Um..huh? It's similar to "Rememberance Day" in Canada. And as it isn't a well known day to many people outside of your area, I was asking, quite sincerely, is that the event that was depicited in a movie that crossed my mind.
No different then asking if Hamburger Hill in whatever movie was based on Vietnam.
I apologize if you were offended, because it was meant as a educational question.
