More than 35 Marine officers and a considerable number of enlisted Marines were assigned to duty with the OSS in Africa and Europe during the war. Their duties were so highly secret that even their award citations were classified and remained so until after the war.

All but four of the 2,274 Marines who became prisoners of war in World War II were taken by the Japanese. The known exceptions were Marines assigned to the Office of Strategic Services, better known as the OSS, who were captured in 1944 by German forces while engaged in covert activities in company with the French underground.

A veteran of the legendary French Foreign Legion before joining the Marine Corps, the tall, handsome Ortiz emerged from the war as the most decorated U.S. soldier to serve with the OSS. He was a courteous, compassionate man, and his fearlessness amazed all who knew him.
