My line was more than fifteen miles long, extending from Haines" Bluff to Vicksburg, thence to Warrenton. The line of the enemy was about seven. In addition to this, having an enemy at Canton and Jackson, in our rear, who was being constantly reinforced, we required a second line of defence facing the other way. I had not troops enough under my command to man these. General Halleck appreciated the situation and, without being asked, forwarded reinforcements with all possible dispatch.
The ground about Vicksburg is admirable for defence. On the north it is about two hundred feet above the Mississippi River at the highest point and very much cut up by the washing rains; the ravines were grown up with cane and underbrush, while the sides and tops were covered with a dense forest. Farther south the ground flattens out somewhat, and was in cultivation. But here, too, it was cut up by ravines and small streams. The enemy"s line of defence followed the crest of a ridge from the river north of the city eastward, then southerly around to the Jackson road, full three miles back of the city; thence in a southwesterly direction to the river. Deep ravines of the description given lay in front of these defences. As there is a succession of gullies, cut out by rains along the side of the ridge, the line was necessarily very irregular. To follow each of these spurs with intrenchments, so as to command the slopes on either side, would have lengthened their line very much. Generally therefore, or in many places, their line would run from near the head of one gully nearly straight to the head of another, and an outer work triangular in shape, generally open in the rear, was thrown up on the point; with a few men in this outer work they commanded the approaches to the main line completely.
The work to be done, to make our position as strong against the enemy as his was against us, was very great. The problem was also complicated by our wanting our line as near that of the enemy as possible. We had but four engineer officers with us. Captain Prime, of the Engineer Corps, was the chief, and the work at the beginning was mainly directed by him.
His health soon gave out, when he was succeeded by Captain Comstock, also of the Engineer Corps. To provide a.s.sistants on such a long line I directed that all officers who had graduated at West Point, where they had necessarily to study military engineering, should in addition to their other duties a.s.sist in the work.
The chief quartermaster and the chief commissary were graduates. The chief commissary, now the Commissary-General of the Army, begged off, however, saying that there was nothing in engineering that he was good for unless he would do for a sap-roller. As soldiers require rations while working in the ditches as well as when marching and fighting, and as we would be sure to lose him if he was used as a sap-roller, I let him off. The general is a large man; weighs two hundred and twenty pounds, and is not tall.
We had no siege guns except six thirty-two pounders, and there were none at the West to draw from. Admiral Porter, however, supplied us with a battery of navy-guns of large calibre, and with these, and the field artillery used in the campaign, the siege began. The first thing to do was to get the artillery in batteries where they would occupy commanding positions; then establish the camps, under cover from the fire of the enemy but as near up as possible; and then construct rifle-pits and covered ways, to connect the entire command by the shortest route. The enemy did not hara.s.s us much while we were constructing our batteries.
Probably their artillery ammunition was short; and their infantry was kept down by our sharpshooters, who were always on the alert and ready to fire at a head whenever it showed itself above the rebel works.
In no place were our lines more than six hundred yards from the enemy.
It was necessary, therefore, to cover our men by something more than the ordinary parapet. To give additional protection sand bags, bullet-proof, were placed along the tops of the parapets far enough apart to make loop-holes for musketry. On top of these, logs were put.
By these means the men were enabled to walk about erect when off duty, without fear of annoyance from sharpshooters. The enemy used in their defence explosive musket-b.a.l.l.s, no doubt thinking that, bursting over our men in the trenches, they would do some execution; but I do not remember a single case where a man was injured by a piece of one of these sh.e.l.ls. When they were hit and the ball exploded, the wound was terrible. In these cases a solid ball would have hit as well. Their use is barbarous, because they produce increased suffering without any corresponding advantage to those using them.
The enemy could not resort to our method to protect their men, because we had an inexhaustible supply of ammunition to draw upon and used it freely. Splinters from the timber would have made havoc among the men behind.
There were no mortars with the besiegers, except what the navy had in front of the city; but wooden ones were made by taking logs of the toughest wood that could be found, boring them out for six or twelve pound sh.e.l.ls and binding them with strong iron bands. These answered as cochorns, and sh.e.l.ls were successfully thrown from them into the trenches of the enemy.
