From Fredericksburg — the firing at Port Royal.
--From passengers by the Fredericksburg train yesterday evening, we give an explanation of the firing at Port Royal Wednesday morning. The Yankees, with six pieces of artillery, supported by infantry, appeared on the bank of the river opposite Port Royal Wednesday morning, at an early hour, and opened fire on the Satellite and Reliance, the two captured steamers lying at the wharf there. They put a half dozen balls into the Satellite, and one or two into the Reliance. The fire was replied to by our men from three guns, (some say one gun, mounted on wheels,) which had been taken from the steamers. The Yankees retired after finding their efforts to destroy the vessels ineffectual.All the guns, machinery, and furniture of the two steamers had been removed from them before the attack by the Yankees, so that very little damage was done by the cannonading. No one on our side was hurt by the enemy's shells.
