The quarry lay at a distance of half a mile from the castle, and as fast as the stones were squared and roughly dressed they were taken in carts to the spot where they were to be used. Guy had the foundations for the walls dug in the first place, to a depth below that of the bottom of the moats, and filled up with cement and rubble. The trenches were then dug at a distance of five feet from the foot of the walls. With so many hands the work proceeded briskly, and before springtime the three works were all completed, with their bridges and ladders, passages pierced through the castle wall, and stone steps built inside by which those who passed through could either descend into the court yard or mount to the battlements. At the end of September fifteen archers and men-at-arms arrived from England to take the place of those who had desired to return home, and who on their coming marched away to Calais.
