On the 10th of January, the land forces, under command of General McClernand, and the flotilla, under Admiral Porter, ascended the river, and the former disembarked with a view of surrounding the work. During the night, the gunboats fired a few shots at the work, and in the morning, the troops being in position, the work commenced in earnest. The _New York Herald_ correspondent thus describes the attack: THE BOMBARDMENT. It was five minutes past one when the gunboats Baron DeKalb, Cincinnati, and Louisville, all iron-clads, steamed up to within about three hundred yards of the fort, and opened fire upon it. As soon as the gunboats hove in sight, and before they fired a shot, the fort opened on them. On a sort of sandy beach, by the bend in the river, the rebels had erected several targets, which were to assist them in aiming at the gunboats. Barricades had also been placed in the river opposite the fort; but the high water had washed part of them away and left the channel open. The bombardment increased in rapidity as other vessels of the squadron came into position. It took some time to get good range of the casemated guns and the barbette gun on the fort. The Baron DeKalb had orders from the Admiral to fire at the right hand casemate, the Louisville at the middle one, and the Cincinnati at the great 9-inch Dahlgren gun _en barbette_. In half an hour after the bombardment commenced the casemates were struck by the shell from the gunboats. When the range was obtained, the shells from the gunboats struck the guns in the fort almost every shot, until every one was silenced and smashed. The Cincinnati fired shrapnell at first, and cleared the crew away from the 9-inch Dahlgren gun on the parapet, when the Baron De Kalb broke off the muzzle with a 10-inch shot. The Lexington, light draught, Lieutenant-Commander James W. Shirk, moved up at two o’clock, and with her rifled guns replied to the Parrott rifled guns in the fort, while the Rattler, Lieutenant-Commander Walter Smith, and the Gilde, Lieutenant-Commander Woodworth, threw in shrapnell, and in company with the ram Monarch, Colonel Charles E. Ellet, of the army, commanding, pushed up close to the fort. Each of the gunboats silenced the gun it was instructed to fire at about the same time. At twenty minutes past two all the heavy smooth bore and rifled guns in the fort were most effectually silenced. The Black Hawk, Lieutenant-Commander K. R. Breese, the Admiral’s flagship, steamed up and took part in the fight. The Admiral himself, with his secretary, Doctor Heap, was in the little tug which was all the time screaming and dancing about among the gunboats, directing and superintending the fight. THE LAND ATTACK. The first gun from the fleet was the signal for the soldiers to move, and Morgan and Sherman immediately pushed forward their men, and were met by a fierce fire from the rebel works.
