Good night." At eight o'clock, having had a bowl of broth, Charlie descended to the courtyard in charge of an officer and two soldiers, the doctor accompanying him.

"I have the czar's commands," the Russian went on, "to express his regret that, owing to a mistake on the part of the officer commanding here, Ensign Carstairs has not received such worthy treatment as the czar would have desired for him, but he has given stringent orders that, in future, any Swedish officers who may be taken prisoners shall receive every comfort and hospitality that can be shown them."
