Washington, D.C., June 18, 1862.
Yours of to-day making it probable that Jackson has been re-enforced by about 10,000 from Richmond is corroborated by a dispatch from General King at Fredericksburg, saying a Frenchman just arrived from Richmond by way of Gordonsville met 10,000 to 15,000 passing through the latter place to join Jackson.
If this is true it is as good as a re-enforcement to you of an equal force. I could better dispose of things if I could know about what day you can attack Richmond, and would be glad to be informed, if you think you can inform me with safety.
