It was not a council of war, but a mere consultation, resulting in orders from General Grant for us to make all possible preparations for a renewed assault on the 22d, simultaneously, at 10 a.m. I reconnoitred my front thoroughly in person, from right to left, and concluded to make my real attack at the right flank of the bastion, where the graveyard road entered the enemy's intrenchments, and at another point in the curtain about a hundred yards to its right (our left); also to make a strong demonstration by Steele's division, about a mile to our right, toward the river. All our field batteries were put in position, and were covered by good epaulements; the troops were brought forward, in easy support, concealed by the shape of the ground; and to the: minute, viz., 10 a.m. of May 22d, the troops sprang to the assault. A small party, that might be called a forlorn hope, provided with plank to cross the ditch, advanced at a run, up to the very ditch; the lines of infantry sprang from cover, and advanced rapidly in line of battle. I took a position within two hundred yards of the rebel parapet, on the off slope of a spur of ground, where by advancing two or three steps I could see every thing. The rebel line, concealed by the parapet, showed no sign of unusual activity, but as our troops came in fair view, the enemy rose behind their parapet and poured a furious fire upon our lines; and, for about two hours, we had a severe and bloody battle, but at every point we were repulsed. In the very midst of this, when shell and shot fell furious and fast, occurred that little episode which has been celebrated in song and story, of the boy Orion P. Howe, badly wounded, bearing me a message for cartridges, calibre 54, described in my letter to the Hon. E. M. Stanton, Secretary of War. This boy was afterward appointed a cadet to the United States Naval Academy, at Annapolis, but he could not graduate, and I do not now know what has become of him.

After our men had been fairly beaten back from off the parapet, and had got cover behind the spurs of ground close up to the rebel works, General Grant came to where I was, on foot, having left his horse some distance to the rear. I pointed out to him the rebel works, admitted that my assault had failed, and he said the result with McPherson and McClernand was about the same. While he was with me, an orderly or staff-officer came and handed him a piece of paper, which he read and handed to me. I think the writing was in pencil, on a loose piece of paper, and was in General McClernand's handwriting, to the effect that "his troops had captured the rebel parapet in his front," that, "the flag of the Union waved over the stronghold of Vicksburg," and asking him (General Grant) to give renewed orders to McPherson and Sherman to press their attacks on their respective fronts, lest the enemy should concentrate on him (McClernand). General Grant said, "I don't believe a word of it;" but I reasoned with him, that this note was official, and must be credited, and I offered to renew the assault at once with new troops. He said he would instantly ride down the line to McClernand's front, and if I did not receive orders to the contrary, by 3 o'clock p.m., I might try it again. Mower's fresh brigade was brought up under cover, and some changes were made in Giles Smith's brigade; and, punctually at 3 p.m., hearing heavy firing down along the line to my left, I ordered the second assault. It was a repetition of the first, equally unsuccessful and bloody. It also transpired that the same thing had occurred with General McPherson, who lost in this second assault some most valuable officers and men, without adequate result; and that General McClernand, instead of having taken any single point of the rebel main parapet, had only taken one or two small outlying lunettes open to the rear, where his men were at the mercy of the rebels behind their main parapet, and most of them were actually thus captured. This affair caused great feeling with us, and severe criticisms on General McClernand, which led finally to his removal from the command of the Thirteenth Corps, to which General Ord succeeded. The immediate cause, however, of General McClernand's removal was the publication of a sort of congratulatory order addressed to his troops, first published in St. Louis, in which he claimed that he had actually succeeded in making a lodgment in Vicksburg, but had lost it, owing to the fact that McPherson and Sherman did not fulfill their parts of the general plan of attack. This was simply untrue. The two several assaults made May 22d, on the lines of Vicksburg, had failed, by reason of the great strength of the position and the determined fighting of its garrison. I have since seen the position at Sevastopol, and without hesitation I declare that at Vicksburg to have been the more difficult of the two.

