Thus ranges eager Turnus o'er the plain,
Sharp with desire, and furious with disdain;
Surveys each passage with a piercing sight,
To force his foes in equal field to fight.
Thus while he gazes round, at length he spies,
Where, fenced with strong redoubts, their navy lies.
Close underneath the walls: the washing tide
Secures from all approach this weaker side.
He takes the wished occasion, fills his hand
With ready fires, and shakes a flaming brand.
