is the sentence narrative, exposition, description, or persuasive? They tell us, sir, that we are weak; unable to cope with so formidable an adversary. But when shall we be stronger? Will it be the next week, or the next year? Will it be when we are totally disarmed? . . . I know not what course others may take; but as for me, give me liberty or give me death!

The sentence is persuasive.