The labor of building the batteries and intrenching was largely done by the pioneers, a.s.sisted by negroes who came within our lines and who were paid for their work; but details from the troops had often to be made.
The work was pushed forward as rapidly as possible, and when an advanced position was secured and covered from the fire of the enemy the batteries were advanced. By the 30th of June there were two hundred and twenty guns in position, mostly light field-pieces, besides a battery of heavy guns belonging to, manned and commanded by the navy. We were now as strong for defence against the garrison of Vicksburg as they were against us; but I knew that Johnston was in our rear, and was receiving constant reinforcements from the east. He had at this time a larger force than I had had at any time prior to the battle of Champion"s Hill.
As soon as the news of the arrival of the Union army behind Vicksburg reached the North, floods of visitors began to pour in. Some came to gratify curiosity; some to see sons or brothers who had pa.s.sed through the terrible ordeal; members of the Christian and Sanitary a.s.sociations came to minister to the wants of the sick and the wounded. Often those coming to see a son or brother would bring a dozen or two of poultry.
They did not know how little the gift would be appreciated. Many of the soldiers had lived so much on chickens, ducks and turkeys without bread during the march, that the sight of poultry, if they could get bacon, almost took away their appet.i.te. But the intention was good.
Among the earliest arrivals was the Governor of Illinois, with most of the State officers. I naturally wanted to show them what there was of most interest. In Sherman"s front the ground was the most broken and most wooded, and more was to be seen without exposure. I therefore took them to Sherman"s headquarters and presented them. Before starting out to look at the lines--possibly while Sherman"s horse was being saddled --there were many questions asked about the late campaign, about which the North had been so imperfectly informed. There was a little knot around Sherman and another around me, and I heard Sherman repeating, in the most animated manner, what he had said to me when we first looked down from Walnut Hills upon the land below on the 18th of May, adding: "Grant is ent.i.tled to every bit of the credit for the campaign; I opposed it. I wrote him a letter about it." But for this speech it is not likely that Sherman"s opposition would have ever been heard of. His untiring energy and great efficiency during the campaign ent.i.tle him to a full share of all the credit due for its success. He could not have done more if the plan had been his own. (*13)
On the 26th of May I sent Blair"s division up the Yazoo to drive out a force of the enemy supposed to be between the Big Black and the Yazoo.
The country was rich and full of supplies of both food and forage.
Blair was instructed to take all of it. The cattle were to be driven in for the use of our army, and the food and forage to be consumed by our troops or destroyed by fire; all bridges were to be destroyed, and the roads rendered as nearly impa.s.sable as possible. Blair went forty-five miles and was gone almost a week. His work was effectually done. I requested Porter at this time to send the marine brigade, a floating nondescript force which had been a.s.signed to his command and which proved very useful, up to Haines" Bluff to hold it until reinforcements could be sent.
On the 26th I also received a letter from Banks, asking me to reinforce him with ten thousand men at Port Hudson. Of course I could not comply with his request, nor did I think he needed them. He was in no danger of an attack by the garrison in his front, and there was no army organizing in his rear to raise the siege.
On the 3d of June a brigade from Hurlbut"s command arrived, General Kimball commanding. It was sent to Mechanicsburg, some miles north-east of Haines" Bluff and about midway between the Big Black and the Yazoo.
A brigade of Blair"s division and twelve hundred cavalry had already, on Blair"s return from the Yazoo, been sent to the same place with instructions to watch the crossings of the Big Black River, to destroy the roads in his (Blair"s) front, and to gather or destroy all supplies.
On the 7th of June our little force of colored and white troops across the Mississippi, at Milliken"s Bend, were attacked by about 3,000 men from Richard Taylor"s trans-Mississippi command. With the aid of the gunboats they were speedily repelled. I sent Mower"s brigade over with instructions to drive the enemy beyond the Tensas Bayou; and we had no further trouble in that quarter during the siege. This was the first important engagement of the war in which colored troops were under fire.
