It’s a cartoon movie I watched as a kid in the early 80’s but I think it was made earlier than that. It’s about a girl, maybe in Germany, who’s family gets taken by the Nazis and she hides in a hole in the woods that they had dug to hide in. She makes friends with a mouse and eventually an injured gestapo dog. I remember her counting out her matches each day. I don’t remember much else. I remember Vivaldi’s Four Seasons played in it at some point. That music reminds me of that movie to this day.
