WASHINGTON, July 23. — The War Department is pushing the organization of colored troops vigorously. The successes of our forces in the West has given a fresh impetus to enlistments among the blacks. By autumn, it is estimated, 100,000 negroes will be in arms in the Valley of the Mississippi.
Intelligence has been received by Commissioner Dale of the safe removal of the Sioux and Winnebago Indians from Minnesota in pursuance of the act of Congress. They are now located on the Missouri river, a few miles above Fort Randall. All the goods of the Winnebagoes had arrived. The agent had a stockade agency. Everything was working well. No further difficulty is apprehended.
The recent expedition of Admiral Lee up James river was not intended to attack Fort Darling or any other place. It was simply a reconnoissance, the object of which being attained, Admiral Lee returned with his gunboats.
WASHINGTON, July 23. — The relative situation of the armies in Virginia to-day, is nearly understood here. It is apparent that Gen. Meade has the rebel army of Lee completely entrapped. He is evidently massing his forces to break his way through to Richmond, but will probably find it more difficult an undertaking than the affair at Gettysburg.
After all the delay there is now not much prospect of Lee being able to get his army back to Richmond, or even as far as the upper end of the Shenandoah Valley.
WASHINGTON, July 23. — Gen. Hooker has gone West. A rumor on the street says he is to relieve the present commander of the Department of Missouri, but thus far this is merely conjecture.
