After 2 days of intense physical and mental strain, during which Maj. Miller had led his battalion in the front line of the advance through the forest of Argonne, the enemy was met in a prepared position south of Gesnes. Though almost exhausted, he energetically reorganized his battalion and ordered an attack. Upon reaching open ground the advancing line began to waver in the face of machinegun fire from the front and flanks and direct artillery fire. Personally leading his command group forward between his front-line companies, Maj. Miller inspired his men by his personal courage, and they again pressed on toward the hostile position. As this officer led the renewed attack he was shot in the right leg, but he nevertheless staggered forward at the head of his command. Soon afterwards he was again shot in the right arm, but he continued the charge, personally cheering his troops on through the heavy machinegun fire. Just before the objective was reached he received a wound in the abdomen, which forced him to the ground, but he continued to urge his men on, telling them to push on to the next ridge and leave him where he lay. He died from his wounds a few days later.
