It's not a documentary style movie, describing the Battle of the Scheldt in detail. It is a story about young people's lives during in war. They did manage to reach the younger public with the story, at least here in The Netherlands. See

My son was an extra for two days, had great fun dressing up and during the shooting. Lots of waiting and hanging around, just like the real army
