General Banks had a number of copies of this letter printed, or at least a synopsis of it, and very soon a copy fell into the hands of General Gardner, who was then in command of Port Hudson. Gardner at once sent a letter to the commander of the National forces saying that he had been informed of the surrender of Vicksburg and telling how the information reached him. He added that if this was true, it was useless for him to hold out longer. General Banks gave him assurances that Vicksburg had been surrendered, and General Gardner surrendered unconditionally on the 9th of July. Port Hudson with nearly 6,000 prisoners, 51 guns, 5,000 small-arms and other stores fell into the hands of the Union forces: from that day to the close of the rebellion the Mississippi River, from its source to its mouth, remained in the control of the National troops.
Pemberton and his army were kept in Vicksburg until the whole could be paroled. The paroles were in duplicate, by organization (one copy for each, Federals and Confederates), and signed by the commanding officers of the companies or regiments. Duplicates were also made for each soldier and signed by each individually, one to be retained by the soldier signing and one to be retained by us. Several hundred refused to sign their paroles, preferring to be sent to the North as prisoners to being sent back to fight again. Others again kept out of the way, hoping to escape either alternative.
Pemberton appealed to me in person to compel these men to sign their paroles, but I declined. It also leaked out that many of the men who had signed their paroles, intended to desert and go to their homes as soon as they got out of our lines. Pemberton hearing this, again appealed to me to assist him. He wanted arms for a battalion, to act as guards in keeping his men together while being marched to a camp of instruction, where he expected to keep them until exchanged. This request was also declined. It was precisely what I expected and hoped that they would do. I told him, however, that I would see that they marched beyond our lines in good order. By the eleventh, just one week after the surrender, the paroles were completed and the Confederate garrison marched out. Many deserted, and fewer of them were ever returned to the ranks to fight again than would have been the case had the surrender been unconditional and the prisoners sent to the James River to be paroled.
As soon as our troops took possession of the city guards were established along the whole line of parapet, from the river above to the river below. The prisoners were allowed to occupy their old camps behind the intrenchments. No restraint was put upon them, except by their own commanders. They were rationed about as our own men, and from our supplies. The men of the two armies fraternized as if they had been fighting for the same cause. When they passed out of the works they had so long and so gallantly defended, between lines of their late antagonists, not a cheer went up, not a remark was made that would give pain. Really, I believe there was a feeling of sadness just then in the breasts of most of the Union soldiers at seeing the dejection of their late antagonists.
The day before the departure the following order was issued:
"Paroled prisoners will be sent out of here to-morrow. They will be authorized to cross at the railroad bridge, and move from there to Edward's Ferry, (*14) and on by way of Raymond.
Instruct the commands to be orderly and quiet as these prisoners pass, to make no offensive remarks, and not to harbor any who fall out of ranks after they have passed."
