The morning was clear and beautiful, but not calm. A stiff breeze came from the East, as if to bear the terrific reports of the cannonading to Savannah, whose distant spires and towers gleamed in the sun. Our blockading fleet, with accompanying transports, lay at anchor in Tybee harbor. Here and there a gunboat, firing occasional shots, could be seen moving about in Wilmington sound, while the Unadilla, Hale, and Western World occupied their positions in Wright and Mud rivers. Tatnall's fleet was no where to be seen, and all things in the direction of Savannah seemed as quiet as though that city was peacefully and securely reposing, as in other days, under the broad folds of the American Union. It was a sad and woful day to the cities of the South, when her rebel princes renounced their allegiance to the government, and raised the traitor arm of rebellion against its authority. Imagined evils, in connection with the Union, were then converted into real ones, and these have been augmented a thousand-fold in the severance from that Union. When the South shall 'come to herself'--if she ever does--like the prodigal son, she will find her condition quite as pitiable, and in rags and wretchedness, she will seek her father's house, willing, no doubt, to occupy a servant's place in the national household. Nor until true and genuine repentance shall come to her, can she hope for a father's forgiveness and a prodigal's reception and restoration. Boom! boom!! boom!!! as if the last great day of vengeance had come, and you could hear the screeching of a thousand fiends in the air hastening to their destiny, come upon the ear, as Tybee utters her thunders, and pours out her vials of wrath. See that cloud of dust which shoots up like a volcano, and looks as though the whole east side of the fort had fallen in! Bolts of iron, like winged battering-rams, are ploughing fearfully through her belabored side. Before this cloud has passed away, you see, just above it, another, not dark and angry, but in appearance white and spherical as the moon. A shell has exploded, and rained its iron fragments into the fort.