These men were very raw, having all been enlisted since the beginning of the siege, but they behaved well.
On the 8th of June a full division arrived from Hurlbut"s command, under General Sooy Smith. It was sent immediately to Haines" Bluff, and General C. C. Washburn was a.s.signed to the general command at that point.
On the 11th a strong division arrived from the Department of the Missouri under General Herron, which was placed on our left. This cut off the last possible chance of communication between Pemberton and Johnston, as it enabled Lauman to close up on McClernand"s left while Herron intrenched from Lauman to the water"s edge. At this point the water recedes a few hundred yards from the high land. Through this opening no doubt the Confederate commanders had been able to get messengers under cover of night.
On the 14th General Parke arrived with two divisions of Burnside"s corps, and was immediately dispatched to Haines" Bluff. These latter troops--Herron"s and Parke"s--were the reinforcements already spoken of sent by Halleck in antic.i.p.ation of their being needed. They arrived none too soon.
I now had about seventy-one thousand men. More than half were disposed across the peninsula, between the Yazoo at Haines" Bluff and the Big Black, with the division of Osterhaus watching the crossings of the latter river farther south and west from the crossing of the Jackson road to Baldwin"s ferry and below.
There were eight roads leading into Vicksburg, along which and their immediate sides, our work was specially pushed and batteries advanced; but no commanding point within range of the enemy was neglected.
On the 17th I received a letter from General Sherman and one on the 18th from General McPherson, saying that their respective commands had complained to them of a fulsome, congratulatory order published by General McClernand to the 13th corps, which did great injustice to the other troops engaged in the campaign. This order had been sent North and published, and now papers containing it had reached our camps. The order had not been heard of by me, and certainly not by troops outside of McClernand"s command until brought in this way. I at once wrote to McClernand, directing him to send me a copy of this order. He did so, and I at once relieved him from the command of the 13th army corps and ordered him back to Springfield, Illinois. The publication of his order in the press was in violation of War Department orders and also of mine.
CHAPTER x.x.xVIII.
JOHNSTON"S MOVEMENTS--FORTIFICATIONS AT HAINES" BLUFF--EXPLOSION OF THE MINE--EXPLOSION OF THE SECOND MINE--PREPARING FOR THE a.s.sAULT--THE FLAG OF TRUCE--MEETING WITH PEMBERTON--NEGOTIATIONS FOR SURRENDER--ACCEPTING THE TERMS--SURRENDER OF VICKSBURG.
On the 22d of June positive information was received that Johnston had crossed the Big Black River for the purpose of attacking our rear, to raise the siege and release Pemberton. The correspondence between Johnston and Pemberton shows that all expectation of holding Vicksburg had by this time pa.s.sed from Johnston"s mind. I immediately ordered Sherman to the command of all the forces from Haines" Bluff to the Big Black River. This amounted now to quite half the troops about Vicksburg.
Besides these, Herron and A. J. Smith"s divisions were ordered to hold themselves in readiness to reinforce Sherman. Haines" Bluff had been strongly fortified on the land side, and on all commanding points from there to the Big Black at the railroad crossing batteries had been constructed. The work of connecting by rifle-pits where this was not already done, was an easy task for the troops that were to defend them.
We were now looking west, besieging Pemberton, while we were also looking east to defend ourselves against an expected siege by Johnston.
But as against the garrison of Vicksburg we were as substantially protected as they were against us. Where we were looking east and north we were strongly fortified, and on the defensive. Johnston evidently took in the situation and wisely, I think, abstained from making an a.s.sault on us because it would simply have inflicted loss on both sides without accomplishing any result. We were strong enough to have taken the offensive against him; but I did not feel disposed to take any risk of losing our hold upon Pemberton"s army, while I would have rejoiced at the opportunity of defending ourselves against an attack by Johnston.
