He commanded Company E in an attack against a reinforced enemy battalion which had held up the American advance for two days from its entrenched positions around a three-story concrete building. With another infantry company and armored vehicles, Company E advanced against heavy machine-gun and other automatic-weapon fire with Lt. Nett spearheading the assault against the strongpoint. During the fierce hand-to-hand encounter which ensued, he killed seven deeply entrenched Japanese with his rifle and bayonet and, although seriously wounded, gallantly continued to lead his men forward, refusing to relinquish his command. Again he was severely wounded, but, still unwilling to retire, pressed ahead with his troops to assure the capture of the objective. Wounded once more in the final assault, he calmly made all arrangements for the resumption of the advance, turned over his command to another officer, and then walked unaided to the rear for medical treatment. By his remarkable courage in continuing forward through sheer determination despite successive wounds, Lt. Nett provided an inspiring example for his men and was instrumental in the capture of a vital strongpoint.
