A force of about two thousand, cavalry passed through Grand Junction north last Friday, and fell on a detachment of the Bolivar army at Middleburg, the result of which is doubtless reported to you.

As soon as I heard of the movement, I dispatched a force to the southeast by way of diversion, and am satisfied that the enemy's infantry and artillery fell back in consequence behind the Tallahatchie.

The weather is very hot, country very dry, and dust as bad as possible.

I hold my two divisions ready, with their original complement of transportation, for field service.

Of course all things most now depend on events in front of Washington and in Kentucky.
