July 31 1863. With Vicksburg fallen, I am forced to return the Ninth Army Corps to the Department of the Ohio. I issued the following special order,
SPECIAL ORDERS, HDQRS. DEPARTMENT OF THE TENNESSEE Number 207. Vicksburg, MISS., July 31, 1863.
VI. The NINTH Army Corps, Major General J. G. Parke commanding, will return to the Department of the Ohio as rapidly as transportation can be provided. On arriving at Cairo, General Parke will telegraph to the General-in-Chief of the army and to Major-General Burnside for further instructions.
The provost-marshal-general of this army will send north all prisoners of war not authorized to be paroled, in charge of the NINTH Army Corps. They will be left at Indianapolis, or such other point as the General-in-Chief may direct.
In returning the NINTH Army Corps to its former command, it is with pleasure that the general commanding acknowledges its valuable services in the campaign just closed. Arriving at Vicksburg opportunely, taking position to hold at bay Johnston’s army, then, threatening the forces investing the city, it was ready and eager to assume the aggressive at any moment. After the fall of Vicksburg, it formed a part of the army which drove Johnston from his position near the Big Black River into his intrenchments at Jackson, and, after a siege of eight days, compelled him to-fly in disorder from the Mississippi Valley. The endurance, valor, and general good conduct of the NINTH Corps are admired by all, and its valuable co-operation in achieving the final triumph of the campaign is gratefully acknowledged by the Army of the Tennessee.
Major-General Parke will cause the different regiments and batteries of his command to inscribe upon their banners and guidons “Vicksburg” and “Jackson. ”
By order of Major General U. S. Grant:
