I watched this film quite a few years ago and I don’t remember much about it, just a scene that is really vivid in my mind.
Two children, a brother and sister, i think are brought out from hiding in their hut or cave and murdered by a group of soldiers with bayonets. They’re all white in my memory and I think the girl had blonde hair. I don’t know what country or era the soldiers are from but they look a little like French revolution soldiers or early American civil war. I think the little girls tries to comfort her little brother before they kill them. The children are very young perhaps 5 and 9?
The film seemed like it was made in the 60s and I saw it when I was a child and I am 22 now.
The only match I can think of is Hannibal Rising, which has sort of an “old movie” feel to it, but is from 2007. Good luck!
