O.R.-- SERIES I--VOLUME XVI/1 [S# 22] SEPTEMBER 18, 1862.--Affair at Glasgow, Ky. Report of Col. Lewis Zahm, Third Ohio Cavalry, commanding Second Cavalry Brigade. HEADQUARTERS SECOND CAVALRY BRIGADE, Glasgow, September 18, 1862--4 p.m. COLONEL: I have the honor to report my arrival here between 1 and 2 o'clock this p.m. I took about 200 prisoners, sick and well; have the well ones in my column, nearly 100. Took some 10 or 12 officers; had them paroled. Captured 5 wagons loaded with flour; a number of arms, &c. I learn from citizens, especially the editor here, that six divisions of the rebel army have passed northward to Green River and, as they suppose, to Louisville. The divisions are as follows: Generals Withers', Cheatham's, Hardee's, Buckner's, Anderson's, and Brown's, altogether estimated at 45,000 men, with about eighty pieces light artillery, mostly 10 and 12 pounders. General Bragg left here on Tuesday morning. They expect Breckinridge in to-morrow with a division numbering about 6,000. I sent out detachments on the pikes leading to Cumberland and Tompkinsville and other points. They returned without having made any discoveries. It is rumored that General Price is at Hopkinsville with his forces. I am getting my column in motion for Prewitt's Knob. I am, very respectfully, your obedient servant, LEWIS ZAHM, Second Cavalry Brigade. Col. J. B. FRY. I also captured a mail, which I send with this.
