As soon as the king's army approached Arras, Guy repeated all the precautions that had before been taken, but as this time there had been long warning, these were carried out more effectually. A considerable number of the cattle and sheep of the tenants were driven to Calais and there sold, the rest, with the horses, were taken into the castle. The crops were hastily got in, for it was near July, and these were thrashed and the grain brought in, with the household furniture and all belongings. A great store of arrows had been long before prepared, and Guy felt confident that he could hold out for a long time. The women and children took up their abode in the castle, and the former were all set to work to make a great number of sacks. A hundred cart-loads of earth were brought in, and this was stored in a corner of the court-yard. The earth was to be employed in filling the sacks, which were to be lowered from the walls so as to form a protection against heavy missiles, should an attempt be made to effect a breach.