Thereafter our proceedings were all in the nature of a siege. General Grant drew more troops from Memphis, to prolong our general line to the left, so as completely to invest the place on its land-side, while the navy held the river both above and below. General Mower's brigade of Tuttle's division was also sent across the river to the peninsula, so that by May 31st Vicksburg was completely beleaguered. Good roads were constructed from our camps to the several landing-places on the Yazoo River, to which points our boats brought us ample supplies; so that we were in a splendid condition for a siege, while our enemy was shut up in a close fort, with a large civil population of men, women, and children to feed, in addition to his combatant force. If we could prevent sallies, or relief from the outside, the fate of the garrison of Vicksburg was merely a question of time.

I had my headquarters camp close up to the works, near the centre of my corps, and General Grant had his bivouac behind a ravine to my rear. We estimated Pemberton's whole force in Vicksburg at thirty thousand men, and it was well known that the rebel General Joseph E. Johnston was engaged in collecting another strong force near the Big Black, with the intention to attack our rear, and thus to afford Pemberton an opportunity to escape with his men. Even then the ability of General Johnston was recognized, and General Grant told me that he was about the only general on that side whom he feared. Each corps kept strong pickets well to the rear; but, as the rumors of Johnston's accumulating force reached us, General Grant concluded to take stronger measures. He had received from the North General J. G. Parker's corps (Ninth), which had been posted at Haines's Bluff; then, detailing one division from each of the three corps d'armee investing Vicksburg, he ordered me to go out, take a general command of all, and to counteract any movement on the part of General Johnston to relieve Vicksburg. I reconnoitred the whole country, from Haines's Bluff to the railroad bridge, and posted the troops thus:

Parke's two divisions from Haines's Bluff out to the Benton or ridge road; Tuttle's division, of my corps, joining on and extending to a plantation called Young's, overlooking Bear Creek valley, which empties into the Big Black above Messinger's Ferry; then McArthurs division, of McPherson's corps, took up the line, and reached to Osterhaus's division of McClernand's corps, which held a strong fortified position at the railroad-crossing of the Big Black River. I was of opinion that, if Johnston should cross the Big Black, he could by the favorable nature of the country be held in check till a concentration could be effected by us at the point threatened. From the best information we could gather, General Johnston had about thirty or forty thousand men. I took post near a plantation of one Trible, near Markham's, and frequently reconnoitred the whole line, and could see the enemy engaged in like manner, on the east aide of Big Black; but he never attempted actually to cross over, except with some cavalry, just above Bear Creek, which was easily driven back. I was there from June 20th to the 4th of July. In a small log-house near Markham's was the family of Mr. Klein, whose wife was the daughter of Mrs. Day, of New Orleans, who in turn was the sister of Judge T. W. Bartley, my brother-in-law. I used frequently to drop in and take a meal with them, and Mrs. Klein was generally known as the general's cousin, which doubtless saved her and her family from molestation, too common on the part of our men.

