YOU HAVE LOST AN ARM!!! Too bad. Your attack on lar's arm stretched it out for him to do a twirling of his sword to take out your arm. You expected to get his, but he immediately turned the tables!
Bors gives a snicker of delight as he watches. You feel agitated by this dishonorable action by a marshal, but the fight must go on. There is no hold given for you to drop your shield and switch arms. Lars is attacking right as you get your sword to your left hand.
Quick! Hurry! A highly dishonorable attack is incoming! You can either try to defend from this heinous crime upon the art of boffer, or you can take his sorry, cheating, dishonorable butt out of the game with a lightning attack.
