music over the titles is a medley of "Battle Hymn of the Republic" and "Dixie".
