eleven o'clock
Sometimes they went ahead at full speed for a few hundred yards , as if to chase an adversary ; then they would swerve aside , the slaves on one side rowing , while those on the other backed , so as to make a rapid turn . Then she lay for a minute or two immovable , and then backed water , or turned to avoid the attack of an imaginary foe . Then for an hour she lay quiet , while the knights , divesting themselves of their mantles and armour , worked one of the guns on the poop , aiming at a floating barrel moored for the purpose a mile out at sea . At eleven o'clock they returned to the port . Bread and water were served out to the slaves , and they were then permitted to lie down and sleep , the galley being moored under the shadow of the wall . At four o'clock another party of knights came down , and the work was similar to that which had been performed in the morning . At seven o'clock the slaves were taken back to their barracks .
