In a few minutes the castle resounded with the din of preparations under the superintendence of Sir Eustace. The men-at-arms and archers carried up stones from the great pile that had been collected in the court-yard in readiness, to the various points on the walls that would be most exposed to assault. Others were employed in fixing barricades in the court-yard at the rear for the reception of the herd of half-wild cattle. The water was turned from the little rivulet running down to the Somme into the moat. Two or three bullocks were killed to furnish food for the fugitives who might come in, and straw was laid down thickly in the sheds that would be occupied by them. Machines for casting heavy stones were taken from the storehouse and carried up to the walls, and set up there. Large stone troughs placed in the court-yard were filled with water, and before nightfall everything was in readiness.
