Huntsville, Sunday, May 1. On guard as supernumerary, and instead of attending Sabbath school at 9 A. M. as I would wish, I underwent the ceremony of brigade guard mounting, inspection of arms, drums and fifes, etc. for nearly an hour. A very beautiful day. Two brigades of Dodge’s command came in this afternoon, one from Athens, the other from Pulaski. They go to join in the forward movement. Gen. John A. Logan left to-day with staff and escort for the front, a gay and dashing cavalcade. May the rebels tremble when they hear his approach.
