Apparently, the story of Knight is "soon to be a major motion picture."
The recovery of the life of a Mississippi farmer who fought for his country is an important story. The fact that southern Unionists existed, and in very large numbers, is largely unknown to many Americans, who grew up with textbooks that perpetuated the myth of the Confederacy as a heroic Lost Cause, with its romanticized vision of the antebellum South. Some historians have even palpably sympathized with Confederate cavaliers while minimizing—and robbing of credit—the actions of southerners who remained loyal to the Union at desperate cost.
One would never know that the majority of white Southerners had opposed secession, and that many Southern whites fought for the Union. In Tennessee, for example, somewhere around 31,000 white men joined the Union army. In Arkansas more than 8,000 men eventually served in Union regiments. And in Mississippi, Newton Knight and his band of guerillas launched a virtual insurrection against the Confederacy in Jefferson Davis’ own home state.
“There’s lots of ways I’d rather die than being scared to death,” Knight said, and it was a defining statement. At almost every stage of his life this yeoman from the hill country of Jones County, Miss., took courageous stands. The grandson of a slave owner who never owned slaves, he voted against secession, deserted from the Confederate Army into which he was unwillingly impressed, and formed a band called the Jones County Scouts devoted to undermining the Rebel cause locally. Working with runaway slaves and fellow Unionists and Federal soldiers caught behind enemy lines, Knight conducted such an effective running gun battle that at the height of the war he and his allies controlled the entire lower third of the state. This "southern Yankee,” as one Rebel general termed him, remained unconquered until the end of the war. His resistance hampered the Confederate Army’s ability to operate, forced it to conduct a third-front war at home, and eroded its morale and will to fight.
UPDATE: Apparently, there is a scholarly controversy over the matter.
