borhood. Beside the smaller courts inclosed by the buildings, a larger yard appears to have been formed by a stout wall, within which the allies had erected temporary shelter. This was the weakest point, and here the battering parties were chiefly collected. The flanks and curtains of modern fortification were wanting, and the protection of the wall face depended on the turrets which rose here and there, and on the parapets, with their few embrasures.
Though attempting no sortie beyond the immediate vicinity of the gates, the Spaniards were not sparing of powder and arrows, and picked off the more presumptuous assailants, while their pikes and swords did good service at the parapets and openings.
