Answer: What In The World Happened Here? LXXXIX: (89)

This was the entrance to "Harry", the successful tunnel in the Great Escape. Paul Brickhill wrote the book. The movie starring Steve McQueen took a lot of liberties with the facts - at least as far as motorcycles were involved. Although only three tunnelers returned to England, the war effort in Germany was affected by the half a million soldiers and police required to conduct a search for the escapees. Fifty escapees were shot by the Nazis in cold blood. Stalag Luft III was evacuated on the anniversary of the posting.
