On Sunday, July 13, Porter approached Memphis, Missouri in four converging columns totalling 125–169 men and captured it with little or no resistance. They first raided the Federal armory, seizing about a hundred muskets with cartridge boxes and ammunition, and several uniforms (Mudd, see below, was among those who would wear the Union uniform, as he claimed, for its superior comfort in the heat, a fact which would later draw friendly fire and aggravate the view of Porter's troops as bushwhackers, neither obeying nor protected by the rules of war). They rounded up all adult males, who were taken to the court house to swear not to divulge any information about the raiders for forty-eight hours. Porter freed all militiamen or suspected militiamen to await parole, a fact noted by champions of his character. Citizens expressed their sympathies variously; Porter gave safe passage to a physician, an admitted supporter of the Union, who was anxious to return to his seriously ill wife. A verbally abusive woman was threatened with a pistol by one of Porter's troops, perhaps as a bluff; Mudd intervened to prevent bloodshed. Porter's troops entered the courthouse and destroyed all indictments for horse-theft; the act is variously understood as simple lawlessness, intervention on behalf of criminal associates, or interference with politically motivated, fraudulent charges.
