Whats the Errol Flynn movie?

The scene is that I remember is he is a knight, riding with a group.
He comes upon a town, a maiden is in a tower and drops her glove, he
spears it with his lance and returns it to her. He is actually a
nobleman but doesn't want her to know and of course they fall in love.

If you remember the scene . . . What's the name of the movie?