One day, as I was riding the line near a farm known as Parson Fog's, I heard that the family of a Mr. Wilkinson, of New Orleans, was "refugeeing" at a house near by. I rode up, inquired, and found two young girls of that name, who said they were the children of General Wilkinson, of Louisiana, and that their brother had been at the Military School at Alexandria. Inquiring for their mother, I was told she was spending the day at Parson Fox's. As this house was on my route, I rode there, went through a large gate into the yard, followed by my staff and escort, and found quite a number of ladies sitting on the porch. I rode up and inquired if that were Parson Fox's. The parson, a fine-looking, venerable old man, rose, and said that he was Parson Fox. I then inquired for Mrs. Wilkinson, when an elderly lady answered that she was the person. I asked her if she were from Plaquemine Parish, Louisiana, and she said she was. I then inquired if she had a son who had been a cadet at Alexandria when General Sherman was superintendent, and she answered yes. I then announced myself, inquired after the boy, and she said he was inside of Vicksburg, an artillery lieutenant. I then asked about her husband, whom I had known, when she burst into tears, and cried out in agony, "You killed him at Bull Run, where he was fighting for his country!" I disclaimed killing anybody at Bull Run; but all the women present (nearly a dozen) burst into loud lamentations, which made it most uncomfortable for me, and I rode away. On the 3d of July, as I sat at my bivouac by the road-side near Trible's, I saw a poor, miserable horse, carrying a lady, and led by a little negro boy, coming across a cotton-field toward me; as they approached I recognized poor Mrs. Wilkinson, and helped her to dismount. I inquired what had brought her to me in that style, and she answered that she knew Vicksburg, was going to surrender, and she wanted to go right away to see her boy. I had a telegraph-wire to General Grant's headquarters, and had heard that there were symptoms of surrender, but as yet nothing definite. I tried to console and dissuade her, but she was resolved, and I could not help giving her a letter to General Grant, explaining to him who she was, and asking him to give her the earliest opportunity to see her son. The distance was fully twenty miles, but off she started, and I afterward learned that my letter had enabled her to see her son, who had escaped unharmed. Later in the day I got by telegraph General Grant's notice of the negotiations for surrender; and, by his directions, gave general orders to my troops to be ready at a moment's notice to cross the Big Black, and go for Joe Johnston.

The next day (July 4, 1863) Vicksburg surrendered, and orders were given for at once attacking General Johnston. The Thirteenth Corps (General Ord) was ordered to march rapidly, and cross the Big Black at the railroad-bridge; the Fifteenth by Mesainger's, and the Ninth (General Parker) by Birdsong's Ferry-all to converge on Bolton. My corps crossed the Big Black during the 5th and 6th of July, and marched for Bolton, where we came in with General Ord's troops; but the Ninth Corps was delayed in crossing at Birdsong's. Johnston had received timely notice of Pemberton's surrender, and was in full retreat for Jackson. On the 8th all our troops reached the neighborhood of Clinton, the weather fearfully hot, and water scarce. Johnston had marched rapidly, and in retreating had caused cattle, hogs, and sheep, to be driven into the ponds of water, and there shot down; so that we had to haul their dead and stinking carcasses out to use the water. On the l0th of July we had driven the rebel army into Jackson, where it turned at bay behind the intrenchments, which had been enlarged and strengthened since our former visit in May. We closed our lines about Jackson; my corps (Fifteenth) held the centre, extending from the Clinton to the Raymond road; Ord's (Thirteenth) on the right, reaching Pearl River below the town; and Parker's (Ninth) the left, above the town.

On the 11th we pressed close in, and shelled the town from every direction. One of Ords brigades (Lauman's) got too close, and was very roughly handled and driven back in disorder. General Ord accused the commander (General Lauman) of having disregarded his orders, and attributed to him personally the disaster and heavy loss of men. He requested his relief, which I granted, and General Lauman went to the rear, and never regained his division. He died after the war, in Iowa, much respected, as before that time he had been universally esteemed a most gallant and excellent officer. The weather was fearfully hot, but we continued to press the siege day and night, using our artillery pretty freely; and on the morning of July 17th the place was found evacuated. General Steele's division was sent in pursuit as far as Brandon (fourteen miles), but General Johnston had carried his army safely off, and pursuit in that hot weather would have been fatal to my command.

Reporting the fact to General Grant, he ordered me to return, to send General Parkes's corps to Haines's Bluff, General Ord's back to Vicksburg, and he consented that I should encamp my whole corps near the Big Black, pretty much on the same ground we had occupied before the movement, and with the prospect of a period of rest for the remainder of the summer. We reached our camps on the 27th of July.

Meantime, a division of troops, commanded by Brigadier-General W. Sooy Smith, had been added to my corps. General Smith applied for and received a sick-leave on the 20th of July; Brigadier-General Hugh Ewing was assigned to its command; and from that time it constituted the Fourth Division of the Fifteenth Army Corps.
