Their ranks grow smaller every year so only a handful of Pearl Harbor survivors will attended ceremonies on Tuesday near the Capitol in St. Paul.  On December 7th, 1941, Dick Thill of St. Paul was an 18-year-old Navy reservist when his ship sank a Japanese mini submarine an hour before the air raid on the big Hawaiian naval base.  After the war, Thill met the commander of another mini-sub who said he could have sent Thill's ship to the bottom that morning.  U.S. and state flags are flying at half staff in memory of the hundreds of civilians and military personnel killed at Pearl Harbor 69 years ago.
