Remembering Medal of Honor recipient Hershel "Woody" Williams

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. In this "Sunday Morning" profile that originally aired on May 30, 2021, Williams (who died on June 29 at the age of 98) talked with CBS News national security correspondent David Martin about his efforts for Gold Star families.
