Read these lines from the poem.
A phantom ship, with each mast and spar
Across the moon like a prison-bar,
And a huge black hulk, that was magnified
By its own reflection in the tide.
What is the effect of the description of the British ship?
It reveals the threat of a new enemy.
It connects the reader to the sailors on the ship.
It suggests the enemy ships are imaginary.
It hints that there is danger coming.
