jH£ DOLLAR PER ANNUM INVARIABLY IN ADVANCE. TOWANDA : Thursday Morning, January 16,1862. Letter from Camp Pierpont CAMP PIKRPONT, Va., Dec. 21,1361. PSAR FBISSO :-Your vr, cloome letter wa. received niglit tefore last, aud I ' m P roVe th(f first opportunity of repljiw About 11 Sk of the night 1 recei.ed joor letter, we recti'ed orders to b- ready, with one da, sra St 0 march at 0 o'clock the next morn, The morning found your humble .errant and six other member, of our baud all ' who ere in marching order), prepared with a. hunk_of bread and a piece of beef, for a marcK We got under way at 7 o'clock, a ra.. and menced the march, the column consisting of tbe Third Brigade, I' RC , Gen. G KD 15001 mandin", together with part of a Regiment of Cavalry one battery of four guns and the Bucktaii Rifles. We inarched 12 miles to prainesville, and bad a sharp fight, as you probably have learned by the papers long be fore you will get this. One Regiment of our Brigade was superintending the loading of wagons with foruge, aud was not engaged in the %bt— so 'hat our force was less than three thousand men. The enemy knowing we were coming had chosen their ground and planted their battery. Our skiruiistiers were out and the first intimation given was just as we were i eoteriug Draiuesville, when one of them came running in, saying the enemy were coming up nas up that road. The Cavalry and Artil ,rr were in advance ; oar rear wholly unpro iccted, save by the 12ih Regiment Baud with cot arms or horns, (if we had had the latter te might possibly huve scared them back.) — The rebels did not advance upon our rear, but opened upon us with shell from their battery. Vou may believe there was lively work among oar troops A line of battle was immediately formed iu the road, by the iulautry, nearly in the position they occupied at the tin; • the alarm was giveu. The artillery wheeled to take positiou, supported by cavalry, and the ' Bucktaiis came back to our left aud uiade for the rehtls with their uuerring rifles. The ar tillery in getting position, turned one o. their heaviest guns clear over, it being on aside bill, ami with it the wheel horses clear on their backs This hindered some, hot they were soon all right, ai d opened on them with good effect. AH this was done iu less tune then 1 Lav. been writing H ; the rebels all the while si'iiiliinr their shell which were whizing about us but fortunately doing no damage. Our Quarter Master had his cap knocked off vvitli a piece of a shell as it burs' By 'his time the riflemen hud s;ot up in the field near enough to lie on their bellies and pick the re- Ms as they showed themselves in tTie edge of i lie wo tls The infantry, too, tiudiug the en- I my would not leave their cover ami advance '-pou '.liecn, made an advance, so that the en gagement was general. The battle raged about an hour aud a half, when there was a general route of the eneuoy. Blankets, overcoats, hav ersacks, Ac., being thrown iu piles by the road ir entire loss could not have been much less tl iu one hundred. I think there were but * ve of our men killed, and probably twenty rthrty wounded. It is astonishing (their u*iog advantage of position and waiting for oar men IO come on) how badly they were wVpped, aud if I had not seen it I could hard ly Mieve it. We did uot lose a man by their artillery.— T'H-T fired too high, while ours seat out a re jorter to see the effect of the shots ; he came in and said they were a little too high, the aim *as changed and men, horses, and trees were mowed down like grass One shot struck their magarne causing an explosion. Trees of pine , M large as mv body were cut dowu by the can ton halls A grf-at deal of credit is due the riflemen. Th-y are always found iu the thickest of the -•ght, and they make about every shot tell.— d a space uot more than two rods square I i4w I think, not less than twenty dead rebels -hot by the Bucktaiis while lying in front of ''hem in an open fi Id, while they (the Buck Ms) had only one man killed while in this po sitiou—this, too, with onr men io an opeu field Ml the rebels skulking behind trees The brilliant result of the battle is owing, I 'hick, principally to the accurate shots of our ®"n ami the miserable random firing of the