From the 23d of May the work of fortifying and pushing forward our position nearer to the enemy had been steadily progressing. At three points on the Jackson road, in front of Leggett"s brigade, a sap was run up to the enemy"s parapet, and by the 25th of June we had it undermined and the mine charged. The enemy had countermined, but did not succeed in reaching our mine. At this particular point the hill on which the rebel work stands rises abruptly. Our sap ran close up to the outside of the enemy"s parapet. In fact this parapet was also our protection. The soldiers of the two sides occasionally conversed pleasantly across this barrier; sometimes they exchanged the hard bread of the Union soldiers for the tobacco of the Confederates; at other times the enemy threw over hand-grenades, and often our men, catching them in their hands, returned them.
Our mine had been started some distance back down the hill; consequently when it had extended as far as the parapet it was many feet below it.
This caused the failure of the enemy in his search to find and destroy it. On the 25th of June at three o"clock, all being ready, the mine was exploded. A heavy artillery fire all along the line had been ordered to open with the explosion. The effect was to blow the top of the hill off and make a crater where it stood. The breach was not sufficient to enable us to pa.s.s a column of attack through. In fact, the enemy having failed to reach our mine had thrown up a line farther back, where most of the men guarding that point were placed. There were a few men, however, left at the advance line, and others working in the countermine, which was still being pushed to find ours. All that were there were thrown into the air, some of them coming down on our side, still alive. I remember one colored man, who had been under ground at work when the explosion took place, who was thrown to our side. He was not much hurt, but terribly frightened. Some one asked him how high he had gone up. "Dun no, ma.s.sa, but t"ink "bout t"ree mile," was his reply. General Logan commanded at this point and took this colored man to his quarters, where he did service to the end of the siege.
As soon as the explosion took place the crater was seized by two regiments of our troops who were near by, under cover, where they had been placed for the express purpose. The enemy made a desperate effort to expel them, but failed, and soon retired behind the new line. From here, however, they threw hand-grenades, which did some execution. The compliment was returned by our men, but not with so much effect. The enemy could lay their grenades on the parapet, which alone divided the contestants, and roll them down upon us; while from our side they had to be thrown over the parapet, which was at considerable elevation. During the night we made efforts to secure our position in the crater against the missiles of the enemy, so as to run trenches along the outer base of their parapet, right and left; but the enemy continued throwing their grenades, and brought boxes of field ammunition (sh.e.l.ls), the fuses of which they would light with portfires, and throw them by hand into our ranks. We found it impossible to continue this work. Another mine was consequently started which was exploded on the 1st of July, destroying an entire rebel redan, killing and wounding a considerable number of its occupants and leaving an immense chasm where it stood. No attempt to charge was made this time, the experience of the 25th admonishing us.
Our loss in the first affair was about thirty killed and wounded. The enemy must have lost more in the two explosions than we did in the first. We lost none in the second.
From this time forward the work of mining and pushing our position nearer to the enemy was prosecuted with vigor, and I determined to explode no more mines until we were ready to explode a number at different points and a.s.sault immediately after. We were up now at three different points, one in front of each corps, to where only the parapet of the enemy divided us.
At this time an intercepted dispatch from Johnston to Pemberton informed me that Johnston intended to make a determined attack upon us in order to relieve the garrison at Vicksburg. I knew the garrison would make no formidable effort to relieve itself. The picket lines were so close to each other--where there was s.p.a.ce enough between the lines to post pickets--that the men could converse. On the 21st of June I was informed, through this means, that Pemberton was preparing to escape, by crossing to the Louisiana side under cover of night; that he had employed workmen in making boats for that purpose; that the men had been canva.s.sed to ascertain if they would make an a.s.sault on the "Yankees" to cut their way out; that they had refused, and almost mutinied, because their commander would not surrender and relieve their sufferings, and had only been pacified by the a.s.surance that boats enough would be finished in a week to carry them all over. The rebel pickets also said that houses in the city had been pulled down to get material to build these boats with. Afterwards this story was verified: on entering the city we found a large number of very rudely constructed boats.
