ATTACK ON GRAND GULF--OPERATIONS BELOW VICKSBURG.
On the 24th my headquarters were with the advance at Perkins' plantation. Reconnoissances were made in boats to ascertain whether there was high land on the east shore of the river where we might land above Grand Gulf. There was none practicable.
Accordingly the troops were set in motion for Hard Times, twenty-two miles farther down the river and nearly opposite Grand Gulf. The loss of two steamers and six barges reduced our transportation so that only 10,000 men could be moved by water.
Some of the steamers that had got below were injured in their machinery, so that they were only useful as barges towed by those less severely injured. All the troops, therefore, except what could be transported in one trip, had to march. The road lay west of Lake St. Joseph. Three large bayous had to be crossed. They were rapidly bridged in the same manner as those previously encountered. (*12)
On the 27th McClernand's corps was all at Hard Times, and McPherson's was following closely. I had determined to make the attempt to effect a landing on the east side of the river as soon as possible. Accordingly, on the morning of the 29th, McClernand was directed to embark all the troops from his corps that our transports and barges could carry. About 10,000 men were so embarked. The plan was to have the navy silence the guns at Grand Gulf, and to have as many men as possible ready to debark in the shortest possible time under cover of the fire of the navy and carry the works by storm. The following order was issued:
PERKINS PLANTATION, LA., April 27,1863.
MAJOR-GENERAL J. A. MCCLERNAND, Commanding 13th A. C.
Commence immediately the embarkation of your corps, or so much of it as there is transportation for. Have put aboard the artillery and every article authorized in orders limiting baggage, except the men, and hold them in readiness, with their places assigned, to be moved at a moment's warning.
All the troops you may have, except those ordered to remain behind, send to a point nearly opposite Grand Gulf, where you see, by special orders of this date, General McPherson is ordered to send one division.
The plan of the attack will be for the navy to attack and silence all the batteries commanding the river. Your corps will be on the river, ready to run to and debark on the nearest eligible land below the promontory first brought to view passing down the river. Once on shore, have each commander instructed beforehand to form his men the best the ground will admit of, and take possession of the most commanding points, but avoid separating your command so that it cannot support itself. The first object is to get a foothold where our troops can maintain themselves until such time as preparations can be made and troops collected for a forward movement.
Admiral Porter has proposed to place his boats in the position indicated to you a few days ago, and to bring over with them such troops as may be below the city after the guns of the enemy are silenced.
It may be that the enemy will occupy positions back from the city, out of range of the gunboats, so as to make it desirable to run past Grand Gulf and land at Rodney. In case this should prove the plan, a signal will be arranged and you duly informed, when the transports are to start with this view. Or, it may be expedient for the boats to run past, but not the men. In this case, then, the transports would have to be brought back to where the men could land and move by forced marches to below Grand Gulf, re-embark rapidly and proceed to the latter place.
There will be required, then, three signals; one, to indicate that the transports can run down and debark the troops at Grand Gulf; one, that the transports can run by without the troops; and the last, that the transports can run by with the troops on board.
Should the men have to march, all baggage and artillery will be left to run the blockade.
If not already directed, require your men to keep three days' rations in their haversacks, not to be touched until a movement commences.
U. S. GRANT, Major-General.
At 8 o'clock A.M., 29th, Porter made the attack with his entire strength present, eight gunboats. For nearly five and a half hours the attack was kept up without silencing a single gun of the enemy. All this time McClernand's 10,000 men were huddled together on the transports in the stream ready to attempt a landing if signalled. I occupied a tug from which I could see the effect of the battle on both sides, within range of the enemy's guns; but a small tug, without armament, was not calculated to attract the fire of batteries while they were being assailed themselves. About half-past one the fleet withdrew, seeing their efforts were entirely unavailing. The enemy ceased firing as soon as we withdrew. I immediately signalled the Admiral and went aboard his ship. The navy lost in this engagement eighteen killed and fifty-six wounded. A large proportion of these were of the crew of the flagship, and most of those from a single shell which penetrated the ship's side and exploded between decks where the men were working their guns. The sight of the mangled and dying men which met my eye as I boarded the ship was sickening.
Grand Gulf is on a high bluff where the river runs at the very foot of it. It is as defensible upon its front as Vicksburg and, at that time, would have been just as impossible to capture by a front attack. I therefore requested Porter to run the batteries with his fleet that night, and to take charge of the transports, all of which would be wanted below.
