The Union blockaded the South, making it so trading ships couldn't come or go.
<em>I don´t understand why there is a fee</em> is a declarative sentence.The sentence states that there is something that is not understood.
For the sentence to be exclamatory it needs an exclamation mark at the end:
<em>I don´t understand why there is a fee is a declarative sentence !</em>
For this sentence to be interrogative, it needs a question mark at the end and an auxiliary before the main verb: <em>Do you understand why there is a fee?</em>
Finally, to be imperative, it needs the imperative structure that requires no subject:
Don´t understand why there is a fee is a declarative sentence! This last is really not a probable option in normal speech.
