On leaving the room he was again taken charge of by Captain do Courcy and four of his troopers, and was conducted by him to the citadel.
The quarters assigned to Jack were by no means uncomfortable.

A good meal was placed before him, and after he had finished it the governor of the citadel called upon him and told him that he was at liberty to go where he would within the walls, and that any wishes he might express he would do his best to comply with.

Jack at once availed himself of his liberty by going out into the courtyard and thence on to the walls of the citadel.

It was a strongly fortified and gloomy building, which has now ceased to exist.

It covered a considerable portion of ground, and had at one time been a royal residence; the walls were strong and high, and sentries were placed on them at short intervals.
Jack saw at once there was little possibility of escape thence, and decided that he might as well abandon any idea of evasion for the present, and would trust to luck in escaping from his escort on the road to the frontier, or, if no opportunity then presented itself, from his prison in France.
