to-day, which will make the aggregate present for duty about 4,200. The infantry men detailed for duty in Captain Parsons' battery have been returned to their regiments and supplied with arms and ammunition. Captain Harris' battery is supplied with horses and ammunition and is in good condition for service.

The regiments are all supplied with ammunition, and every effort is being made to have the command in condition for active service whenever it may be called upon.

Very respectfully, your obedient servant,

A. McD. McCOOK,

Major-General.

The rain to-day has prevented our making the march intended. We will be at Perryville without fail to-morrow, I think.

LOUISVILLE, KY., October 10, 1862 - 2 p. m.

Major General H. W. HALLECK, General-in-Chief:

Men from Tennessee report Breckinridge moving northward. Some believe his purpose is to attack Nashville; others believe he is coming up to re-enforce Bragg. I have no doubt he is in Tennessee. Terrible battle yesterday near Perryville. Buell drove Bragg 8 miles, with great slaughter on both sides. Generals Jackson, Terrill, Lytle, and Webster killed. No further particulars. I have detained Governor Johnson's messenger until I hear from you.

J. T. BOYLE,

Brigadier-General.
