Manassas, Va.
May 24, 1861
General Lee
   By all accounts, the enemy crossed the river last night in large force. They stopped the Leesburg train {on the Alexandria, Loudoun & Hampshire RR} six miles from Alexandria, a reliable man informs me, who saw them. They may be moving on Leesburg possibly on us. I have just heard from Hunton. He has taken necessary measures to prevent surprise by rail, but they will not move that way. *****
