I remember seeing this movie on DVD in the mid-early 2000s, but it could have been made in the 90’s or probably the 80’s. I’m pretty sure it was in French, maybe it wasn’t, but it had this group of children who were playing war or something like that. They each had really cool forts, and it had something to do with Spanish conquistadors. In one scene, they are throwing mud at each other, but one kid puts rocks in his mud in order to injure the other side, and that is really bad. & then there is another part where some kids get leeches?  I’d like to see it again & I can’t remember the title or anything
