There were no Confederates standing near it but several were lying down around it. Upon a call for volunteers by Major Ellis to capture this flag, this soldier and two others leaped the wall. One companion was instantly shot. Sgt. Maj. Hincks outran his remaining companion running straight and swift for the colors amid a storm of shot. Swinging his saber over the prostrate Confederates and uttering a terrific yell, he seized the flag and hastily returned to his lines. The 14th Tennessee carried twelve battle honors on its flag.
