“The days intervening from the 19th to the 22d were spent in one continued bombarding and sharpshooting during the day; in the night they generally ceased firing. On the morning of the 22d, the enemy opened a terrific fire with their Parrot guns, and continued it till about eleven o’clock, when the bombardment ceased, and heavy columns of the enemy could be seen forming in line of battle. Our forces were all ready for them, and eager for their advance. At about a quarter to twelve, the column of the Federal army advanced all along the lines in splendid order, and with a loud cheer dashed up to the works. They were gallantly responded to by our brave boys, and the first charge repulsed. On the extreme right of our lines, the nature of the ground prevented the enemy from making any heavy attack, but on the right of the centre, the centre, and the left of the centre, the assault was desperately made and gallantly met. But once did our lines break, and that was in Lee’s brigade. The enemy gained a temporary footing on the rifle-pits, but Lee quickly rallied his men, and, after a desperate hand-to-hand fight, drove them out and reoccupied the lines. The engagement at this point, and at the right of the line, held by Brigadier-General L. Herbert, was of a terrible nature, the Federals having thrown their best troops on these works. Five times did they charge, and each time were repulsed. The last charge on the right of Brigadier-General Herbert’s lines was made by an Irish regiment (the Seventeenth Wisconsin), carrying the green flag of Erin. They came at a double-quick up the hill, each man in the front ranks furnished with a ladder to reach the works. Three times they essayed to plant their ladders, but were prevented by the obstinate resistance offered by the consolidated Twenty-first and Twenty-third Louisiana regiments. At the third charge they came within ten yards of the line, but two volleys of buckshot from the shotguns of our forces compelled them to make a precipitate retreat from the front of our works. At about two o’clock they made their last charge, and were again repulsed, when they retired, and did not attempt any further demonstration that day. The loss of the enemy on that day is estimated by competent parties at not less than from eight to ten thousand, while our loss was between eight hundred and one thousand in killed and wounded.”
The following dispatch of Rear-Admiral Porter to the Secretary of the Navy, describes the part taken in this conflict by the naval force:
Mississippi Squadron, Flagship Black Hawk, }
May 23, 1863. }
Sir—On the morning of the 21st I received a communication from General Grant, informing me that he intended to attack the whole of the rebel works at ten A. M. the next day, and asking me to shell the batteries from half-past nine until half-past ten, and to annoy the garrison. I kept six mortars playing rapidly on the works and town all night, and sent the Benton, Mound City and Carondolet up to shell the water batteries and other places where troops might be resting during the night. At seven o’clock in the morning, the Mound City proceeded across the river, and made an attack on the hill batteries opposite the canal. At eight o’clock I found her in company with the Benton, Tuscumbia, and Carondolet. All these vessels opened on the hill batteries, and finally silenced them, though the main work on the battery containing the heavy rifled gun was done by the Mound City, Lieutenant Commanding Byron Wilson. I then pushed the Benton, Mound City and Carondolet up to the water batteries, leaving the Tuscumbia, which is still out of repair, to keep the hill batteries from firing on our vessels after they had passed by. The three gunboats passed up slowly, owing to the strong current, the Mound City leading, the Benton following, and the Carondolet astern. The water batteries opened furiously, supported by a hill battery on the starboard beam of the vessels. The vessels advanced to within four hundred and forty yards (by our marks) and returned the fire for two hours without cessation, the enemy’s fire being very accurate and incessant.
Finding that the hill batteries behind us were silenced, I ordered up the Tuscumbia to within eight hundred yards of the batteries; but the turret was soon made untenable, not standing the enemy’s shot, and I made her drop down. I had been engaged with the forts an hour longer than General Grant asked. The vessels had all received severe shots under water which we could not stop while in motion, and not knowing what might have delayed the movement of the army, I ordered the vessels to drop out of fire, which they did in a cool, handsome manner.
This was the hottest fire the gunboats had ever been under; but, owing to the water batteries being more on a level with them than usual, the gunboats threw in their shell so fast that the aim of the enemy was not very good. The enemy hit our vessels a number of times, but fighting bow on, they did but little damage.
Not a man was killed, and only a few wounded. I had only enough ammunition for a few moments longer, and set all hands to work to fill up from our depot below.
After dropping back I found that the enemy had taken possession again of one of the lower hill batteries and was endeavoring to mount his guns, and had mounted a 12-pounder field piece to fire at General McArthur’s troops, which had landed a short time before at Warrenton. I sent the Mound City and Carondolet to drive him off, which they did in a few moments.
I beg leave to enclose a letter from General McArthur, explaining why he did not (to use his own expression), take advantage of the results gained by the gunboats. I have since learned through General Grant that the army did assault at the right time vigorously. In the noise and smoke we could not see or hear it. The gunboats were, therefore, still fighting when the assault had proved unsuccessful.
