In the great court-yard the leader of the English men-at-arms was placed with twelve of his men as a reserve. They were to be summoned by one, two, three, or four blasts of a horn to the point at which their services were most required. The assaults were obstinate, but the walls were as stoutly defended. Sometimes the ladders were hurled back by poles with an iron fork at the end; buckets of boiling water and tar were poured over on to the assailants as they clambered up, and lime cast over on those waiting to take their turns to ascend; while with spear, axe, and mace the men-at-arms and tenants met the assailants as they endeavoured to get a footing on the wall.
