A Medal of Honor recipient's continued service
During the Battle of Iwo Jima, in the face of powerful enemy resistance, Marine Cpl. Hershel "Woody" Williams succeeded in destroying several heavily-defended machine-gun pillboxes, and was awarded the Medal of Honor. But his service to his country, and his gallantry, did not end there. CBS News national security correspondent David Martin talked with the 97-year-old Williams, the last surviving Medal of Honor recipient from World War II, about his continuing efforts for Gold Star families.
