Read the excerpt from act 5, scene 1, of Julius Caesar.

MESSENGER. Prepare you, generals.
The enemy comes on in gallant show.
Their bloody sign of battle is hung out,
And something to be done immediately.

ANTONY. Octavius, lead your battle softly on,
Upon the left hand of the even field.

OCTAVIUS. Upon the right hand, I; keep thou the left.

How does the use of the word gallant add to the meaning of the sentence?

It suggests the enemy is planning a stealthy surprise attack on the enemy.
It shows that the enemy is in a weakened state and tired from the long trek.
It reveals that the enemy is distracted by the series of dark omens during their march to battle.
It suggests that the enemy is well-decorated and showy in their confident approach.
