Telegram To General I. Mcdowell.
Washington, May 28, 1862.

GENERAL McDOWELL, Manassas Junction:

General McClellan at 6.30 P.M. yesterday telegraphed that Fitz-John Porter's division had fought and driven 13,000 of the enemy, under General Branch, from Hanover Court-House, and was driving them from a stand they had made on the railroad at the time the messenger left. Two hours later he telegraphed that Stoneman had captured an engine and six cars on the Virginia Central, which he at once sent to communicate with Porter. Nothing further from McClellan.

If Porter effects a lodgment on both railroads near Hanover Court-House, consider whether your forces in front of Fredericksburg should not push through and join him.

A. LINCOLN.
