Colonel Russell W. Volckmann was a lean West Pointer from Iowa. When Bataan fell in 1942 he took to the hills and organized one of the best guerrilla teams in the Philippines. By the time the U.S. forces came back, Volckmann and his band had already cleared the Japs from a large portion of northwestern Luzon's mountains.

United States Forces in the Philippines--Northern Luzon (USFIP-NL). Organized by Major (guerrilla Colonel) Russell Volckmann, USFIP-NL became one of the largest and best organized guerrilla operations on Luzon, and one of the most ruthless. In August 1943, when Capt. Ralph Praeger was captured, Volckmann took over his North Luzon Military District. In November 1943 Volckmann took over the remnants of Capt. Guillermo Nakar's 14th Infantry after Nakar was captured. In August 1944 he made radio contact with General MacArthur's headquarters, and in the fall of 1944 received 35 tons of supplies brought in by the submarine Seawolf. On January 9, 1945, Volckmann and his men met General MacArthur's invading forces on the beaches of Lingayen Gulf.
