Received the Distinguished Service Cross (1943) for extraordinary heroism in connection with military operations against an armed enemy while Commanding the Mindanao-Visayan Force (Philippine Guerillas), in action against enemy forces from 8 May 1943 to 6 August 1943, in the Philippine Islands. Refusing to surrender when the major defense forces were overcome, Colonel Fertig assumed command of scattered forces continuing resistance on the island of Mindanao. He effectively organized many dispersed elements throughout the island, held much stronger enemy forces continuously at bay, and denied to them some of the resources of their country. He improvised tactics for effective warfare with limited means, and ingenious methods for supplying his men and their families. He persisted in this enterprise, although a large price was set on his head, and he was of necessity in constant proximity to the enemy. His courage and resourcefulness enabled him to avoid capture, to inspire in the people of Mindanao a will to resist, and to furnish the United States Command with information of great military value.
