I vaguely remember an animated movie about a girl (maybe a princess) that acted like a tomboy or told everyone she was a boy. She had what I think was a fencing sword. In one scene she's running, jumps and grabs on to a beam sticking out of a wall and swings around and drops back down to the ground. I saw it when I was very young (84' maybe) and can only remember that. I really hope someone has seen it and can give me some information. Thanks!:)
