and some time was vainly spent in skirmishing the mountain with my dismounted cavalry and Company E, Fifth Artillery. the localities of the pieces was even a secret not imparted to many of Mosby's men. By intimidation, however, when almost relinquishing the task, a driver of the artillery was forced to discover the trail of the pieces. By deploying skirmishers and moving up the precipitous side fa the mountain, covered with heavy undergrowth, for about a mile and a half, and following its summit for some distance, the three-inch ordnance gun, 12-pounder howitzer, and two small mountain howitzers, whit limber of caisson, sets of harness, and ammunition, were discovered in a dense thicket. These were drawn down the stony sides of the mountain to the command below, and thence to Piedmont, reaching camp at 6 a. m. to-day. I desire to mention Lieutenant Revell, Thirteenth New York Cavalry, and Captain anderson, Company E, Fifth Artillery, who rendered valuable assistance. As desired, I have dismounted the pieces with the exception of the small mountain howitzer, weighing only 250 pounds, which I have repaired, replenished whit ammunition, and would respectfully ask permission to retain whit my regiment till it returns to camp. I have it drawn by two horses, an manned by old artillerists. The other three pieces are sent by train as you directed. Prisoners, seven of whom I send, report that a force is expected here from the rebel column int he Valley.
I am, very respectfully, you obedient servant,
H. S. GANSEVOORT,
Colonel Thirteenth New York Cavalry.
