CBC8 - Light Brigade characters: Capt Nolan, Capt Morris, 'Butcher Jack'
Captain Louis Nolan of the 15th Hussars was ADC to General Airey, and delivered the order that produced one of the most famous actions in all of military history.
Jack Vahey, regimental butcher of the 17th Lancers, spent the night before Balaclava under guard because of over-indulging in commissariat rum, but the next morning he took part in the Charge of the Light Brigade in his bloody overalls, wielding a butchers axe and riding a captured Russian officer's horse.
Captain William Morris was in the front rank during the Charge, and was one of the first horsemen to reach the Russian guns. Having taken command of the 17th Lancers only days before the charge, he was still wearing his forage cap.
