From Gen. Floyd's command.
Lynchburg, Nov. 28.
--The Republican will publish to-morrow a letter from a prominent officer in General Floyd's command, dated at Camp Mercer, November 25th, which gives a detailed account of movements since leaving Cotton Hill.
A number of skirmishes have occurred, some of which were general in character; but in none of them did our forces sustain but slight loss, while the enemy suffered greatly.
We lost only a few tents in our retreat.
The command expect to go into winter quarters at Peterstown, in Monroe county.
The roads are almost impassable; and it is thought that neither the Yankees nor ourselves can accomplish anything until next spring.
