From Northern Virginia.
The battle reported at Catlett's Station on Wednesday turns out to have been a cavalry skirmish, in which we took some prisoners.
There was some hard fighting late Wednesday evening at Bristow Station. We were driving the enemy back when the skirmishers fell upon McIntosh's Artillery, supported by Cook's brigade.
Gen. Cook was wounded early in the action. His brigade was thrown into confusion, during which the enemy succeeded in taking five pieces of artillery.
Reinforcements coming up, we were pursuing the enemy at last advices towards Dumfries.
Our loss is about five hundred killed and wounded. Gens. Posey and Kirkland were wounded — the former badly in the thigh.
About fifteen hundred prisoners have been gathered during the day.
Heavy firing was heard Thursday in direction of Manassas. Many rumors are afloat, but nothing reliable has yet been received.

The battle at Bristow Station, reported yesterday, was an engagement between parts of the two armies. It is reported that but for some deserters going over to the enemy and giving information on the day our forces commenced moving, we should have achieved a much more substantial success.
