Her ancient towers forsaken, while her youth, Some on the bounding steed, the tall bark some Ascending, some with painful march on foot, Haste on, to arrange the deep'ning files of war.
This passage evokes a sense of urgency and transition. It describes a scene where an ancient city or fortress is abandoned, and its youthful inhabitants are mobilizing for war. Some are riding horses, some are boarding ships, and others are marching on foot, all hastening to join and organize the ranks of the army. The imagery emphasizes both the decline of the old and the dynamic, decisive action of the new generation as they prepare for battle. CC BY-NC
