After the fall of the Philippines, Lieutenant Commander Davis was interned at the infamous prisoner-of-war camp at Cabanatuan. As a P.O.W. he built a powerful underground organization to obtain food, medicines and communications of all kinds. He volunteered for command of a firewood detail, and despite the constant surveillance of Japanese guards, succeeded in smuggling into camp tremendous amounts of food and other necessities to his fellow prisoners. His great personal valor and grave concern for others at a great risk to his own life contributed to the welfare and morale of all prisoners on Luzon and saved countless lives before he died December 14, 1944.
