Answer:
What is that which the breeze . . . half conceals, half discloses?"
Step-by-step explanation:
In these lines, the author expresses wonder and confusion as to what is still present. He tells us that he is trying to see something, but that the object is half concealed, and half-disclosed. The effect of this statement is to give the reader the same sense of wonder and suspense that the author feels when tying to discover what happened after the battle.
