CULPEPPER, VA., Feb. 64.HERE I am pretty well down toward the extreme front. Three or four days ago General S., who is now in chief command, (I believe Meade is absent, sick,) moved a strong force southward from camp as if intending business. They went to the Rapidan; there has since been some manuvring and a little fighting, but nothing of consequence. The telegraphic accounts given Monday morning last, make entirely too much of it, I should say. What General S. intended we here know not, but we trust in that competent commander. We were somewhat excited, (but not so very much either,) on Sunday, during the day and night, as orders were sent out to pack up and harness, and be ready to evacuate, to fall back towards Washington. But I was very sleepy and went to bed. Some tremendous shouts arousing me during the night, I went forth and found it was from the men above mentiond, who were returning. I talkd with some of the men; as usual I found them full of gayety, endurance, and many fine little outshows, the signs of the most excellent good manliness of the world. It was a curious sight to see those shadowy columns moving through the night. I stood unobservd in the darkness and watchd them long. The mud was very deep. The men had their usual burdens, overcoats. knapsacks, guns and blankets. Along and along they filed by me, with often a laugh, a song, a cheerful word, but never once a murmur. It may have been odd, but I never before so realized the majesty and reality of the American people en masse. It fell upon me like a great awe. The strong ranks moved neither fast nor slow. They had marchd seven or eight miles already through the slipping unctuous mud. The brave First corps stopt here. The equally brave Third corps moved on to Brandy station. The famous Brooklyn 14th are here, guarding the town. You see their red legs actively moving everywhere. Then they have a theatre of their own here. They give musical performances, nearly everything done capitally. Of course the audience is a jam. It is a good sport to attend one of these entertainments of the 14th. I like to look around the soldiers, and the general collection in front of the curtain, more than the scene on the stage.
