When the barbican was carried, the Sable Knight sent notice of the happy event to Locksley, requesting him at the same time, to keep such a strict observation on the castle as might prevent the defenders from combining their force for a sudden sally, and recovering the outwork which they had lost. This the knight was chiefly desirous of avoiding, conscious that the men whom he led, being hasty and untrained volunteers, imperfectly armed and unaccustomed to discipline, must, upon any sudden attack, fight at great disadvantage with the veteran soldiers of the Norman knights, who were well provided with arms both defensive and offensive; and who, to match the zeal and high spirit of the besiegers, had all the confidence which arises from perfect discipline and the habitual use of weapons.

The knight employed the interval in causing to be constructed a sort of floating bridge, or long raft, by means of which he hoped to cross the moat in despite of the resistance of the enemy. This was a work of some time, which the leaders the less regretted, as it gave Ulrica leisure to execute her plan of diversion in their favour, whatever that might be.
