Your swords won't break in the immediate fight where they receive the red stamp, they will just get pushed to the rear of the formation with 1HP left.

However, should you choose to continue with the sortie, they can and will break if struck, be it by anything if they have no troops left, or a Yari if they do. For this reason the game will give out a warning and prompt you to return to the citadel when a sword is in the red at the end of a fight.
