Thus prepared for anything that may betide, they set out on the morrow to scale the city walls, rolling ahead of them their mighty engines of war, by means of which they hope to seize the city.
Most of the Crusaders have laid aside their heavy armor and assumed the light gear of foot-soldiers the better to scale the walls, upon which Clorinda is posted, and whence she shoots arrow after arrow at the assailants.
