Once you demolish the banner, your armor should revert to normal. (Because once you destroy the banner, your true alligiance would be shown.)

And getting out of a fortress in chain armour might not be as simple as thought. To be effective, you might want a second player attacking to create a diversion. (A better name for the spy would be saboteur.)
