Powerful. Full of power; capable of producing great effects of any kind; as, a powerful army or navy.

Pozzuoli. A city of Southern Italy, at the east of the Bay of Naples. It is first mentioned in history during the second Punic war, when it was surrounded by strong walls.

It was afterwards rebuilt by the Byzantine Greeks, but being exposed to new devastations, to earthquakes, and volcanic eruptions, it sank into decay.

Practicable. A word frequently used in military matters to express the possible accomplishment of any object. Hence, a practicable breach.
