Strange Title ????

More sorting out books  today- found this book of Mazes by Vladimir Koziakin.
Now I m not very keen on puzzles but the title of this one caught my eye - Dien Bien Phu - why that is the title I have no idea . ??( Rated time limit 45 mins !!!!- it would take me hours !)
Dien Bien Phu - Concert de l'adieu
Dien Bien Phu was a battle in Indochine in the 1950's when the French were beaten and taken prisoner by the Vietminh . A film  about it was made in the 1990s and includes music by one of my favourite composers Georges Delerue.Well -that's what I was thinking about when I saw this strange title.