All necessary steps were at once taken to render such an attempt abortive. Our pickets were doubled; Admiral Porter was notified, so that the river might be more closely watched; material was collected on the west bank of the river to be set on fire and light up the river if the attempt was made; and batteries were established along the levee crossing the peninsula on the Louisiana side. Had the attempt been made the garrison of Vicksburg would have been drowned, or made prisoners on the Louisiana side. General Richard Taylor was expected on the west bank to co-operate in this movement, I believe, but he did not come, nor could he have done so with a force sufficient to be of service. The Mississippi was now in our possession from its source to its mouth, except in the immediate front of Vicksburg and of Port Hudson. We had nearly exhausted the country, along a line drawn from Lake Providence to opposite Bruinsburg. The roads west were not of a character to draw supplies over for any considerable force.
By the 1st of July our approaches had reached the enemy"s ditch at a number of places. At ten points we could move under cover to within from five to one hundred yards of the enemy. Orders were given to make all preparations for a.s.sault on the 6th of July. The debouches were ordered widened to afford easy egress, while the approaches were also to be widened to admit the troops to pa.s.s through four abreast. Plank, and bags filled with cotton packed in tightly, were ordered prepared, to enable the troops to cross the ditches.
On the night of the 1st of July Johnston was between Brownsville and the Big Black, and wrote Pemberton from there that about the 7th of the month an attempt would be made to create a diversion to enable him to cut his way out. Pemberton was a prisoner before this message reached him.
On July 1st Pemberton, seeing no hope of outside relief, addressed the following letter to each of his four division commanders:
"Unless the siege of Vicksburg is raised, or supplies are thrown in, it will become necessary very shortly to evacuate the place. I see no prospect of the former, and there are many great, if not insuperable obstacles in the way of the latter. You are, therefore, requested to inform me with as little delay as possible, as to the condition of your troops and their ability to make the marches and undergo the fatigues necessary to accomplish a successful evacuation."
Two of his generals suggested surrender, and the other two practically did the same. They expressed the opinion that an attempt to evacuate would fail. Pemberton had previously got a message to Johnston suggesting that he should try to negotiate with me for a release of the garrison with their arms. Johnston replied that it would be a confession of weakness for him to do so; but he authorized Pemberton to use his name in making such an arrangement.
On the 3d about ten o"clock A.M. white flags appeared on a portion of the rebel works. Hostilities along that part of the line ceased at once. Soon two persons were seen coming towards our lines bearing a white flag. They proved to be General Bowen, a division commander, and Colonel Montgomery, aide-de-camp to Pemberton, bearing the following letter to me:
"I have the honor to propose an armistice for--hours, with the view to arranging terms for the capitulation of Vicksburg. To this end, if agreeable to you, I will appoint three commissioners, to meet a like number to be named by yourself at such place and hour to-day as you may find convenient. I make this proposition to save the further effusion of blood, which must otherwise be shed to a frightful extent, feeling myself fully able to maintain my position for a yet indefinite period.
This communication will be handed you under a flag of truce, by Major-General John S. Bowen."
It was a glorious sight to officers and soldiers on the line where these white flags were visible, and the news soon spread to all parts of the command. The troops felt that their long and weary marches, hard fighting, ceaseless watching by night and day, in a hot climate, exposure to all sorts of weather, to diseases and, worst of all, to the gibes of many Northern papers that came to them saying all their suffering was in vain, that Vicksburg would never be taken, were at last at an end and the Union sure to be saved.
Bowen was received by General A. J. Smith, and asked to see me. I had been a neighbor of Bowen"s in Missouri, and knew him well and favorably before the war; but his request was refused. He then suggested that I should meet Pemberton. To this I sent a verbal message saying that, if Pemberton desired it, I would meet him in front of McPherson"s corps at three o"clock that afternoon. I also sent the following written reply to Pemberton"s letter:
"Your note of this date is just received, proposing an armistice for several hours, for the purpose of arranging terms of capitulation through commissioners, to be appointed, etc. The useless effusion of blood you propose stopping by this course can be ended at any time you may choose, by the unconditional surrender of the city and garrison.
Men who have shown so much endurance and courage as those now in Vicksburg, will always challenge the respect of an adversary, and I can a.s.sure you will be treated with all the respect due to prisoners of war.
I do not favor the proposition of appointing commissioners to arrange the terms of capitulation, because I have no terms other than those indicated above."
