He was probably OSS , and more than likely part of a Jedburgh team. Truly joint, fantastically brave people were in these small teams who advised and lead resistance organizations throughout Europe. Their fate , if captured ,was both gruesome and fatal.
Glenn Ford sent out letters in the last few years asking for donations for, I believe, Young Americans for Freedom, or some other college based association that supports education of patriotic values in our youth.
One of my favorite Glenn Ford movies is Cowboy with Jack Lemmon. Not to be confused with The Cowboys with John Wayne.
