After the war, Ulysses S. Grant reflected on the immediate consequences of the fall of Vicksburg. One of the more surprising consequences for readers of history who are used reading about the Confederate army capturing and using Union weapons was the way Grant's army re-equipped itself with the Enfield rifles captured from Pemberton's men. From Grant's memoirs.
The first dispatch I received from the government after the fall of
Vicksburg was in these words:
"I fear your paroling the prisoners at Vicksburg, without actual delivery to a proper agent as required by the seventh article of the cartel, may be construed into an absolute release, and that the men will immediately be placed in the ranks of the enemy. Such has been the case elsewhere. If these prisoners have not been allowed to depart, you will detain them until further orders."Halleck did not know that they had already been delivered into the hands of Major Watts, Confederate commissioner for the exchange of prisoners.
At Vicksburg 31,600 prisoners were surrendered, together with 172 cannon about 60,000 muskets and a large amount of ammunition. The small-arms of the enemy were far superior to the bulk of ours. Up to this time our troops at the West had been limited to the old United States flint-lock muskets changed into percussion, or the Belgian musket imported early in the war—almost as dangerous to the person firing it as to the one aimed at—and a few new and improved arms. These were of many different calibers, a fact that caused much trouble in distributing ammunition during an engagement. The enemy had generally new arms which had run the blockade and were of uniform caliber. After the surrender I authorized all colonels whose regiments were armed with inferior muskets, to place them in the stack of captured arms and replace them with the latter. A large number of arms turned in to the Ordnance Department as captured, were thus arms that had really been used by the Union army in the capture of Vicksburg.
In this narrative I have not made the mention I should like of officers, dead and alive, whose services entitle them to special mention. Neither have I made that mention of the navy which its services deserve. Suffice it to say, the close of the siege of Vicksburg found us with an army unsurpassed, in proportion to its numbers, taken as a whole of officers and men. A military education was acquired which no other school could have given. Men who thought a company was quite enough for them to command properly at the beginning, would have made good regimental or brigade commanders; most of the brigade commanders were equal to the command of a division, and one, Ransom, would have been equal to the command of a corps at least. Logan and Crocker ended the campaign fitted to command independent armies.
General F. P. Blair joined me at Milliken's Bend a full-fledged general, without having served in a lower grade. He commanded a division in the campaign. I had known Blair in Missouri, where I had voted against him in 1858 when he ran for Congress. I knew him as a frank, positive and generous man, true to his friends even to a fault, but always a leader. I dreaded his coming; I knew from experience that it was more difficult to command two generals desiring to be leaders than it was to command one army officered intelligently and with subordination. It affords me the greatest pleasure to record now my agreeable disappointment in respect to his character. There was no man braver than he, nor was there any who obeyed all orders of his superior in rank with more unquestioning alacrity. He was one man as a soldier, another as a politician.
The navy under Porter was all it could be, during the entire campaign. Without its assistance the campaign could not have been successfully made with twice the number of men engaged. It could not have been made at all, in the way it was, with any number of men without such assistance. The most perfect harmony reigned between the two arms of the service. There never was a request made, that I am aware of, either of the flag-officer or any of his subordinates, that was not promptly complied with.
The campaign of Vicksburg was suggested and developed by circumstances. The elections of 1862 had gone against the prosecution of the war. Voluntary enlistments had nearly ceased and the draft had been resorted to; this was resisted, and a defeat or backward movement would have made its execution impossible. A forward movement to a decisive victory was necessary. Accordingly I resolved to get below Vicksburg, unite with Banks against Port Hudson, make New Orleans a base and, with that base and Grand Gulf as a starting point, move our combined forces against Vicksburg. Upon reaching Grand Gulf, after running its batteries and fighting a battle, I received a letter from Banks informing me that he could not be at Port Hudson under ten days, and then with only fifteen thousand men. The time was worth more than the reinforcements; I therefore determined to push into the interior of the enemy's country.
With a large river behind us, held above and below by the enemy, rapid movements were essential to success. Jackson was captured the day after a new commander had arrived, and only a few days before large reinforcements were expected. A rapid movement west was made; the garrison of Vicksburg was met in two engagements and badly defeated, and driven back into its stronghold and there successfully besieged. It looks now as though Providence had directed the course of the campaign while the Army of the Tennessee executed the decree.
Upon the surrender of the garrison of Vicksburg there were three things that required immediate attention. The first was to send a force to drive the enemy from our rear, and out of the State. The second was to send reinforcements to Banks near Port Hudson, if necessary, to complete the triumph of opening the Mississippi from its source to its mouth to the free navigation of vessels bearing the Stars and Stripes. The third was to inform the authorities at Washington and the North of the good news, to relieve their long suspense and strengthen their confidence in the ultimate success of the cause they had so much at heart.
Soon after negotiations were opened with General Pemberton for the surrender of the city, I notified Sherman, whose troops extended from Haines' Bluff on the left to the crossing of the Vicksburg and Jackson road over the Big Black on the right, and directed him to hold his command in readiness to advance and drive the enemy from the State as soon as Vicksburg surrendered. Steele and Ord were directed to be in readiness to join Sherman in his move against General Johnston, and Sherman was advised of this also. Sherman moved promptly, crossing the Big Black at three different points with as many columns, all concentrating at Bolton, twenty miles west of Jackson.
