When you have posted knights to carry out this--and I need not say that the operation must be performed as silently as possible, for it is above all things necessary that the men concerned shall have no suspicion that their plot has been discovered--you will conduct other parties to the various rooms occupied by the slaves.

The guards on duty inside will be made prisoners.

The doors will then be locked and barred as before.

The appearance of the knights and the arrest of the guards will be sufficient to show the slaves that their plot has been discovered, and there will be no fear of their making any attempt to carry it into execution.

I will myself post the main body of the knights in the courtyard.
