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.
There is a long tongue of land from the Louisiana side extending towards
Grand Gulf, made by the river running nearly east from about three miles
above and nearly in the opposite direction from that point for about the
same distance below. The land was so low and wet that it would not have
been practicable to march an army across but for a levee. I had had
this explored before, as well as the east bank below to ascertain if
there was a possible point of debarkation north of Rodney. It was found
that the top of the levee afforded a good road to march upon.
Porter, as was always the case with him, not only acquiesced in the
plan, but volunteered to use his entire fleet as transports. I had
intended to make this request, but he anticipated me. At dusk, when
concealed from the view of the enemy at Grand Gulf, McClernand landed
his command on the west bank. The navy and transports ran the batteries
successfully. The troops marched across the point of land under cover of
night, unobserved. By the time it was light the enemy saw our whole
fleet, ironclads, gunboats, river steamers and barges, quietly moving
down the river three miles below them, black, or rather blue, with
National troops.
When the troops debarked, the evening of the 29th, it was expected that
we would have to go to Rodney, about nine miles below, to find a
landing; but that night a colored man came in who informed me that a
good landing would be found at Bruinsburg, a few miles above Rodney,
from which point there was a good road leading to Port Gibson some
twelve miles in the interior. The information was found correct, and
our landing was effected without opposition.
Sherman had not left his position above Vicksburg yet. On the morning
of the 27th I ordered him to create a diversion by moving his corps up
the Yazoo and threatening an attack on Haines' Bluff.
My object was to compel Pemberton to keep as much force about Vicksburg
as I could, until I could secure a good footing on high land east of the
river. The move was eminently successful and, as we afterwards learned,
created great confusion about Vicksburg and doubts about our real
design. Sherman moved the day of our attack on Grand Gulf, the 29th,
with ten regiments of his command and eight gunboats which Porter had
left above Vicksburg.
He debarked his troops and apparently made every preparation to attack
the enemy while the navy bombarded the main forts at Haines' Bluff.
This move was made without a single casualty in either branch of the
service. On the first of May Sherman received orders from me (sent from
Hard Times the evening of the 29th of April) to withdraw from the front
of Haines' Bluff and follow McPherson with two divisions as fast as he
could.
I had established a depot of supplies at Perkins' plantation. Now that
all our gunboats were below Grand Gulf it was possible that the enemy
might fit out boats in the Big Black with improvised armament and
attempt to destroy these supplies. McPherson was at Hard Times with a
portion of his corps, and the depot was protected by a part of his
command. The night of the 29th I directed him to arm one of the
transports with artillery and send it up to Perkins' plantation as a
guard; and also to have the siege guns we had brought along moved there
and put in position.
The embarkation below Grand Gulf took place at De Shroon's, Louisiana,
six miles above Bruinsburg, Mississippi. Early on the morning of 30th
of April McClernand's corps and one division of McPherson's corps were
speedily landed.
When this was effected I felt a degree of relief scarcely ever equalled
since. Vicksburg was not yet taken it is true, nor were its defenders
demoralized by any of our previous moves. I was now in the enemy's
country, with a vast river and the stronghold of Vicksburg between me
and my base of supplies. But I was on dry ground on the same side of
the river with the enemy. All the campaigns, labors, hardships and
exposures from the month of December previous to this time that had been
made and endured, were for the accomplishment of this one object.
I had with me the 13th corps, General McClernand commanding, and two
brigades of Logan's division of the 17th corps, General McPherson
commanding--in all not more than twenty thousand men to commence the
campaign with. These were soon reinforced by the remaining brigade of
Logan's division and Crocker's division of the 17th corps. On the 7th
of May I was further reinforced by Sherman with two divisions of his,
the 15th corps. My total force was then about thirty-three thousand
men.
The enemy occupied Grand Gulf, Haines' Bluff and Jackson with a force of
nearly sixty thousand men. Jackson is fifty miles east of Vicksburg and
is connected with it by a railroad. My first problem was to capture
Grand Gulf to use as a base.
Bruinsburg is two miles from high ground. The bottom at that point is
higher than most of the low land in the valley of the Mississippi, and a
good road leads to the bluff. It was natural to expect the garrison
from Grand Gulf to come out to meet us and prevent, if they could, our
reaching this solid base. Bayou Pierre enters the Mississippi just
above Bruinsburg and, as it is a navigable stream and was high at the
time, in order to intercept us they had to go by Port Gibson, the
nearest point where there was a bridge to cross upon. This more than
doubled the distance from Grand Gulf to the high land back of
Bruinsburg. No time was to be lost in securing this foothold. Our
transportation was not sufficient to move all the army across the river
at one trip, or even two; but the landing of the 13th corps and one
division of the 17th was effected during the day, April 30th, and early
evening. McClernand was advanced as soon as ammunition and two days'
rations (to last five) could be issued to his men. The bluffs were
reached an hour before sunset and McClernand was pushed on, hoping to
reach Port Gibson and save the bridge spanning the Bayou Pierre before
the enemy could get there; for crossing a stream in the presence of an
enemy is always difficult. Port Gibson, too, is the starting point of
roads to Grand Gulf, Vicksburg and Jackson.
McClernand's advance met the enemy about five miles west of Port Gibson
at Thompson's plantation. There was some firing during the night, but
nothing rising to the dignity of a battle until daylight. The enemy had
taken a strong natural position with most of the Grand Gulf garrison,
numbering about seven or eight thousand men, under General Bowen. His
hope was to hold me in check until reinforcements under Loring could
reach him from Vicksburg; but Loring did not come in time to render much
assistance south of Port Gibson. Two brigades of McPherson's corps
followed McClernand as fast as rations and ammunition could be issued,
and were ready to take position upon the battlefield whenever the 13th
corps could be got out of the way.
The country in this part of Mississippi stands on edge, as it were, the
roads running along the ridges except when they occasionally pass from
one ridge to another. Where there are no clearings the sides of the
hills are covered with a very heavy growth of timber and with
undergrowth, and the ravines are filled with vines and canebrakes,
almost impenetrable. This makes it easy for an inferior force to delay,
if not defeat, a far superior one.
Near the point selected by Bowen to defend, the road to Port Gibson
divides, taking two ridges which do not diverge more than a mile or two
at the widest point. These roads unite just outside the town. This
made it necessary for McClernand to divide his force. It was not only
divided, but it was separated by a deep ravine of the character above
described. One flank could not reinforce the other except by marching
back to the junction of the roads. McClernand put the divisions of
Hovey, Carr and A. J. Smith upon the right-hand branch and Osterhaus on
the left. I was on the field by ten A.M., and inspected both flanks in
person. On the right the enemy, if not being pressed back, was at least
not repulsing our advance. On the left, however, Osterhaus was not
faring so well. He had been repulsed with some loss. As soon as the
road could be cleared of McClernand's troops I ordered up McPherson, who
was close upon the rear of the 13th corps, with two brigades of Logan's
division. This was about noon. I ordered him to send one brigade
(General John E. Smith's was selected) to support Osterhaus, and to move
to the left and flank the enemy out of his position. This movement
carried the brigade over a deep ravine to a third ridge and, when
Smith's troops were seen well through the ravine, Osterhaus was directed
to renew his front attack. It was successful and unattended by heavy
loss. The enemy was sent in full retreat on their right, and their left
followed before sunset. While the movement to our left was going on,
McClernand, who was with his right flank, sent me frequent requests for
reinforcements, although the force with him was not being pressed. I
had been upon the ground and knew it did not admit of his engaging all
the men he had. We followed up our victory until night overtook us
about two miles from Port Gibson; then the troops went into bivouac for
the night.
