MCCLELLAN'S HEADQUARTERS,

October 5, 1862-11 a. m.

I received a report last night that the railroad bridge across the Little Cacapon, near Cumberland, was destroyed by 1,500 of Stuart's cavalry on the night previous, and that the same party had capture a company of the Fifty-fourth Pennsylvania Volunteers. Colonel McReynolds, with two regiments of our cavalry, was there, or in the immediate vicinity, as also General Kelley, for the express purpose of preventing such raids. I ordered Colonel Averell last night to proceed rapidly from Williamsport, with four regiments of cavalry and a horse battery, to that section, and to use his utmost endeavors to chastise Stuart's party. He will act vigorously, and I confidently anticipate some good, results.

GEO. B. McCLELLAN,
