Ennis Cross-Roads toward Sisters Ferry. My scout, writing at 2p. in., could not determine which way they would march, as wagons were going iu both directions. A considerable force moved up toward Roberts- yule, but it was only a reconnaissance. Scouts sent to vicinity of Gilli- sonville and Coosawhatchie report no force at the latter place except Fosters, numbering 3,000 to 4,000, principally negro troops; reports a small infantry camp near Grahamville; very little cavalry or signs of cavalry seen, though it was said a brigade of cavalry had gone out the Black Swamp road. The troops at Ennis Cross- L~oads had a star on their hats, which is the emblem of the Twentieth Corps. They had a wagon train with them. Respectfully, general, your obedient servant, J. WHEELER, Major- General. Maj. Gen. L. McLAwS, Commanding, fc. LAWTONVILLE, S. C., January 29, 1865. DEAR GENERAL: I write to inform you as well as possible of the situation of things in our immediate front. General Sherman no doubt first intended moving upon Branchville, but on reaching Poco- taligo I presume the high stage of water in the Combahee may have deterred him. He certainly is now moving either for Augusta or for some point on the railroad between Augusta and Bran chville; or he may yet turn and cross the Combahee above the railroad bridge and march direct upon Branchville. My best information is that the Fif- teenth, Seventeenth, and part of the Twentieth Corps are upon this side of the river, and that the Fourteenth is on the Georgia side. General Hill, in taking command of the District of Georgia, has relieved me of the charge of that portion of my command which is in Georgia, so that I can turn my attention more particularly to my troops in my immediate vicinity. The advance of the enemy on this side of the river is at Robertsville, and on the Georgia side at Sisters Ferry. I have had a pretty good line of works thrown up at the Lower Three Runs, but you know that my force cannot hold the enemy in check long when their force is so overwhelming. I see General Hill has issued some orders which I fear will frighten the good people of Augusta very much. The twenty days of picket duty I have had has been devoted to drill and discipline and study of tactics, which has improved my command very much. The stories which I have been surprised to find circulated, to the effect that my command lacked dis- cipline, were most false. It is the best disciplined cavalry in the Con- federacy, and I can prove by the best citizens of Beaufort District that they have never known soldiers to treat people or property so well. Although I have tried to do so, I have not been able to find a citizen who had even to complain that a single rail had been burned. With highest respect, your obedient servant and friend, J. WHEELER. General BRAXTON BRAGG, lid qrs. Armies of the Coifederate States. JANUARY 30. P. S...Prisoners belonging to the Twentieth Army Corps, captured near Robertsville, state that the talk in camp is they are going to Augusta, and that they will move early to-morrow morning. They also state that their command was delayed to-day cutting out the blockades and to get up their forces, so as to ascertain what is in their immediate front.
